Worried about passing autox tech inspection part 1

Worried about passing autox tech inspection
I just got my STi a little over a month ago, which now has 2500 miles. After a quick break-in period I went to the FCSCC auto-x beginners school and two FCSCC events after that. The car passed tech with no problems.

Two weekends ago I went to the season opener at Deven's. There the tech's found what felt like a bearing that was wearing out. With a ton of force pushing or pulling, depending on how the car is loaded, you could feel the wheel shift a tad. The tech inspector said that I couldn't compete in the next event unless I had it fixed.

I scheduled an appointment to have it fixed and tested the bearing myself 2 more times before I brought it in to make sure it wasn't something that didn't just disappear. Well the car is up on the rack right now and the mechanic tells me he can't find anything wrong with the bearing. I explained how I had tested it (pushing/pulling while on the ground) and that none of the other wheels exhibit the same behavior. He had it up on the rack, pushing and pulling and couldn't find anything wrong. He claims that perhaps I felt some slop in the tie rod, "Everything can't be tightened all the way down or parts will wear out too quickly."

When I was testing I had to put forth a lot of force to get the wheel to move a barely perceptible amount so I'm not at all worried about driving this on the street. My question is what do I have to do to pass tech for the next auto-x? The tech stated I had to have it fixed but the mechanic states there is no problem. The mechanic isn't stating that he won't replace it because it's not that bad, he's saying he won't replace it because nothing is wrong. It seems unreasonable to have to pay to replace what appears to be a functional bearing.

Any advice?

Thanks,
Mike

get it in writing from the mechanic
shouldn't be an issue

Is it the tech chief for your region that said this or just a volunteer?

I'd have the tech chief look at it and if he still doesn't like it tell him what the mechanic said.

It doesn't sound like you have any safety problems, and sometime the "techs" at autocrosses have no idea what they're talking about.

They were going to fail a brand new car! My car is two years old and they just look at it real quick and say Im good. The thing is new if the guy gives you beef next time tell him you took it in it's fine and to stop player hatting a guy in a new STI. If he still gives you bef have another guy tech it for you if you can.

To be honest, I have no idea. This was the first event I went to out there so I didn't know anyone. I am hoping that I can bring the printout of what was checked and I'll be fine.

Thanks for your quick replies guys!
614inda617 04-13-2004 03:36 PM

One thing I forgot to mention that struck me as odd; the tech said you can't really test wheel bearings on the ground. He claimed that the car has to be on a rack. I'm not sure whether to believe this or not. Of course when a bearing is really bad it's going to be obvious whether the car's on a rack or on the ground. I just find it hard to believe that you can't tell when the car is under load.
ANZAC_1915 04-13-2004 03:41 PM

It could be the ball joint in the control arm and the reverse is then potentially true, you'll get more play with it loaded than unloaded.

Exactly. If it's enough to be loose on the ground then there was something wrong with it. What I'm saying is... if there's play, there's something wrong. Did the mech at the dealership understand this? Did he have the wheel off when he was testing? Could it have been something as simple as loose lugnuts and the wheel itself moving? Can you repeat it now with the car on the ground after he looked at it?

Quite honestly, I'd be peeved at Subaru if there's slop in ANY driveline parts on an STi. There should be NO PLAY at ALL using the method above, especially on a new car. There were 3 or 4 other STis that all passed tech, so it's not a common problem. If it were it would have been found there at the event.

You have a couple options,

1) get it in writing that there's nothing wrong with the car and then bring it with you when you auto-x. Find the event chair (Chris Franson) if the lead tech doesn't accept it.

2) Bring it to another dealer and see if they see something wrong.

If it gets worse, then there's really something wrong.

This isn't the 1st time that a new car was available to us and "there was nothing wrong" Clutch shudder anyone?

Again.. there should be no play. If there is, the mechanic at the dealership should understand that... it's NOT normal.

The Tech guys at the NER events are pretty good at what they do. They do what every other SCCA region (FCSCC is NOT SCCA) is supposed to do for safety checks. The wheel test is for 2 things... one, loose wheels. Yeah, I've forgotten to tighten lugs, as many people have. The other is the Bearings... they can seize up under heavy load. If you can feel it by your hands, something's wrong.

NE was also one of the 1st SCCA regions to institute annual Tech for Solo-II cars with the understanding that those that did pass it would be diligient enough to check their cars before they run. (The lug nut thing was a couple years ago.. now I double check every time)

It's hard to tell if the Subaru bearing is really going with the car on the ground like that, in my experience of having two bad wheel bearings. They were fairly bad and doing that test you still couldn't tell anything was wrong. If the car is in the air and you take the brake/rotor off and try moving the hub around in other directions, you can more readily tell if something is damaged. I had one where doing the car on the ground test yielded nothing but you could easily easily see by moving the hub itself there were problems. The shake the wheel on the ground thing really didn't yield anything until the bearing was completely gone. :)

Subaru wheel bearings generally suck, I'm sure the tech has seen and replaced a few of them. Find out how the Subaru tech was testing it exactly.

Yes. I explained to him in detail how I tested and that I tried it several times with all of the other wheels and that was the only one that moved. He acknowledged what I said, then said he didn't know what to do because he couldn't find anything wrong. It's my first time with a new car dealing with stuff like this under warranty so I hadn't anticipated any resistence. Guess I should have known better. :rolleyes:

I don't know if he had the wheel off or not. The car is still at the dealership and I'm still at work. It's entirely possible that the lug nuts were loose. I haven't tested them myself yet and I haven't had any reason to take the wheels off. I'll check immediately when I get to the dealership and see if I can make the wheel move still. Of course I'll keep checking this to see if it gets worse. I really don't want to be driving down the road and have the wheel fly off.

I wasn't aware of year long tech inspections. Does this mean that once my car passes tech (without wheel bearing problems) that I'm good for the year?

Thanks for the info.

When you get the car back, test the tire again. It could be as simple as either something like what I said with the lugs, or the Ball Joint like Gary said.

What's at Devens this sunday???

I was going to the Saturday and Sunday events at NHIS if that's what you meant. I'd love for you to look at it though. I just talked to the mechanic again and he said he tested it again on the ground and he "felt the play between the front and rear tie rods" but nothing he considered out of the ordinary. It's certainly not anything I can feel when I'm driving the car....

Maybe I just need get to know my car better. Perhaps my car and I should take a long weekend in Canadia together......

I'll be the blue STi #40
mofugga 04-13-2004 05:36 PM

my money is on loose lugnuts. 2500miles is way too quick for a bearing to go bad, even if it is a subaru wheel bearing either that or this tech is really strong:lol:

In our region you have to have done the majority of the events the previous year to qualify for annual tech this year, so no novices/first year people.

There's a BMW event that you need to preregister for to attend (it's full). I'll be up at NHIS Sunday. Too far for a 2 day event with one of them being non-points (Sat)

See you sunday. I have the loud wagon. :)

Just for grins, you should insist that the mechanic go over all of the nuts and bolts for the suspension on that side of the car and make sure they're all at the proper torque. It's under warranty, it only does it on one side and it's a potential safety issue.

BTW: Here's the procedure for checking the bearings straight from the '02 Impreza FSM:

"E: Inspection
1) Inspect the rattle of bearing, give the tires a shake with grasping both the upper and lower sides of the tire. And also inspect to rotate the wheel smoothly."
<drawing of car on lift with tech grasping upper and lower sides of tire> :lol:

So, if that method doesn't work, Subaru need to come up with one that does before we have wheels coming off at autocross and track events. :furious: :lol:
614inda617 04-13-2004 07:49 PM

I just got the car back ( only 5 miles on it from the tech :)) and I couldn't make it move this time. Of course it's raining and dirty so I didn't try that hard. I'm pretty confident that there's nothing wrong with the wheel bearing after reading the tech's report:
[QUOTE][FONT=courier new]CHECK FRONT LEFT WHEEL BEARING FOR NOISE ALSO BALANCE WHEEL ON RIGHT SIDE. TEST DROVE VEHICLE FOR NOISE FROM LEFT FRONT. NO METALIC BEARING NOISE. THER IS RAOD NOISE FROM TIRES. RAISED VEHICLE ON LIFT AND RAN VEHICLE TO CHECK FOR BEARING NOISE WITH STETHISCOPE. NO INTERNAL NOISE IN HUB. CHECKED FOR LOOSENESS NONE FOUND. NORMAL STERRING PLAY IN STEERING RACK.[/FONT] [/QUOTE]

Seems like he was pretty thorough and since he's the one holding the stethiscope I'm just gonna believe that the bearing is OK. I don't like having any play in the steering, but I certainly can't feel it when I'm driving and I have to use a lot of force to feel it at the wheel.

Thank you all for your helpfull advice. This turned out to be a very pleasant experience for my time to the Subaru garage.

I actually had an over-zealous tech try to tell me that my battery wouldn't pass because I was using the factory VW method for holding it down; i.e. lip on one side, bolt and plate on the other (no strap). It had about 1/4" of play in it only on one side and only when yanking hard. He tells me that it could touch the hood and blow up if I flip; yep, I'm familiar with that concept. I pointed out to him that it was several inches below the washer reservoir and that didn't even touch the hood; the 1/4" of play wouldn't ever make it make up the 6" difference. He stood quietly for a second then started bitching at me again. *sigh* I told him I would go shove a pencil or something in there.

I then went to talk to our head SSS and the Solo2 chair; they were like "uh, don't worry about it." I'm much in favor of year-long tech although we don't have it. :(
eastcoastbumps 04-14-2004 12:59 AM

Sounds like you really don't have a problem. However I'll inspect it and road test it on Sunday if you want. :lol:

I wasn't told about this year long tech. KC, can you explain it a bit more? Who do I have to talk to? A novice drove the VW last week and may do so in future events so is it cool to have that car teched for the year also? Thanks.

Well, I beg to differ. Have you read the THSCC boards recently? :)

There is one in Danville on the 25th. Just ask Simoniac!! :)

DrBiggly 04-14-2004 10:51 AM

Brian,

Careful with assumptions...this was not at a THSCC event. ;) I realize that THSCC has year-long tech and I have Simon's email as well. I would believe that whomever was in charge of tech wouldn't be as unreasonable about doing tech. I hold THSCC to a higher standard.

I should have specified that I was at a SCCA event in the previous post. Oops!

614inda617 04-14-2004 12:08 PM

To be clear, since it seems like people are ripping on tech's a bit, I don't blame the tech at all for requiring me to get the car checked out. I think it's great that guys volunteer to check out all of our cars to make sure we don't kill ourselves or others. It has to be hard to be an expert in how much [QUOTE]STEERING PLAY IN THE STEERING RACK[/QUOTE] to expect in every car. If my car moved more than the other STi's then the tech had a legitimate concern. I'm sure most of you guys are just poking fun at the tech's but I just wanted to be clear that I'm not making fun of them. :)

I bet that was exactly it. Seems to be the last things some techs look for. I traded in an Audi S4 and hastily swapped over from my aftermarket wheels to the stocks for the trade in. Well, just a bit too loose and noticed by the used car manager. He came back 45 minutes later saying that his ACE mechanic says it's either bearings or a bad rear end or bent axle. This ACE never bothered to check the lugbolts. I tightened them and the problem magically disappeared.

I bet it was one or more loose lug nuts.

About two weeks ago, I switched my Evo back to the OEM "summer tires" and noticed while putting on the left front tire that two of the lug nuts were not behaving well. By this, I mean that they would make loud noises while tightening -- almost like the "cracking" or "clicking" of a torque wrench -- but these noises weren't from the torque wrench. But I torqued all the nuts to spec and convinced myself everything was okay. The next morning I took it to a local autoX and did my own "pre-tech" inspection and discovered play in the left front wheel. I jacked up that wheel and removed it, inspected the studs and the nuts, and put the wheel back on, being careful to tighten it down methodically and slowly in a star pattern. Again, the "clicking" noises from the lug nuts. I tightened the wheel down -- unfortunately without a torque wrench -- and lowered the car, and still felt like there was some play in the wheel (but a lot less). The car passed tech and made it through four runs okay. But I'm not going to use those lug nuts again. :(
614inda617 04-15-2004 12:50 PM

Hmmm. This will be interesting. Since it's a little drier today I'll test the wheel again and if there is still play I'll losen and retorque all the lugs. It'd be great if that was the real problem!

A Subaru tech/autoxer told me that the noise that sounds like wheel bearing flop on my car is actually the parking brake shoes slapping inside the hub. That was almost a year ago, car is no different now 20k miles later. YMMV
