I searched a bunch and see that a lot of the clunking while braking is either trashed diff mounts or missing/broken retaining clips which im pretty sure isnt the case.

I just got my car back from inspection (had to have new wheel bearings put in and DTSS eliminators put in due to toasted bushings) and it drove fine for maybe an hour then i hung out at home for a bit and decided to grab some lunch.

On the way out of the sheetz parking lot my right rear tire got in a bit of a pothole somehow. Looked about 3in deep, it sucked but i thought nothing of it and kept driving. Well then i came to slow down to a red light and clunk clunk clunk or maybe even a loud tap tap tap whatever it was I didnt like it so I got it home took the wheel off and all the clips are there brake pads are good (just passed inspection today!) and I highly doubt any mounts are shot due to a pot hole even though i guess anything is possible, wouldnt it clunk while shifting?

So im confused/pissed not sure if something happend today or if the mechanic that took a month and a half to put wheel bearings and DTSS eliminators in and inspect it fucked something up.

I dunno im gonna go play with it see if i can figure it out. Any help is appreciated

Thanks
Matt

I'm not sure I would trust any mechanic that takes a month and a half to do those things... other than that I'm not sure what to tell you.

yea i wansnt to happy, in the future ill find another mechanic but ive never really had to take my car somewhere to get something done and my grandmother insisted i take it to her mechanic, later on i found out he runs a four bay garage and a dealer ship between the wife and himself and my car was one of thirty sitting there but either way i was pissed.

I just noticed the rear driverside wheel (one making noise) has a bit of play like pulling pushing on top and bottom of the wheel (side to side its firm) but does that indicate the new wheel bearings arent in there so great?

yeah that sounds like wheel bearings (but I could be wrong). it's possible they were done wrong or not done at all. you never know with some shops, or maybe they made a mistake, but doing bearings wrong/not doing them would be a nasty mistake.

if you're concerned that it's your bearings take the assembly apart and inspect it.

eh.. im not concerned i know there are specs for the play in it and i think its alright

just took it for another drive though and if i lay on the brakes it doesnt really do it and if i hit them softly it doesnt do it. It seems to only do it when im slowing down for a stopsign or a light and now that ive experienced it again i could almost describe it as catching something and i think i can almost feel it in the pedal.

Floofin7 - Remember, all wheel bearings are supposed to be re-torqued after about 50 miles or something.. .maybe your pothole experience caused them to need it a little sooner?

Off topic, where are you at in Bellefonte, I live in Bellefonte too! Give me a call some time if you want to meet up, 570-974-1786, my name is Aaron..

Cheers!

hey whats up Aaron i know, im the kid from autox, Matt, Ive been trying to come but as you can tell i just have problems after problems with this vert,

I figured it might be loose due to the play in them so i tried to tighten them but I cant budge the nut. Im taking it back over to the guy tommorow hopefully he can press the bearing in tighter or figure it out ive been playing with it all day and i cant seem to find anything else it could be other than a loose bearing. And im not sure if the pothole knocked it loose, youd think that it would screw up the side that hit the hole instead of the opposite side.

Off topic....I see in your sig you bought an rx-8 man did you get bored with your porsche already if so feel free to throw it my way or is the rx-8 your "respectable daily driver" or will it be autocrossed?

Thanks for all the help guys

Oh, hey Matt! Sorry, didn't realize that was your handle!

What mechanic did you take it to around here?

Basic troubleshooting for a problem like this, though:
start with the wheel, does it have lateral movement (in this case, yes) NEXT
put the rear end on jack stands, take the wheel off. start shaking the assemblies until you can figure out where exactly the loose link is. Basically, it has to be either the bearing itself or one of the three support points. Anything else really can't cause a vibration in that area.

If you need a hand, lemme know, I can possibly stop by sometime soon to help you out. At least let us know what the mechanic says...

And yes, I got bored with the Porsche... It's just not as much fun to drive as Mazdas, so I decided to pick up the 8 before I get married next year and won't have the money to do it I'm selling the box, but i'll be autocrossing it this weekend. I will have the 8 out at some point for fun, cause it's an awesome handling car, but the TII is going to be my primary race/fun car..

Did you check all 3 camber links? The toe links? Usually when you smack a curb hard it screws up the toe link, maybe it's that?

Hey i had something similar happen when i decided to take a corner at a crazy speed, it ended up being a broken sway bar link, check that if you havent already.

Yea this is the first thing i did and everything is nice and tight thats why I decided to ask the 7club, Ill go over it again this morning before i drop it off and check out everything mentioned by everyone. (Thanks! appreciate it.)

Aaron- i took it to Holtsingers, i believe its it called that, if your going up the benner pike out of bellefonte on the right theres a big sign saying Progressive Auto i think (thats the dealer) and next to the dealership theres a garage with a sign saying holtsingers.

Oh and i stopped by the guys garage last night after messing with it for a few hours and explained the problem, and he asked if i was sure there was lateral movement and i told him it deffinetly had some and he said yup prolly wheel bearing, drop it off tommorow.......hopefully this wont be a week long deprivation of my 7 to tighten a wheel bearing or even just look at it.

Also congrats! on the marriage Aaron, and i forgot about that Tii you have.......guess im trying to block it out becuase i cant believe you got that thing for so cheap

Just checked everything again, nothing is broken and everything is tight. Also a little suprising i didnt know the sway bar link was plastic kinda weird, but everything is in order so either its something else inconspicuous (sp?) or the guy f'ed up the wheel bearing.

Say he did mess it up would it be as easy as pressing it in right/ tightening maybe or would this have trashed the new bearing? I hope not.

Dropped it off friday picked it up saturday talked to him today.

He said everything was tight and in place nothing broken or out of spec the only thing he said he could say was that my rotors didnt pass by very much and they didnt look to great along with needing new brake pads soon as well could be my problem.

My rotors look a bit crumbly towards the very edge but i didnt think that would affect anything being right on the end but who knows. Any ideas?

Im probably just gonna get new pads+rotors all around and see if that does the trick since it needs them anyway.

Thanks

sounds like he's pulling the typical stealership "well, that problem is fine, but you have 20 other things wrong" line

I know this has been pretty much covered already, but have you checked the torque on the 3 bolts that locate the rear hub? I don't remember off the top of my head, but it seems to me the DTSS link, for example, should be torqued to 80-90lb/ft - similar to wheel torque numbers. Beyond that, check the upper strut mount, and general condition of the strut - if it's leaking, that's a definite bad, but it can be blown internally and not leak (which could have happened in the pothole); it could allow undamped wheel movement that could cause clunking. Try bouncing that corner, see if you get any noise; and when released, the car should rebound upward, overshoot the normal resting height slightly, and settle to the resting position - more oscillation than that indicates a worn/blown strut strut.

There really shouldn't be any play in the rear wheel bearings - I'd check the bearings out regardless.

Yea i wouldnt be suprised, but theres not to much i can do about that, some day i will have all the tools i need and be able to do the simple hour long things that started this fiasco (weld exhaust leak, press in wheel bearings). I actually did pick up a welder in the month and a half he had the car so that takes care of a few things.

rx7racerca - I also had the idea it might be a blown strut but since it was only during braking and not turning (and my right wheel hit the pothole instead of the noise making left) i threw that idea out but I just went out and checked like you said anyway and both sides react like they ought too and no leakage.

Thanks for the input guys

~overdose~

it weird this happened to me once a few weeks back and it never happened again but i never hit a pot hole of any kind an i checked all 3 camber links and looked over the toe links everything is good it left me scratching my head....

Lizo7

iTrader: (11)

Okay so after driving a bit more and checking it once over again im starting to lean towards rx7racerca's strut theory, im not so sure how hitting the oppposite side could mess up the other side. but if i press with a good amount of force down on that side it does seem to creek some and not on the other side. but like i said before the rebound seems to be fine.

overdose- sweet, wish mine would go *poof* as well

I just cant believe the "mechanic" was just like hmm yea im not too sure. Your supposed to be a mechanic
