well a while ago some of you may remember i posted about a wierd sound when i let the clutch out...

well now it seems to just happen really freakin' randomly...

i should say i usually here it on start up but i hear it other times too just randomly....annoying!

its a deep groanish type of "squeal", but not really a squeal

sometimes its worse than other times...louder, or longer in duration

i was thinking wheel bearing possibly? so yesterday i took off all 4 wheels sprayed some wd-40 around the axle bolt...(middly of rotor) and also behind the rotor and hoped that it would seep in...

after that sound is still happening...maybe it just didnt help though?

also another annoying thing is that no matter what i do it seems like i cant get the sound to happen when i try to...ie i wanted to show a friend and it didnt happen...so basically its really hard to have someone stand outside and have them listen to where its coming from cause it doesntt happen consistently...but it does happen a lot...

what do you guys think...is their a way to test wheel bearing without tearing everything apart...or should it try and test other things?

thanks!

bump!

its been a while, no reply so "bump"

btw i accidently hit a curb and effed up my alignment, had my gf's dad take it into their dealership to fix the aligment and noted that, so their going to take a look at it...

any ideas that i could pass along to them...right now were kinda scratching the surface with ideas...its a hard sound to recreate when you want to so you cant have someone outside listening for it...unfortunatly...

anyone?

Check your motor mounts... I have a squeal every once in a while b/c I have 2 of the 3 being aftermarket...

it has nothing to do with ur light flywheel?....i know some brands in certain cars tend to rattle at idle...i mean i know u said "squeal" but im just throwing stuff out there...does it happen when driving and at a stand still?

hmm maybe brakes or rotors? depending on when they are warming up or allignment of your pads?
not the timing belt?
sorry im not sure

I didn't know you had a LWFW.
OK lets theorize for a moment. The factory FW has a Iron surface for the clutch disk to "grab" and move the car. The LW has an Aluminum surface for the clutch to "grab". Iron has longer ware properties than Aluminum and better distortion properties vs heat.
So knowing that I would have to guess that the clutch disk is wore to a point there the pads are virtually gone.

But from the sounds of it, your issue is in that vicinity any ways, T/O bearing possibly. So while your in there have a look at the FW surface and clutch.


You did buy a "sprung hub disc", didn't you?

to try and answer all of your questions...

1)factory motor mounts (waiting to put all three vf in!)

2)the flywheel does chatter quite a bit, but like you said chatter isnt squeel...i wouldnt think it would be the flywheel but who knows...not me!

3)brakes and rotors are most likely i just put in centric rotors and mintex pads all around...didnt know they could be misaligned...ill note that to the shop

4) back to the flywheel, again it could be a problem with the flywheel/clutch...but why would it all the sudden happen after a yeah ya know...cause the clutch shouldnt be dead after a year, so its wierd that it would start to squeel after such a short period of time..

thus far ill have the shop check out the brakes...(cars their anyways!) and hopefully they will find something!

oh btw. more ideas are definatly welcome here!
