Is it clutch chatter?

replaced the engine mount bushing with a new one and while the vibration has been reduced and i can barely feel it anymore it's still there at around 36mph in any gear, any rpm. the new mount is nice though.. everything is night and tight now.

brakes are fine, just replaced the front rotors and pads this weekend (wooo hooo!! new brakes are AWESOME!!) and i also checked CV axles. no play in them except for the movement left to right between the wheel and the transmission but i assume that is completely normal.

i'm running out of ideas guys.

this is coming from the back somehow.. could it be my rear tires that are on their way out? they are pretty much worn down to the legal limit but i was gonna ride on them for a while longer, the wear is very even and it doesnt really rain too much this season here in FL so i feel safe enough.

maybe the wheels need to be balanced/road force tested?

If the vibration is speed related and not engine / transmission revs related, then it has to be caused by a wheel / driveshaft rotational problem. Changing engine mounts, clutch flywheel or muffler brackets won't help....

I would hazard a guess its your worn tyres - as a quick (free) trial, swap the rear wheels to the front and vice versa. I know the wheel sizes a different, but it may give you a clue to the problem, especially of you can feel the vibration through the steering wheel instead of the seat of your pants.

i'll stay on it and report back.

so the vibration I was chasing for a few months was because of the front tires.. ugh!! I just got some new shoes on the front and no more vibration at 36mph.

case closed!

cheers,

Good for you. Must feel great to finally resolve a nagging issue.
