I have balanced and rotated all the tires.... would a bad LSD cause the vibration??? the car only vibrates when past 60 mph and only when accelerating or when foot is on the gas.. it does not vibrate when coasting over 60mph.. it really start to bug the **** outta me.... any help would be greatly appreciated.....

next step is to upgrade axels to a newer and stronger set....

 

your wheels may be bent

Jeez... lower ball joint? CV joint? axle?

When did it start, all of the sudden or gradually?

 

all of the suddden... for about a month now

 

Mine is also beginning to shimmy under accelaration and braking - would be very interested to know what your problem is!

 

Same here. Except I feel it only happening on my left Front. Happens on acceleration and is more pro-nounced when accelerating out of a corner ...
Sometimes I feel it happens on deceleration as well ... (could be getting paranoid)

I started a thread thinking it was the steering, and i've checked everything for freeplay....
- alignment
- camber
- wheel balance
- corner balance

I'm starting to think it's my Diff or something mechanical, coz I think it started happening, after a track day, and I was not concentrating, and kept banging my clutch out when I was heel toeing (not matching it correctly) ... bang'd it all day long then everything started to feel weird

I use an ORC clutch, so engagement is pretty sudden, so think i shattered something or flatspot something in my LSD.

I'm pretty tempted to have it pulled apart but unfortunately, i gotta pay someone for that

 

You guys check your wheel bearings?

 

If you have an extra set of wheels and tires, I would suggest swapping them to see if your problems go away. That will narrow the problem down by determining whether it is something in the wheels/tires (balance, bent, etc) or something in the rest of the car.

 

Mine does it on two different sets of wheels for sure

16x7 - dunlop dz101
and the OEM wheels with semi's

are there easy ways to check the wheel bearings/lowerball joints/cv's?
