Ive got 97 sc 300 rearend shaking after car reaches 20 cv joints feel tight was told it could be stablizer bushings not sure money is tight any one know were I can get diagram of rear end or any idea what can be

 

it could be a lot of things... when does it happen? is there a time it doesn't happen? Freeway, road? speed dependent? or at all speeds?

 

Are your wheels balanced? Or are your tires out of round or belt seperation? Rotors maybe warped. Bent wheel. Driveshaft guibo or center support bearing. Diff bushings. Alignment.

I doubt the stabilizer bar would cause this. It might make a noise but won't cause vibration. Especially going straight. I would also suggest tranny mount.

These are just a few suggestions to check out.

 

if its speed related then it might be the rotors warped or tire balance
same thing happened to my friend in his S2K

his rear kept vibrating after 60mph
balance the rear tires and it was gone

if the rotors are warped
go somewhere where you can drive straight at 40-50 without stopping like a highway
maintain that speed....and slowly raise your E-brake, 1 click at a time
if you feel a vibration or pulsing on the handle then its the rotors

 

Remember, our ebrake is a drum type so that won't do anything. I'm sure most shops can put it on a lift and check it out for free.

 

check the drive line bolts
