My 1992 sc 400 virbates severely at 70 mph, suspecting the Universal joint in the driveshaft, but my local lexus dealer says i can only buy the whole shaft assembly with all the seals and center support bearing for over $800. where can i get just the universal joint?

Are you sure its not a wheel thats out of balance. You can not notice a wheel out of balance until you get to a certain speed. Does it stop after a certain speed also? What makes you think driveshaft?

it only vibrates from about 70-75, i think it is not the wheels because the vibration changes depending upon whether i am accelerating or coasting with no throttle. The tires are badly worn and i will be replacing them anyway. at the moment i am considering the driveshaft replacement with center bearing from driveshaftstore.com for $397.00. Lexus wants over $800. Any suggestions?

its most likely your trans mount, and possibly your motor mount also but more the trans mount. try change it first its only like 60 bucks and only takes like 20 min to change.
