Hey everyone. Im working through some needed maintenance on the Buick, I replace the motor mounts last week, the ones I had were terribly rotted. Next will be the transmission crossmember and mount. Ive got my sights aimed on the drive shaft next. I ordered a center support bearing and will be replacing all the u-joints. Looking up the correct u joints has been a little troublesome. Are all the u-joints the same for replacement? The parts websites are all over the place in descriptions of what joint for what section of the drive shaft. Mine has a total of 4 u joints, one in the front, two at the CV and one at the rear. Thanks!
