Unknown drive shaft problem

[saxguy09]

Ok so I installed a new CSB yesterday on my car, the old one was destroyed. The previous owner had currently installed the guibo, tranny mounts. I check the u joints whilt putting in the CSB and tthey were good. I drove about 50 miles or less today and the brand new CSB failed. Any ideas on the source of the problem??

A failure of the CSB is almost always the result of binding u-joints in the drive shaft. Replacing just the CSB may gain temporary relief, but the news CSB will have a short life. The only long term fix is to replace both the CSB and drive shaft.

Does your car vibrate under power? you can usually tell a bad u-joint from the drivers seat.

the car only vibrates under moderate or heavy acceleration when first pulling out or going up hills. The shaft is hitting right under the e-brake handle

Time for a new DS. Stiff u-joints are a BAD thing not a good thing

yeah, it's new DS time...seriously!
On both my e30's I've replaced the DS's. I totally got rid of any vibrations caused by bad joints (usually occurs to the rear joint first).
