Replaced Guibo & CSB. More issues.

[lonestar22]

i was getting some nasty vibrations so i replaced my guibo disc and my center bearing. both in which were completely shot. about a month later, the problem is back. any time the car is underload there is a nasty loud banging. as if the driveshaft is hitting the tunnel. do i need to replace my driveshaft? could a bad tranny mount cause this?

In almost all cases, a failure of the CSB will be the result of binding u-joints in the drive shaft. While you might gain temporary relief from replacing the CSB, the new CSB will have a short life. The only real fix is a new or rebuilt drive shaft.

Worn transmission (and/or motor) mounts won't cause the vibration, but they will magnify the affect. If they haven't been changed in a while or are original, definitely replace the mounts (and the differential mount if it has cracks).

well i noticed there was a tear in the tranny mount when i first replaced them. so thats for sure getting replaced this time around

I went through the same thing you did. You need a new driveshaft.
