vibrating from drive shaft

[mike991]

i recently fied my u joint it turns out the three bolts fell out so i replaced them, but now there's a vibrating noise coming from sort of the middle and back of the car. it only vibrates when im at high rpm's and in 4th and 5th gear.

any ideas on what this might be?

It seems you have this already figured out, you have to go back in there and do it again. GL

what do you think the problem is?

Could be any one or more rotating components. maybe some pics?

Check U joints first, then center support bearing/peload and collar nut tightness. The Gubio, associated fasteners and alignment bushing. and last, the drive shaft itself.

In almost all cases, a failure of the CSB will be causes by binding u-joints in the drive shaft. You can replace just the CSB and gain temporary relief, but the only long term fist is to replace the driveshaft. Rebuilt drive shafts, like those from Drive Line Services will come with a new CSB.
