bad vibration in drive train

[speedfreak]

my center bearing and rear drive shaft have a real bad vibration at about 30mph, im wondering if my center bearing is worn and if any of you have had similar problems? everything seems to spin well from the center bearing back if i disconnect the rear propeller shaft. any ideas?

Does it make a "clunk" noise during hard acceleration?

 

[speedfreak]

not really it makes a little noise like the propeller shaft is hitting something around it at about 30 but otherwise it just vibrates

Check the Uni Joint phasing by sighting along the shaft to see if they're all in line.

I had the same problem after I install a cusco chasis brace. The drive shaft change will help, but I think what fixed for me was tranny mount. I replaced the new mount and the vibration went away. I also had synchro on the car replaced which now works like new. :1zhelp: :1zhelp: :1zhelp: :biglaugh: :biglaugh:
