vibration

i have a question im getting vibration in my rear when i push on the gas pedel it gets worse the faster i go does that mean time to change rear end

sounds like a Universal Joint to me.... I just replaced mine, dont try to do it yourself unless you have a good vice and ball peen hammer!!! If its not the U-Joint, its most definately your drive shaft, etheir its unbalanced or bent, hope its unbalanced other wise you gotta replace it. Good luck!

I would also check the Transmission mount and make sure it is not broken and caused transmission to shift a little to either side, this would also cause a vibration.

i have replace u joints after u joints thats not my prob its been doing since i put my different rear end in because the old one didi the same thing and my mechanic told me that it was time to replace it affter all it had over a 150,00 miles on it this one has been doing it ever since it got put in you think i might have an unbalanced drive shaft tranny is new too

it could be the carrier bearing or the rubber that houses the bearing, i just replaced mine and it fixed it. wiggle the drive shaft the rubber and bearing should not move
