vibration in rear end.

1997 chev c1500 i had a real bad vibration in the rear end so i replace the carrier bearing and u joints. the vibration is less than before but it starts at around 60km/hr and increases at higher speeds. i can feel it throu the pedels and slightly in the stearing wheel could a tire be outa ballance or is my diff goin. it doesnt houl. it used to befor i replaced the u joints. Any ideas would be great. thanks

my e-brake cable is hangin. like its extremely loose. so is it possible that my brake is on. causein it to vibrate.

Vibrations at 55-60 MPH is usually tires and wheels.

Any noise besides vibration?
E brake usually does not vibrate.
To check for E brake cabble sticking jack it up in rear and apply brake and then release it and see if you can turn wheels by hand without drag.

Swap the tires front to rear and see if the vibrations transmit through the steering wheel. If so it's defintely the tires.

there is no noise. in the cold this mornin it seemed to hesitate once i put it in gear. should i get the trans. flushed while im at it.

No on flush.
You can flush up more problems than you flush out.
How many miles on transnission and when was last filter service done.

With that many mile it is dangerous to do anything to it.
Is fluid level good hot in park?
I would just check filter and not even use much new fluid.

so the truck shifts fine once warmed up. and i jacked the truck up the noticed the driver side brake was rubbin. so i took the tires off and hit behind the drum hopin to free them up. now the vibration isnt as serious.
