Rear End Virbrates Pretty Bad?

[Symba_The_Lyon]

Hello Im sorry i haven't been on a lot lately but anyways, My problem is when i go past 25 mph and and i take my foot off the gas pedal the rear end starts to vibrate the entire car? But it stops as soon as i give it gas it quits? Any ideas? and another thing I been wondering is i have noticed is when i'm driving and i come up to a stop light and do a complete stop it sound like the rear end drops to the floor? Any ideas bought that?

inspect the entire driveshaft for play in the joints any front and rear yokes if nothing is found remove the cover on the diffy and inspect you gear teeth and wear pattern.

I just recently went through the same thing, ended up being the u-joints. The rear axle was really heating up though, so I also replaced the rear diff fluid as well, just to be safe.

So you guys when i inspect the rear drive shaft for play, am i look for play wile trying to rotate the rear drive shaft buy hand? Because i know i can spin the drive shaft wile it is in park just a little, is that normal?

that is normal for the driveshaft take it and shake it back and forth and side to side to check for play in the joints or yokes.

Ok so i have tried to wiggle the the drive shaft back and forth and it is hard as a rock and i also checked the drive shaft after a 20 min drive and is was cold as a rock, LoL I will be checking the teeth in the diff as soon as i get paid again and ill let you guys know how that goes, I was thinking not changing your rear diff fluid for 20 years that would make it vibrate would it?
