making a loud clunk/sounding like something snapping. when i rotate the drive shaft with a wrench it makes a similar noise but not as lound comming from the rear end. any clues. i replaced the read ds u joint when i first got it, and i thought it was maybe the front ds u joint but i further inspected to find this. any help is greatly appreciated.

 

there is some play in the shaft when i tried moving it by hand. also between 45 and 60 mph there is vibration comming from the rear of the truck.i replaced the diff fluid when i did the one u joint and found a small chunk but that was over a year ago and it ran fine until now. hopefully its nothing major, i cant even afford the lift and tires i want. college is eating all of my money

 

Do you have the limited slip differential? I've seen a lot of people on here talk about problems with that breaking.

 

Some drive shaft play is normal.

When you shift from R to D are you stopped or still rolling?

 

Oh, and you found a chunk of what and where?

 

yes on the lsd. and im stopped when i shift. i can hold my foot on the brake and go in to D then R then D and when i put it in D i hear it. and it was like a half moon looking thing of metal.

 

C clip. Take your truck in for differential service, hopefully it is not to late.

 

By they way, if your truck is a 02-05 and has less than 70K it should be covered under warranty.

 

****, another one bites it. don't drive that thing around without taking a look at that diff first!! you might have caught it soon enough, don't ruin it.

 

ha i can barely afford to eat, im going to have to driveit because work is not within bike riding distance
