Oh, the hard to diagnosis Noise.

Actually, I have this "Clunk" comming from the rear under the following condition's;

Movingin slowly, on and off the gas, the clunk occurs when the driveline is unloaded.

Upshifting, Auto, 1st - 2nd clunk, drive line loaded.

Coasting, Clunk, Driveline Loaded, Unloaded.

Now I think that it a loose u-joint, but I have not checked, (Manualy tried to twist the drive shaft in park to check for Play.

Truck has 1800 Miles, has done Light Towing (1200 Pounds Max). But I heard the Noise before the Towing.

It's not getting worse. But it is noticable.

So,
When I check the Drive Shaft to see if it twists, should it move at all? If so, how Much?

How can I check the rear diff?

Any Ideas? Or is it just Normal?

3.73, Auto, Limited Slip.

Check your carrier bearing! When mine went out it was a pretty hard one to find!! As far as your u-joints go you shouldnt have play at all! Sometimes they are hard to find by hand but what you can do is drive it 4 a while and work the driveline pretty ruff such as a bunch of stop and go where you are upshifting and down shifting and feel all the U joints most of the time the one that is bad will be a lot hotter than the others!

Hope this helps!

 

Uhh,

What and Where is that?

Carrier bearing or center bearing!

It is halfway down the drive line mounted to the truck with 2 bolts and the driveshaft goes through it. Almost in the middle between the tranny tailshaft and the front of the pinion!

No problem at all! Hope you figure out what it is!
