Strange Shudder Feeling

[bighammer]

My 03 is having a fairly high frequency shudder and I was guessing I had a bad U joint in the driveshaft. I jacked a rear wheel up and gave it a spin and it went very smoothly and easily and the joints appear to be fine. (I greased them again anyway)

It seems to be most noticeable when coming to a stop. It comes at about 20mph and goes until I stop. Pushing the clutch, coasting in N, or in gear doesn't seem to change it.

Should I drop the shaft to examine the joints more carefully? Maybe something in the diff? I would guess it's about the driveshaft speed

I might take it for a short drive and see if anything gets hot.

OK, where's that light bulb smilie? I forgot the front shaft turns as well in 2wd. I think I know what I'm working on next... .

Jacked up the front and all seemed smooth there.

I took it for a drive because it seems to get worse after I get 10 miles or more on it. I crawled under and all was cool up front, but one cap of the middle joint in the rear shaft was really HOT.

Glad to know what it is. I was worried it was axle or trans.
