Weird Squeak?

[AntleredRuin]

I recently had a squeak in reverse, too. (99 3.4 2wd).
Found out It was the rear u joint (the one at the rear axle). It would barely move by hand with the driveshaft removed.

I wound up replacing the entire driveshaft with one from a junkyard 97 for $50. He'll of a lot easier than banging out old rusted ujoints, and a whole lot cheaper than paying a shop. According to the ODO, it had nearly 70k less miles than mine.
Now no more squeak, less vibrations, and no thunk when letting off the gas at freeway speeds.

Hi All,

New here, and don't know how all of this works but I have the same squeaking issue on my 99 limited 4wd. My mechanic confirmed that it was the ujoints, and it sounds exactly like what everyone is describing.

At first he quoted me 250 for the parts and labor, but did mention that there might be a possibility that the ujoints are the ones that you cant punch out, and it will escalate the scope of work. He just called me back and told me that is the case and it would be 1100(!!!) just for parts.

I can't find anyone on here that has had ujoints that are not replaceable, and that had to change the whole drivetrain to repair. Does anyone know whats going on? Are there more than one type of ujoints that were made for the 3rd gen?

Don't you have grease zerks on your u-joints? My 96 and both 97's do.

Check the following. The rear driveshaft where to bolts to the axle. Make sure hose bolts are tight. Check your rear UCA and LCA bolts and bushings. Check your body mounts. Try and get under the truck while someone pushes on it up and down and see if you notice anything odd.

Not sure, since I wasnt able to get under the car, but I will check. Is it possible that it just needs a little grease?
