Bad Driveshaft U-Joints?
Hello everyone, so for the past few months I've had a high pitched squeaking sound coming from the rear of my truck. It only occurs under acceleration when the truck hits the slightest little bumps and changes in the road surface. Speed is not a factor but it is harder to hear when going faster because of wind, road, and truck noise. Could it be u-joints? leaf spring bushings? The shocks are 1 year old so I doubt its them.
Its progressively become worse and is getting very annoying.
I just fixed my squeaky brakes and leaking steering box so now this. Thanks Dodge

Grab the driveshaft while its in park and turn it back and forth you should be able to tell that way...my driveshaft will not move at all when in park but i did just do that ujoint about 9the months ago...
If you do change it get a greaseable ujoint...got mine for $11 and took me about half hour to change

squeaking is usually how they start, then it can progress into a click.
as said, test by twisting the u-joint back and forth. ANY movement is bad. also visually inspect the seals around the caps. should be intact, tight, etc. if nothing obvious, stick a large screwdriver through the cross and pry back and forth with a little more leverage. any movement indicates it needs replacement.
+1 on greasable, but i recommend the more expensive Precision brand Super-Strength greasables. they're more expensive at $20-30 but worth it.

Thanks everyone. I figured it was a u joint. I believe its going to be the front driveshaft u joint because the rear u joint was replaced already after I blew it plowing over a big snow pile in reverse.
