Bad Axle Shaft U-joint Symptoms?

I'm wondering if I have a bad passenger side axle shaft u-joint. I've had a bit of steering wheel wobble especially when I make a sharp right hand turn and sometimes to a lesser extent, with a left hand turn. That and I get an intermittent sorta dry wobbly squeak that seems to go away when everything gets warmed up after 15-20 minutes driving. Does this sound anything like a u-joint? I ask because I notice that when I turn the driveshaft I get a bit more slop and turn of the front u-joint and shaft on the passenger side than the driver's. This is maybe 1/2" vs. 1/8" of movement. TIA

Are you turning the shaft or are you moving the ujoint up and down and side to side? If there is movement in the ujoint up and down or side to side then replace it. Could also maybe your wheel bearings.

You are the average of the five people you spend the most time with.

I have this as well, only when turning though, either direction. I have completely rebuilt both drivelines so that aint it. I'm going to start on the front end next. I have a little over 100k on it and the front end has only had fluid/brakes type maintenance. Probably time for wheel bearings, axle u-joints etc. Any suggestions for myself and the OP would be appreciated.

I'll try to move the actual u-joints today. I've done the old try to move the whole tire and wheel to check for ball joint slop and there's no movement there. I confess that I hadn't thought about the actual wheel bearing itself. Though maybe I'll jack up the front end and try to see if I have any roughness there.

I checked them today. I confess that I hadn't actually thought of the wheel bearings before now, though they turn freely and with no real grinding or resistance. The axle shaft u-joints seem good, but how much play is too much. The driver's side doesn't budge really at all. The passenger side turns back and forth barely at all, like about 1/16th". (edit) I should have said that its not a an up and down or side to side movement, but rather just a rotational movement.) Is that too much? Are u-joints known for producing any other tell-tale signs as they get bad?

Make sure all ur zerks are greased up i.e. tre, and ball joints. Also check ur steering shaft u joints.

Yeah, everything is greased up, and while the TRE's are in good shape, I'm going to replace them soon as they boots are torn and ooze grease frequently. The driveshaft's u-joints seem to be in good shape too, so that's why all of this is confusing. :?:

i would think that if you have that problem only when you turn, the problem is in your outer u joint.
wht ever happened with this?

Still working on it. Just pulled the shaft today and working on trying to get the u-joint out. Trouble is, the outer shaft, old u-joint and inner shaft are all so rusted up from where they're exposed to the elements that I can't even seem to find the c-clips holding the joint in place. Any suggestions?
:EDIT: I should've said that I figured that it's the driver's side because when I lifted the front end on jacks in the air I got binding when I turned the wheel full lock (either right or left...) and spun the wheel. Now that I have the shafts out, the u-joint seems to move with no resistance. Is it bad? Dunno...
Figures, I thought that I'd have more trouble with removing the axle nut and/or the unti bearing, but they were a breeze, even all rusted up.
