Replaced my axle u joint last year with some greasable ones

Recently has an alignment done and the guy at the shop told me my axle u joints has some play in them. He showed me, while the jeep was jacked up, using a bar to move them up and down that the joints could move around.

Does this sound like the right way to check an axle u joint? I'm wondering if that's really accurate to show play in them? Just never heard of it being done that way, always heard about checking them by turning the wheels when jacked up.

 

You sure he didn't say your ball joints?

 

Changed my axle ujoints a few months ago now I'm starting to get a noise under load in 4wd. Checked the ujoints yesterday very slight movement I think might be normal.

 

Nope, definitely axle u joints

 

Find a different mechanic and have him check your ball joints, then.

 

Will do but...he wasn't moving the while axle C he was moving the axle u joint itself

 

Oh, okay. Disregard. I misunderstood what you wrote. Still, might be best to have another mechanic check your U-joints.
