Topic: driveline virbration...rear end?

[NWFshrman]

so when i get up around 50mph i start feeling rear end vibration... every once and a while the rear end will "shake" when taking off turning and  or "pop"

the rear end is welded...not sure when maybe 3rd member?

If it's your driveline  making the vibration take it off and check the u-joints or just have a driveline shop replace the u-joints.

I have never ran a welded rear end but maybe your tires are off balance or un equaly worn or you should check the tire pressure. Just some simple ideas.

I second what swapped89 said about having the u-joints checked out. If you would like to look at the joints, grab a flash light and visually inspect the u-joint. Try to move the driveshaft back and fourth up and down. There shouldnt to much play and the caps shouldnt wobble around while inspecting. Good luck.

If so, most U-Joint shops can do the work in a day or so for around $50 plus U-Joints

I had similar symptoms that ended up being a seizing u-joint. I did the visual check for a sloppy joint and they looked ok.

I finally pulled the rear drive line and drove in front wheel drive and the vib went away. One of the u-joints was so tight I could not move it by hand.

definitely have your ujoints checked.  with nothing in the bed of my pickup it has vibration when taking off from lights and turning with a welded rear.   never had any vibes at speed tho.

I had that same problem I did the joints then turns out it was the wheel bearings. If yer located around Gresham sandy or Portland Oregon I know a guy that does it for 50$ a side. If u supply parts. He's a way cool old timer. Been doin this stuff for years
