I had a vibration only around 25 mph and when I had a load in the truck, I had no vibration. So I thought it had to be the older u-joint (replace one already two years ago).

I had the truck in for inspection and had the shop change the u-joint. It fixed the vibration at 25 mph, but now I have the faint vibration at higher speeds that I didn't have before. The vibration is typical rythmic sound that you hear when a u-joint is going bad.

Any thoughts or ideas what might be causing this? Bad u-joint, bad instalation? Thanks

did you just replace only one joint?


imo, it's good to do em all at once...

at least, that's the way I do mine...

have you got underneath it yet? check to see if the shaft is in phase, they might not have put it back right. You can try to rotate the rear tires to the front to make sure it isnt a tire issue.

Yeah check the phasing:

oh wow yall, I completly overlooked that and forgot about that when I just did my u-joints last weekend...

looks like I have a little side project for Sat now, lol

might get rid of some of the vibration I'm having right now; thought it was all my rear bearings cause I know their in need of replacement, but we'll see when happens
