U Joints

well, just greased a couple months ago, but man it sounds like driving over rumble strips since coming back from Moab, I will try greasing again, if it doesnt get better will order new joints

There is a Spicer replacment available for the front of the rear shaft, but I'm unsure of the rear one....

I have had to replace my rear driveline @ around 200K due to the splines in the slip yoke being worn, and causing vibration...FYI

good to know Alan, but mine isnt vibrating, only sounds like grinding when I let off the gas, which to me is more reason to keep my foot in it! LOL But all this is just since the taller tires and new rear springs and trip to Moab!

Like you need a reason, right?

Actually mine is doing that too, but only when just very light throttle is applied (still slowing down). I have been waiting to see if it gets worse and turns into a real problem...

Heh, mine is pretty loud when it does it, you would probably freak.

FWIW it has been doing it for at least a year...might be a little louder now though.

yupe mine too, I am experiencing VERY loud vibrations in the drive line after letting off the accelerator. I just assumed it was bad gear mesh in the Diff or the vast change in the angle of the axle shaft after lifting. It definitely got way worse when I put in the 2" spacers, so much so I am thinking of removing them

So Alan are you saying there is replacement for front, and the brand is Spicer? I cant find anyone that knows anything about this in Austin.

What is the diagnosis for this? unhook the front end of the driveshaft and check for free play?

The VX driveline has 3 lube points that need to be kept lubed.

Yeah, and for those of us with upgraded swaybar bushings we have 7 lube points, and if you replace the rear links it would be up to 13 I have been faithful to lubing and my u-joints feel A-ok, but the driveshaft is making all kinds of noise
