Can someone post where you've purchased your replacement joints w/ grease fittings. I need to do this soon, getting some vibration through the floorboards at moderate speeds and I'm thinking this is the culprit. Thanks fellas.

 

So what are you waiting for, want the u-joints to fail and take out your tranny.
Go out today to Auto zone and buy the u-joints and centering ball kit if they have one, otherwise while you are waiting for everyone to give you feed back you could loose the drive shaft and tranny, apx. $7000 in repairs.

 

I bought mine at Napa Auto Parts for my 2000 Discovery. They are Precision #344 for $27.00 ea.. I changed all four at the same time. Also look at your rubber Rotoflex coupler on the rear drive shaft. If the roto-flex has cracks in the rubber you will notice severe vibration while accelerating and decellerating from the shaft being tourqed off center. Rovers North sells the roto-flex P/n RND196 for $89.95.
