So I need new U joints and dont know if I should go with greasable or non greasable joints. What do you guys suggest?
Thanks for your input.

 

Just my experience here...

Grease-able don't wear out as fast (if kept greased) but are not as strong, non grease are stronger but wear out faster...

Now that just might be me and the wheeling I do (LOTS of moisture)...

 

A well greased non-greasable u joint will last ten years if properly installed.

 

I have heard that non grease able are stronger but not sure what to go with. The ones Im replacing I assume are the stock ones since Ive never changed them in the six years Ive owned my XJ. I plan on eventually upgrading my diff(when funds permit) but for know I need to keep it running with the least amount of money. Thanks for the input, I appreciated.

 

If you are planning a change soon I would just go with the non grease-able they are stronger, just make sure you get them greased up good before installing. They should last long enough if you plan on the change fairly soon, and are stronger.

 

Excuse my lack of knowledge, how exactly is properly installed? I thought the installation was pretty straight forward.

 

well dont destroy the needle bearings or the caps when you install them, thats pretty much it lol, and non-greasable ones are stronger, the factory ones are non-greasable and i just had to change my rear driveshaft u joints for the first time

 

The pressure you apply to the caps is critical. The play you leave should be 0 but at the same time the joint must rotate freely. Don't use a hammer unless really necessary and be careful to place the shaft perpendicularly to the press piston (if you use a press) or the caps will seize in the yoke.

 

or you could use the old vise and BFH trick...

And what about these guys? any opinion on these?


or is everyone stickin' with non-greasers are stronger...

 

those are some decent u joints. I gues the yokes are the weak point with such u joints.

 

thats what I figured, but I'm not worried about. everytime I've seen a yolk toast it was because the u-joint failed.
