How often do you check your u joints?

I read on stus jeep site that he reccomends taking apart and checking/greasing the u joints as part of the regular maintenance, but I was wondering how often most people do this?

If it was necessary to take apart and grease, I would just replace them with grease able u-joints with zert fittings.

"The squeaky hinge gets the grease".

I don't touch them until they become a problem. Pulling them apart to clean and re-grease just isn't worth it for me. I do however keep spares on hand.

I check mine when/if I hear clunking.

I just replaced all my u-joints on my front axle last weekend. I had the front driveshaft out bc I got angry sparrows. Upon inspection, it turns out the centering ball had wallowed out its sleeve. I replaced the centering ball as well.

All the u joints still have the original grease in them and were in working order. However I replaced them with brand new greasable u-joints. I figure at 123,000 miles, it's not a bad idea.

I've been wondering the same as OP. Probably going to replace mine soon, seeing as 115k can't be good to them. Where did you get these greasable ones (part no.)?

depends on how big your tires are or how hard you wheel.

ive run stockers that ive checked yearly
now i run big tires on relatively small axles so i check them monthly(or anytime im wrenching under there really just cuz..)

i feel there is a basic maintenance if you wheel your jeep regularly and im always tinkering when it comes to these things like trackbar tighness, jam nuts coming loose off my currie ca's, retourqing things like lugs and such

Napa. IIRC they sell sealed and greasable models for both the cv u joints and the front axle side u joint.

I just replaced my front drive shaft front U joint when it started making noise, cheap POS only lasted 145,000 miles. I went with the grease-able kind from Orielly's .

At 145k miles, should still be under warranty.

Can't trust anything these days.

Thanks to this thread I dropped my skids and greased my front driveshaft and all the other Zerks while I was at it! Thanks for giving me a thing to compulsively check!

www.drivetrainamerica.com/ Do yourself a favor and buy some spicer stuff unless you really like changing them all the time. There is a reason the stock ones last 145,000 miles.

Damn Jeep, should have never chose Spicer, 145K is laughable!!! Chinese made parts-house brand should have been there from the get go.
