My U Joints are shot!!!

Very good Tom

Thanks for the correction.

The Universal Joint is the combination of the Yokes, The Cross, and the parts that keep 'em together.

I greased my U joints this evening, but I could get much to even penetrate the zerk... weird.

Awesome Image of the complete U-Joint

Back when I used to run parts (when I was 17, so 10 years ago) I used to go here:

For all of our driveline components.

If you removed your U-Joints, and brought them in I bet they could match them up and possibly upgrade you to better units.

Just a thought for those in need.

sorry, no video tonight.. got called into work.. should have it up over the weekend

my joints took a little muscle to force the grease through... if you are having grease come back out of the zerk fitting, it either means your fitting is jammed up with a small pebble or your grease gun tip is the wrong size

"I greased my U joints this evening, but I could get much to even penetrate the zerk... weird."

Two thoughts:

1) they don't hold much grease - just a small hole down the length of each leg of the cross to allow the grease to get out to the bearing cups (also happens to be the outer race). The cups aren't that big & they are pretty full considering that they cover the needle bearings and the ends of the cross (inner race). Basically the only room for grease is the area around the needle bearings.

2) without regular service (grease) the bearings could have gotten hot enough to 'cook' the grease & make it harden. You can't force new in if you can't push the old out.

I had an old Dodge & the U Joints didn't have Zirk's. When I finally went to replace, guess what ... no grease in the cups & no needle bearings either - just rust colored dust.

If you take your front or rear driveshaft off for any reason, put a mark or scratch on both flanges to line them back up to the same position when they go back.

"If you take your front or rear driveshaft off for any reason, put a mark or scratch on both flanges to line them back up to the same position when they go back."

'Zackly - that's the phase I mentioned earlier - the front & rear U-joints need to be oriented properly with each other.
