While I had a half shaft out for wheel bearing replacement, (that's another thread) I thought I should clean and regrease my u-joints. After removing the joints and cleaning them, I laid out all the parts.
I didn't know these are special u-joints that have grooves to hold the needle bearings in place
I smeared a little grease around the inside of the cup to help hold the needles while I assemble them
I see one of them broke off, but it's ok as I have the broken off piece.
im not sure how much wear happens to the tolerances or not. about the onlypossible downside may be if they are worn out and loose im not sure rebuilding would last.
for a daily driver id say this is perfectly acceptable in my book! im a big fan of keeping sunk costs as low as possible for the street. if its a racecar or piece of equipment that generates revenue then i pm like crazy.
were they tight at notchy prior to your cleaning?
after cleaning are they floppy and smooth or tight and smooth?
👍👍👍 i think your post will help some new young owners who are refurbing thier new to them c4’s

..... Please tell me this was a hoax ! ..... Those grooves are from wear , they were NOT machined into the caps and trunnions on purpose ... there was a broken needle bearing for crise sakes ! ... spring for some new ones .....
..... I see them installed right where they belong ! .....
My 88 has a squeaky and popping RR outer u joint, (total carnage inside) so I ordered all 4 for the half shafts and 2 for the driveshaft.
For the labor (my labor) and price of the new ones, I wouldn't bother to try to re grease u joints.
They should be here Tuesday and I'll get er done next week.

All done! Just like new.
Time for installation
Lol. A 2nd look is needed.!
Many.. did not read & look at the complete humorous posting.
I have studded rotors and pressure plate to aide with the Recycled U-joints.
Glad its a joke.thing is so many are that cheap they will do just that.
Yrs back a member was being smart to someone giving advice on breaks.
So the "helping" member said he could fill the M/C with pancake syrup...it would still stop.
Week later you see the guy posting a " xxxx member tried to kill me!" thread
he actually did it.cheapazz.
The real installation
pull one cap off and carefully slip the bare trunnion in the yoke, and set the opposite side in its yoke. Don't let the trunnion touch anything so as to not pick up dirt. Carefully put the cap back on and push as far as it will go.
Find a piece of pipe or a socket that is just smaller than the cap. You don't want to push on the middle as this can deform or break the cap. Open the vise up and with the socket in place press it the rest of the way in. Be careful not to overdo it.
Once the cap in fully pressed in, install the other retainer. Your new ujoint may feel tight, and it likely is. Take a hammer and tap around the yoke to seat the caps properly. On this one I had to tap the inside of the yoke outward to set them.
