Whats wrong with this u joint?

[OLDCHEV4X4]

I was changing the rear diff oil in the 1008, and I noticed this.....
(In the rear drive shaft).

looks like you're missing a zerg fitting

Yep. no grease fitting= no grease in the joint. Or atleast doesnt look like it has had any put in it in awhile.

The shiny lugs on u joint indicate some slop in the connection. When you replace the u joint, you should get new hardware (bolts & straps) These are available, just say you want u joint straps for a 84- 86 k-30. Some oem u joints had no grease fittings. If the truck is very high mileage, and has been run with bad u joints, one can add some strips of thin machinist shim stock to take up slack in axel side of yoke. See you are missing zerk , but above is all true.

Dependable is getting close... but no cigar yet!

its the wrong u-joint for a 1008, shouldn't have inside snap rings on 2 of the caps

WE HAVE A WINNER!!!!

ODdave wins the superman super spy ring!

Its a front axle end u joint (1.125 caps).... in the rear driveshat position (1.1875 caps)

I got it this way from GL. The rear uses external G shaped clips and the front axle ends use the internal C shaped clips. The army put both kinds of clips in and called it good.

is this the same as for the blazer? if so can someone explain this to me. I fear i may have done something wrong on my truck.

 

[ODdave]

No, blazers use all four clips

 

[Mudstone]

ok whew... thank you. i was nervous for a sec

Looks to me like its missing the momentum modulation unit and the attached widget.

What do you use? A welder? Machined for external retaining rings?

All the same size caps.
Nothing was tight, i cant believe the thing stayed in there.
