so today was a crappy day, went to change my rear driveshaft u joint and found out that the yoke on the rear diff is shot too, the moving of the u-joint shaved down some of the metal in the yoke, so does anybody know where i can get a new yoke?

 

junk yard

 

yeah i figured that would probably be my best bet

 

Getting the pinion nut loose might require an impact gun.

This may not be easy to do at the junkyard.

 

yeah that was my other thought, ive changed a yoke before on a 71 cutlass and i had to use an impact gun for that, i mean i can get an oem yoke for like 25 bucks, which is 10 bucks more than one from a junkyard, and its new so i dont have to worry about the same problem i had with this one

typical jeep thing though, something simple turns into a whole ordeal haha, gotta love it

 

wait a second, do you think the u-joint that autozone gave me is the wrong one? i know i need a 1310 u-joint for it, but how can i tell if the one i got is the right one, i now the yoke is a little over 3 3/8 wide from where the u-joint sits in it, my u-joint is about just 3 3/8, i figured that was from it wearing out, do you think i just have the wrong u-joint?

the other reason why i think its hard to believe that the yoke is bad is cause the u-joint wasnt bad for long, maybe a week if that, and i didnt do anywheeling or highway driving so nothing to strenuos for it

 

compare it to the front its the same size as rear

 

You also run the risk of damaging the crush sleeve on the pinion gear when changing the yoke. Verify that you do have the correct u-joint before pulling the yoke off.

 

yeah its the right u-joint, so i guess i gotta get a new yoke, is there anyway to change the yoke without crushing the sleeve? besides just being careful

 

it hard to screw up a crush sleve by hand take a 18inch pipe wrenc to hold the yoke and a pc of pipe to slip over the 1/2 inch ratchet with the socket that fits the nut on you yoke and a hammer to junk yard you will be good just dont over tighten the nut when you put it back on there not as tight as every body thinks

 

The hard part about pulling one off at the jy with hand tools is keeping the wheels from turnning. Every do it yourself jy I have been to puts the vehicles up off of the ground and the force needed to turn that pinion nut is going to spin the axles.

 

put rims under the pipe wrench that holding the yoke

 

well i ordered a new yoke, its only about 10 bucks more expensive than one from our pick a part, ive got a breaker bar i can use on it, and is it fine if i put the e-brake on to hold the yoke still? thats how i got the driveshaft off

 

well good news! i went under the jeep to mess around with the driveshaft, well i put it on it moved, so this thought popped into my head "hey maybe these caps are too big?" so i put the old ones on it, which were in good shape still and..... no movement at all!! the new caps were too big and werent holding the u-joint like they were supposed to be, so problem solved, now i just gotta ship back the new yoke and get my 40 bucks back
