Hey, im having a problem getting the new rear upper control arm ball joint all the way into the socket at the top of the differential. (2006 KJ) Theres just maybe 2mm left but i cant pass the bolt through. Ive tried putting a chisel into the gap, jumping in the trunk, angeling the differential with a jack, using a ratchet strap while driving over a speed bump, i sprayed it with oil... Nothing works. Does anyone have any tips on this? Any similar experiences? Thanks a lot
Rear upper control arm wont go in all the way

I think I used a chisel in the gap ,a clamp on the arm and axle shaft and rotate the pumpkin for or aft and it dropped right in.

Remove bracket from axle, insert ball joint, reattach bracket to axle.
I ended up hammering the bolt in, it went in relatively easily and the thread was only lightly damaged so i could screw the nut on normally, maybe the new ball joint just wasnt so precisely designed either way it should hold because the bolt is in the groove
Btw for anyone reading in the future i did the replacement without lifting the car and without taking off the tires, its not necessary

If I understand what you are saying correctly, that is NOT the case. When you disconnect the upper ball joint at the differential you no longer have any support to keep the differential from rotating (probably) upward. The shocks and driveshaft will somewhat limit this movement but it could still happen if you the lose balance of the lower control arm suspension assembly.
May not move far but if your hand is in the area of the ball joint it could definitely pinch or crush a finger or hand.
Obviously you got lucky and nothing bad happened, but this statement should be deleted to protect others who dont know better.
I did the same, a jack under the rear end and a slight rotation and it slipped right in.
Kind of just like … oops wife just walked in
