pinion loose

[westtexask5]

for some reason i can't get the pinion nut tight enough. i replaced the pinion seal on the front diff and when i tried to tighten the pinion nut the pinion itself is still loose. even with a 2 foot breakover bar i cant get it tight...any suggestions?

Do you mean that the pinoin has slop in it? If so it sounds like you may have cross threaded the nut or damaged the threads while removing the seal.

i bet your just a wuss! ha ha
NO we got it tight it was just the thickest crush sleeve id ever seen and it to ALOT to get it to the crushing point.

Just swapped out my 3.42's with 4.10's. Did you replace the crush sleeve?

Those crush sleeves require a lot of torque to squeeze. I had a 2 foot breaker bar and 4 foot extension pipe. You should have no end play, plus it should take 20 to 30 inch pounds (new bearings) to rotate pinion (10-15 inch pounds for used bearings). That is pinion alone with no ring gear installed.
