I need to replace the pinion seal and need some ideas on how to loosen the 1 7/8 nut, which is torqued to 450 lbs. I tried a 1/2 drive impact, 1:4 multiplier, and a cheater and I still could not budge it. Any ideas would be appreciated. Doug

 

Bigger impact or higher air pressure. I belive I used a 3/4" impact on my 99. Also we run 160 PSI. I had to use our bug air hammer (rivet gun that is twice the size of the 3/4 impact) to drive the pinion out. Our 4x rivet gun was not enough.

I did mine in the driveway and didnt have any trouble getting it off with a very large Snap-on ratchet set. I think it was a 3/4" drive. Worked like a champ.

 

Thought I answered this but now it's gone...

Use a long breaker or one with a cheater pipe and roll the truck forward with the breaker hitting the ground.

 

Thanks for all the input. Doug

 

Bill..........Good to hear you have that too. I thought I was nuts. Well, nutieerererererer than y'all think already.

BTDT, too. Several times over the years. Not as crazy as it sounds if it gets the job done properly.

 

Ingersoll-Rand 2135Ti @ 125 psi and a proper OTC impact socket. Like it wasnt even there.

Good tools for the win.

 

yep
