I'm having a hell of a time getting the pinion nut off of my H-050 differential. I'm using a 1 5/8" socket with a 3/4" drive breaker bar and chocking the tires. So far it won't budge. Any tips? | | | | | Joined: Feb 2001 Posts: 1,096 'Bolter | | 'Bolter Joined: Feb 2001 Posts: 1,096 | I had this difficulty once , I got a piece of 1"x1/4" steel strap and drilled holes in it to match the yoke holes , bolted that on so the strap was tight against the ground , then put a pipe extension on the breaker bar.
With everything stiff, rather than trying to crank the truck over the chocks , it came loose. | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | You can also use a large pipe wrench with some padding on the pinion yoke if needed, again let it hit the ground to hold it.
Or usually an impact zips the nut off quite easily. (but you still need a plan to hold the yoke for retorquing by hand)

I'll give the pipe wrench a try first. I don't have much scrap steel laying around so if the wrench doesn't work, I'll have to rent a bigger impact wrench than what I have. I don't know what kind of foot-pounds it was torqued to in Detroit, but I'm willing to bet I won't be able to match it. I think I read 220 foot pounds, but I think I have a manual to double check that.
Thanks again!

That stops it from spinning.  | | | | | Joined: Mar 2009 Posts: 124 'Bolter | | 'Bolter Joined: Mar 2009 Posts: 124 | i took the whole carrier assembly down a local shop and i used their 3/4 drive impact wrench to pop it off. same for the reinstall. i used channel lock pliers to hold the yoke.
it took all of 15 seconds. | | | | | Joined: Nov 2008 Posts: 65 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2008 Posts: 65 | Thanks guys,
I can't believe this took me hours to do but here is what finally worked. I sprayed it down several times with penetrating oil and used the impact wrench with a pipe wrench on the yoke between doses of penetrating oil. While the impact wrench didn't work, I think it helped to get the penetrating oil to sink in. Finally, I got the pipe wrench on and the handle propped up on a jack stand so it was parallel to the axle. then I got the socket and breaker bar back on and put the handle on a 2-ton floor jack. I practically lifted the truck off the ground before it finally started to give. I finished it off with the impact wrench.
Wow! I had no idea what I was getting into, but I'm glad to have it off. Thank you all for the tips! | | |
