The Stovebolt Site Forums The Shop Area Driveline Carrier Assembly to Axle Housing nut torque specs

I'm sealing up my rear-end. In the Shop Manual, I think I found the Housing Cover Nut Torque Specs @ 20-25 ft/lbs. For the life of me I could not find the specs for the torque on the nuts that secure the Carrier Assembly to Axle housing. My truck is a 1959 1/2 ton, 3.90 gear ratio

I believe this is what your looking for Link

This for 1954 truck

The "Torque Spec Rear Axle" is under: Differential Side Bearing Caps

Depending what tonnage of truck you have.

Thanks

Thanks for the reply. Please excuse my ignorance on vintage Chevy terminology. I'm an old Volkswagen guy, this is my first vintage Chevy. I think I am using the wrong terminology. The middle of the axle housing has two portions secured with ten nuts, the back cover and then the front portion that attaches to the drive shaft. I need the torque specs for the nuts that secure the driveshaft side to the axle housing.

What year is your truck.

Is it 1959 Apache

I think You want torque spec on carrier assembly housing to axle housing nuts.
or third member to axle housing

In the shop manual, step 2 of installation says; "Assemble differential carrier assembly to axle housing, install nuts and tighten securely.". I did not see anything about torque specs. Hope this helps.

Hi, thanks for the link. So what grade do you think the studs coming out of the axle housing are: SAE 5, 7, 8?

Well, I would play it safe match-up nut with a socket to find nut size and use the Comm. Low-Carb column.
Heck there is 10 ten bolts & nuts that thing not going any where. 50 elephants won't pull it off.

Besides the housing would break before the bolts snapped off.
You sure do not want to over tighten the nuts and snap off a bolt or strip the threads.

Then you would have a problem.

I'm more worried about the differential carrier assembly and housing cover leaking gear oil than them falling off. I ended up torquing all the nuts to 33 ft/lbs. how's that?

If you cleaned the mating surfaces and used new gaskets, you should not have any oil leaking issues.

If you want to get a 2nd opinion on how to do this correctly you can call Patrick's Antique Cars & trucks at 520-863-1117

Tell'em you found out about them from Stovebolt.com

Just talked to Patrick. He said 33 ft/lbs is plenty and not to go much over that. Thanks for the tip
