Torque spec on axle nuts and bolt 2002 Peterbilt

gonna do brakes this weekend and my axle nuts are a little wet with oil. So I’m gonna pull it, clean the base up and permatex it. Need to know torque specs for putting back together. Than you. 02 pete

 

Should be 100 ft lbs.
Looks like you have 1 bolt not nut??

 

7/16” 50 ft lbs
1/2” 75 ft lbs

Use grey Permatex, not a gasket. Gaskets will make you pull your ####ing hair out and light it on fire.

 

Those are 5/8-18 fine thread axle flange studs. The proper torque value is actually 180ft lbs. With no axle tapers these flanges will loosen and move on you so make sure they are tight. The above spec is lubed threads. Probably as high as 240ft lbs if dry.

 

Ok . Thank you. Was going to use the blue permatex. Grey better?

 

Get a new gasket. Clean and dry.

 

Ok will do thanks.
What is the gasket called for when I go to truck parts place in the morning. Axle gasket? Any specific type or are they all the same

 

Mr common 8 hole axle flange gasket for class 8 axle shafts. If in doubt just press a cardboard template on the bolt circle for a sample to take with you.

 

a good few ugga dugga's with a strong 1/2" impact. should be 150-180ft lb tq spec for 5/8 grade 8 bolts.

i normally use "the right stuff" gasket maker.

 

Cam,

If you look close at the hub, the boss with the bolt in it likely goes all the way through to the hub cavity between the bearings. This would allow you to drain the hub oil by pulling the bolt out and hole in the down position. Rotate the hole back to the top and add a qt to fill it up again or to fill the hub cavity after installing a new seal. Also keeps from making a mess when doing a wheel seal to drain it first. I definitely apply sealant or blue threadlocker to the bolt threads to keep it sealed up.
