[358429]

Does anyone have a resource that lists propper torque specs for things like:

 

-lug nuts

-front suspension components

-rear suspension components

-u-bolts

 

Havent had much luck finding anything, so thanks in advance.

[MS3DALE]

I can tell you right off the top of my head that lug nuts are 140 ft.lb.

I'd have to look the other stuff up...Is it 2 or 4wd?

[MS3DALE]

OK,I went with 4wd,See if this helps you.....

Thanks a million. Where did you find all that stuff?

Yup, its a 4x4. Do they make any 900s with the Z-71 package in 2wd?

Thanks again.

You can guess what is on my to-do-soon list, huh. Sorry, I focused on looking for "shackle" and did not see the "hanger" spec...

[Matt_]

Wow, the body mounting bolts are only 44 ft-lb? I guess i'm good with the 85 I've been going to (it probably changes due to the longer bolts of a body lift... BDS claims 90 and PA claims 70 in their instructions)

[ffthornton]

can some one tell me the torque specs for steering linkage on a 2008 gmc sierra 4x4 z71 1500? Thanks. I looking for the part that attaches to the knuckle.
