Need trailing arm spindle nut torque spec.
I need to find/know the trailing arm, spindle nut, torque spec?
And any other specs you need to know to do the trailing arm rebuild job?
Are the bearing set up toque specs the same as the spindle nut toque specs, when a set up tool is used?
I did a quick search on this topic and nothing came up. Does anyone know of any really good detailed sights that tell you how to assemble the trailing arms with tips and hints about making improvements. I have visited too many sites that give a breif overview of how to tear apart the trailing arms, and vaguely show/describe how to rebuild them, but give no specifics, other than "send them out to the pro's." Thats ok for the faint of heart, but I'm a ground pounding, bottom feeding, do it yourself, who would rather fix it myself and know what was done and risk screwing it up myself rather than be disappointed with someone else's work or over pay for their service. Seems like finding the details of this job are like asking for the secret to an ancient chinese magic trick or something.
Hope someone can steer me in the right direction.
Be cool!

Re: Need trailing arm spindle nut torque spec. (73 Teach's Pet)
Hey, Teach!
Looking at the crib sheet that came with my rebuilt t/a's from Van Steel (yes, I chickened out of the DIY job on these!) the spindle nut torque is 100 lbs/ft plus whatever is required to line up the cotter pin.
It also says: "WARNING! If the assembly was not properly set up, tightening the spindle nut will load the bearings and cause imminent bearing failure."
Sorry, I'm not aware of a good reference for a DIY on this job, because one quick look at it, and knowing I could get A-1 results from Van Steel for reasonable prices, and I quit looking for books. Nevertheless, I suspect the actual GM shop manual has what you need. You oughta have that book regardless. Good luck! :seeya

I believe that you torque to 100lbs then back off to line up cotter pin in order to avoid over loading the bearing. I hope I'm right 'cause that's how I did mine.

Hey, I'm not saying you're right or wrong, 'cause I don't know. But the Van Steel sheet clearly says "100, PLUS" what's needed to line up the pin. It's little stuff like this that drove me to pass on the DIY for this job! :eek:

I rebuilt my TAs last fall. It's not rocket science. You will need a dial guage and some sort of bearing preload tool to set up the shim for the bearings.
