control arm torque specs

[james750]

Today I am installing my currie track bar and control arms. I read in chilton that the control arms only need to be tightened "finger tight", is this right? and if so, does that torque also apply to the currie setup?

 

Thanks

I think it is finger tight until you drop it down and get weight on it, then you need to tighten them. I will check my fsm and see if i can find the torque

[james750]

ok, I just found that on the web, it also says that the torque should be 55 for the uppers and 133 for the lowers, thanks maddzz1!

 

 

Also, when I raise the vehicle, should I support it by frame with the jackstands and take the load off the axle, or should I support it by the axle (still having load on the springs) with the jackstands.

 

I know, noob question... :dunce:

The fsm says:

 

upper at axle: 55ft/lbs and 66ft/lbs at the frame

lower at axle: 133ft/lbs it doesnt list seperate so must be the same at frame

[maddzz1]

I would try to support it at the frame with jack stands and put a jack under the fron diff to let the axle hang if you need it.

Also, the fsm says tighten and then lower the truck :dunno:

[james750]

thats interesting, b/c ive found 2 places online now that say to tighten it after lowering the truck or ride comfort could be adversely affected. :hmm:

Definitely tighten at ride height.

 

Same goes for leaf springs.

 

Anything that moves with the suspension should get final tightening or torque at ride height. (Tires on the ground sitting normally.)

I don't know why the FSM says tighten to spec then lower vehicle. If you did it that way I would think all the bushings would bind up.
