E body, these are 1/2" (I think) fine thread. FSM says 145lbs----that strikes me as really high.
What say the experts?

It's hard enough to get a wrench on them when doing a front end alignment, much less a torque wrench. Just make sure they are good and tight. I would also use anti-sieze on the bolt shafts and the threads. Sure makes getting them back out again at a later date easier.

You want em real tight but 145 ft lbs is a misprint. EDIT I'd suggest 85. I've heard reports 65 is too low (cam moved)

The 145 ft-lb is for the lower control arm pivot nut.

The upper control arm torque is 65 ft-lb.
Use a torque wrench.

I started doing alingments in the late 60s.Never torqued an upper arm.All you have to do is get them tight.Its almost like a torque setting for front wheel bearings.after you do a few you just get a feel for the setting.Most its hard enough to get a wrench on.Let alone in the rust belt where they dont want to turn.GMs we had a special SnapOn ratchet and sockets for the nuts.Rocky
