1970 Torque Specs For A Arms

[Eddie 70]

I am getting ready to set the engine in my car Friday or Saturday. I have waited until now to torque the bolts that hold the bushings in the a arms until after the engine is set in the frame. What should these bolts be torqued at? I need to know for the upper and lower control arms.

Thanks for any help you guys can give.

Eddie & Billy,

Here are all of them I have available for the a-arms:

Upper control arm pivot-to-frame bolts/nuts = 55 ft-lbs
Upper control arm shaft bolts = 60 ft-lbs
Lower control arm shaft-to-crossmember front bolt = 70 ft-lbs
Lower control arm shaft-to-crossmember rear bolt = 95 ft-lbs
Lower balljoint stud nut = 90 ft-lbs
Upper balljoint stud nut = 50 ft-lbs

If you need them for more parts, just give a yell.

Plus:

You guys are awesome!!

I was just going to post this question about a 1971 - now you are answering my questions before I even ask them! Can't ask for more than that!!!

If using rubber OE-replacement CA bushings, I'd do like JohnZ says ... torque at ride height ... because the rubber ones are bonded & no grease.

However, if using polyurethane CA bushings, I doubt if it's important to torque at ride height ... shouldn't matter w/poly ... as neither inner sleeve nor outer shell are bonded ... they're actually lubed w/silicone grease.

When I did mine w/poly, I cleaned those threads in shaft-ends real good & used a bit of medium strength loctite on clean bolts.

Regardless if rubber or poly, make sure the serrated inner sleeves bottom against both the shafts' step-ups & against the bell washers.
