What do I torque the nuts for the pivot shaft on the upper control arms to? I tried looking in my Haynes manual, but they do not have the specs for those nuts.

This is an 86 Cutlass.

If I'm not correct you tighten the nuts till they bottom out on the shaft.

I have a '77 factory service manual and it has specs for the same thing, I would assume they would have them for a G body also.

Does anyone have a factory service manual to confirm what is correct?
 
it should be the same specs since the set up is the same.....are you talking about the nut at the end of the shaft that hold the bushings in place?

Yes I am.

The specs are kinda weird. It says 55 ft. lbs. for the rear nut and 90 ft. lbs. for the front nut.
 
I changed my bushing a few years ago and I'm sure I just tightened the nuts till they bottomed out on the shaft. If I'm not mistaken the shaft has a shoulder on it where the threads end on the shaft. Can you check to see if the shaft has what I remember it to be? For the last few years I'm running tubular uppers with a sold bushing so I forget some of the details of changing the bushings

Yes it has the shoulder where the threads end on the shaft. The thing is, it could be bottomed out on the shaft at 5 ft. lbs. or 150 ft. lbs. I would just feel more comfortable if I had the procedure/ torque specs from the service manual.
 
According to my 1985 GM Chassis Service Manual for Oldsmobile (Figure 42, page 4B-21):

The stabilizer bar is torqued to 35 ft/lbs
Driveshaft is torqued to 16 ft/lbs
Lower shock bolt to 64 ft/lbs
"Rear Upper Control Arm Nut at Body: 70 ft/lbs"
"Rear Upper Control arm Bolt at Axle: 79 ft/lbs"
"Rear upper Control Arm Nut at Axle: 72 ft lbs"
(tightening the bolt or nut is per your preference)

Rear Lower Control Arm Nut at Frame:70 ft/lbs
Rear Lower Control Arm Bolt at Axle: 79 ft/lbs.

Note: all tightening to be done with suspension at curb height.

I need it for the front.

Its for the nuts that go on each end of this, http://www.autozone.com/autozone/ca...ion+&+Steering&parentId=cat10006&questions=[]
