I'm currently installing the upper control arms in the rear, I have no idea what the torque spec is for any of the five bolts, can't find them anywhere. Any info greatly appreciated

I sure hope those 5 bolts an 4 nuts are stout. Here are the torque specs as listed in the service manual. Upper control arm bolt sub frame reads 59 lb ft on first pass, then final pass of 120 degrees. Upper control arm to knuckle reads 44 lb ft on first pass, then final pass of 90 degrees. Install the upper arm pivot bushing an bracket to sub frame (observing the correct directional install mark on the bracket). Then make first pass of 29 lb ft, then add 90 degrees on the final pass. Secure the upper control bushing assy to the upper control arm bolt to 125 lb ft. Hope this makes sense.
