Default Control Arm Torque Values?

I am about to replace the front control arms bushings on my car, but before I start, can anyone provide the torque values for the nuts/bolts that retain the control arms once they are reinstalled?

Thanks,
Terry

Thanks whidbey...I searched also but my success with this particular search function varies wildly...Guess I need to refine my logic processes.

Those are the #s I have, if the last one is for the strut to wheel carrier

I just did the replacement this weekend. It took more time than expected but this was the first time I worked on suspension parts and I took my time. I wasted too much time on the first site to get the large sleeve out. For the second side, I cut deeper with the saw and followed the advice to make 2 cuts about 3/8" apart and than "open it down there like a sardine can". PIECE OF CAKE.

Back to the torque values. The manual is inconsistent. I found the referenced values above on the overview page but when you flip further to the suspension replacement it has the following values:

A-arm front to side member 77 lb/ft
A-arm rear to side member 63 lb/ft
Joint carrier to A-arm:
Caster eccentric 59 lb/ft
Mounting 103 lb/ft

Good luck and be PATIENT. Key is to make the hack saw cuts properly. Take your time for this. It will pay off big when you move to the punch.

Thanks for that...have my A-arms off now, Chris Walrod is changing the bushings and this will help in the reassembly.

Attached the following summary of removal, now updated for torque values, if anyone needs it.
