C2 poly a-arm bushings

[Howard M.]

Just checked my records and discovered that polyurethane bushings were installed in both the upper and lower front a-arms in 1993 in my '67.
Can someone tell me what the bolt torque should be? It's probably time to check it.
Thanks

Howard,

The instructions that came with mine say "torque to factory specs".

We would encourage all mid-year owners to spend the $20 on an Assy. Instruction Manual, which has all kinds of useful information --like the torque values for your A-arm bushings. Even gives you the helpful hint to have the wheels on the ground when torquing.

If you've never done it, it's not a bad idea to retorque ALL your suspension fasteners.

Re: C2 poly a-arm bushings

Lower bushing bolts are 45-55 ft-lbs., uppers are 30-35 ft-lbs. with OEM rubber bushings; have no idea what they are with poly bushings - do they have inner sleeves?

should they have anti sieze?

i posted earlier this week mine were all but backed out and one gone. i pulled one just now to go to the hard ware store for a temporary one till i can order a replacment and noticed a generous amont of anti seize. this does not make sence to me and may be why they backed out. any ideas?

First, are the bushings you had installed polyurethane type? Second, what has "pulled out"-----the outer shell of the bushing from the control arm OR the elastomer component from the outer shell?

Re: should they have anti sieze?

they are poly A frame bushings and it is the bolts that backed out, one all the way.

Re: C2 poly a-arm bushings

Thanks to all:
Yes, the bushings have inner sleeves. Therefore I would suspect that the bushing bolt torque would be the same for poly as for rubber. I wonder if the use of threadlocker might be in order for this application. anyway,
the car goes on the lift tomorrow to check all the suspension bolts!

The bolts are threaded into the control arm shafts. I do not understand how the bushings, whether original or polyurethane, would affect the retention of the bolts, assuming that they were installed with the suspension loaded and correct torque to begin with. I would clean off any anti-seize compound from the threads (both bolt and shaft threads) and re-install the bolts using medium strength thread locking compound.

Re: should they have anti sieze?

How it does is not of concern, but fact is, they will fall out like a bad set of teeth, so use thread lock, and poly-grip if necessary, to keep them in.
