Never mind - I had a brain cramp.  Found the entire torque spec table in my shop manual.  Sorry
M

The 55 Ford manual says 55-75 for the lower/60-75 for the upper.

Great info - once again.  I too am in the process of rebuilding the front end on my '55 Glasstop.  I will now wait to torque everything until the car is on the ground and full weight.  How much should I torque the a-arms to?  I found one video for a C-10 and they were using 160ft/lbs.  Otherwise, I haven't found the specs.  Thanks

Nice write up Dan. I finished my front end yesterday but I'm fortunate enough to have a press which makes it a lot easier. Now to check camber and caster and hopefully I'll be within specs

I can echo Ted's recommendation on waiting to give a final torque until the full weight of the front end of the car is resting evenly on the suspension.  When I completely disassembled the front end of my 55 Ford Club Sedan, did some work on the crossmember, had the engine and trans out, etc, I agonizingly waited until everything, including the front bumper, was reinstalled before torquing the nuts on both the lower and upper control arms. I have not used any lubricant on the bushings, but I did use some anti-seize on the threads of the shafts and the bolts when I re-assembled everything. No problems so far. There is quite a bit on my website if you are bored.

Thanks. I get it now. I did not know that the rubber internals of the bushings flexed with the up and down motions of the control arms. With that knowledge in mind , the upper shafts and lower bolts have a chance of being reusable.  

I worked the lube rack at Sears in the 60’s. We had a spray in a pump bottle of “rubber” lube. It would silence squeaking bushings for a while and worked best in dry weather. I searched for a product to replace it over the years and found Ru-Glyde 2 years ago. It’s a product that was for mounting tires and work pretty well. I spray the bushings with every lubrication on the zerk fittings. The more often I use it the quieter the front end has gotten. I watch where in spray it and wipe off the excess.

That’s a YES on the rubber part of the bushing taking the blunt of the control arm movement.  To ensure that the rubber is not in a strain or bind when the car is in a relaxed (not moving) position, I will tighten those end nuts only after I have lowered the car so the normal weight of the car is on the wheels.  This will have the movement of the rubber in an equal strain in both the up and down positions and not at a normal or relaxed position.

If tightened while the car is still up (wheels all the way down), then the rubber is in a non-relaxed position when it’s in a normal stance and in an even more unrelaxed strain when the front-end nose dives some.  I feel that some of the squeaky bushings are a result of the rubber in the bushings being stretched beyond its limits and having some tear within them.  Some of that can be traced back to either aggressive driving, bad shock absorbers, and/or just installed where they are in a non-relaxed state when sitting at a normal stance. I trust that made sense.

Other comments always welcome.

I had thought that there is some movement on the metal surfaces where the inner bushings contact the upper shafts and lower control arm bolts ,thus requiring some lubrication. When a car hits a bump, does the rubber in the bushings stretch to accomodate the up and down movement ?

I typically only use a shot of WD40 on the metal to metal press fit parts.  It’s the rubber bushings themselves that tend to squeak on some vehicles over the long haul.  I rebuilt the front end of my ’55 back in ’89 and after 200K miles, those bushings are still quiet.
