Control arm caps
 

Can anyone tell me what size the upper and lower control arm caps are? Looks like I'm gonna have to either borrow or buy the tools to fit them as the biggest I have is 1 1/4" - thanks for the help!

I used a flat jaw pipe wrench. Worked for me.

I've used either a pipe wrench or @ my work we have some huge cresent wrenchs.

I've got a big pipe wrench, but I didn't want to take a chance on screwing up the caps - that might be the way to go.

Just start them like a normal bolt & when you can't tighten them by hand, start using the pipe wrench & work slowly.

yeah take it slow...i think the torque spec for my 70 c/20 caps were 250 ft/lbs...

Thanks for the replies guys, but I'm trying to disassemble - I have a little bit before I am read to assemble

The uppers are 1 3/8 inch and the lowers are 1 5/8 inch.

I know, I had to buy both wrenches last week to do mine :) .

That is for a 71 C10, It is prolly the same for c10/c20 but i'm not sure...

Sweet! Thanks Cheyenne - did you replace the upper and lower control arm bushings? Any advice you can throw my way that would make the first time easier?

MAKE SURE that the threads are clean of paint etc. in the a-arms before you try to screw in the caps. it makes it VERY hard if you dont. :banghead: :banghead:

Also, make sure the upper shaft is perfecetly centered in the a-arm. Keep measuring from the side of the a-arm to a hole, then the same on ther other side. This is not crucial while you are doing it, because you can always spin the shaft to move it left or right, after it is all together. It's just gotta be in the middle when you go to put it on....

And ummmmmmmmm, just have patience, some of mine went right in, some of them went in like a %@&#. I think that was because some of my threads still had some POR15 in them though....

Hopefully this ain't too confusing..... anymore Q's just ask....
