Re-Installing new Control arms & bushings...lil' Help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ChevyDude · 10-25-2004, 12:10 PM

Ok my wheels of progress move slow....but I am ready to put my new upper and lower Control arms together and wanted to see if anyone has any tips how to keep the "A" arms centered as you tighten the caps through the "A" arms and onto the actual control arm. There is inside and outside threads to all go together and be centered. Is it best to install the upper Control to the frame and then screw on the caps through the "A" arm and onto the Control arm??? How about the larger lower Control arm...How do you keep it from spinning as you tighten the caps??? Is that what that hole indention is for...some sort of tool???? Any help or tips will be appreciated! Ball Joint install upper/lower was a snap....providing you have a press for the lower ball joint.

Thanks!

I'm trying to think back to my bushing replacement...?
If I remember correctly the end caps are tightened by alternately turning one cap and then the other the same amount, this ensures it is horizontally centered. It can be difficult and may require someone to hold the bushing at first. I think the indentation should line up with a flange or something to prevent the bushing from spinning, damned if I can remember, It's not for a special tool though.
I lent out my manual so I can't even refresh my memory!
I do remember the installation was a helluva job and I had to re-do at least one side because I had something reversed, and it was hard as hell wrenching the caps back on the bushing. I put my bushings in when the A-arms were off the vehicle, I had to wedge them under something in order to exert enough torque!

On the top Control arm you can bolt it to the frame, slide the bushings on and put the "A" arm around it. Then screw in the caps through the "A" arm and onto the Control arm. This way the Control arm won't spin because it's bolted to the frame. Just wondering how you keep it centered. The lower is another story as U bolts hold it on to the frame....so.....

Come on guys...Someone has done this job and inquiring minds want to know!

Alex,
I believe the only trick to keeping the bushing centred is to tighten both ends alernating from one side to the other. For instance half a turn on the left half a turn on the right and so on until they're both cranked down. Either the manual or the parts installation instructions indicated this was the proper way to ensure centred installation.
