Title: Need help with too much negative camber after lowering
Post by: ian75c10 on March 02, 2014, 06:50:56 pm

Hey guys so I need some quick tips on adjusting the camber on my 75 c10. So a few months back I cut a coil and a half off my front springs to give about a 3" drop. I have recently noticed that the camber is much too far negative. I can't afford a proper alignment just at the moment but I want to take my camber towards the positive a few degrees just for now so I don't keep killing my tires. I have never done this before but I believe adjusting the upper tie rods a turn or two each ( the same turns ) will achieve what I want as a temp fix. can someone help me out and tell me which way on each side and how to adjust these to give me a bit more camber in the positive direction? Thanks so much.

If you are having camber issues the only way to fix it is to adjust the upper control arm out to push the top of the tire back out...  Tie rods are going to give you Toe adjustments.

Ok good to know and thank you for the reply. Is there a chance you can give me a mini tutorial on what it takes to adjust the upper control arm? Ideally I can make the same exact minor adjustments to both sides for now just till I can get in for a proper alignment. I have to drive my truck a bit before I can get it aligned and it kills me to know I am wearing the insides of the tires that bad. Thanks so much for the help.

If you want to increase camber you need to add the same amount of shims on both ends of the control arm.

There are 2 bolts holding the upper control arm with shims behind it and the shaft, you have to add more shims to both bolts to push the top of the tire out.  Of course you are just guessing as cutting springs will require everything to be adjusted, dropped many like that in the past.

Very cool, I might attempt to do this today actually. So the truck needs to be jacked up? Any other pointers before I get in there and start unbolting stuff? Where can I get the shims? Thanks so much you guys.

Not sure if any of the local parts places sell those,  I have mine leftover from older trucks.
I didn't lift it up on stands, I just loosened the upper control arm and added shims, but this was a LONG time ago.  Now I just take it straight to the alignment shop..

Yes you jack it up under the frame, loosen the nuts, add the same amount to both sides so you do not disturb the caster setting. Use a piece of tape to keep the existing shims from falling out
