I have swage tube uppers and it always seem to take 4 or five adjustments till I get what I need. I always set camber first. So my questions are If I need more caster, how do I adjust with out changing my camber? I use turn plates, but should the wheel be locked by the brake or let it rotate when turning the opisite direction on caster?
This site rocks thanks for the help guys!

let the tires rotate. Also I like to bounce the front end and roll the car back a few feet then forward a few feet and recheck, that will settle the chassis. I always set it in this order: Caster, Camber, Toe. If you are setting the front alignment and it keeps changing after you roll it or bounce it then you either have a bind or a bent part or both LOL! Also you asked how to set caster without affect Camber..... you can't One affects the other. The only part of front-end alignment that doesn't affect something else is the toe. Toe doesn't affect caster or camber BUT caster or camber can affect the toe! Hope that helps

I know this one isn't bent yet its brand new. But I will try caster,camber, and then toe, (which is the exact oppisite order I have been setting them up). That is also oppisite the order the insuctions that longacer gauge. Thanks for the suggestion I will give it a try. http://www.longacreracing.com/instructions/inst.asp?INSTID=5

I checked that link and didn't see any order instructions??? I used to be an automotive tech for Chrysler and I also went to Nashville Auto-Diesel College and various other schools for Chrysler and that is the order they always taught us to use. Maybe that will fix your problem, if not re-post and maybe we can find something else LOL!!

1. Caster
2. Camber
3. Toe

Don't lock the wheel. Always "settle" the car after you let it off the jack after making a change.

You usually end up having to adjust it a couple times to get what you need. If your camber is close just lengthen one rod and shorten the other to change the caster. If your caster is close lengthen/shorten both rods to get your camber right. Don't forget to reset the toe after changing caster. If its a big caster change you may even have to reset your bump. If your turn plates have slides then the car should settle pretty good but its not a bad idea to bounce/roll it after each change.

FWIW I don't adjust camber/caster in any particular order, I check both then make an adjustment to get them both right. I do always set toe last though.

I would take a caster and camber reading and make adjustments that will move both angles in the direction I want at the same time.
If you move the control arm evenly in or out you move camber only. If you tip it to the front or rear you move caster also.
Always watch your camber as you make adjustments. Always make another caster sweep after each adjustment.

To get more positive caster without changing camber. Note your camber and move the front out. Camber will go positive. Do 1/4 or 1/2 degree at a time. Move the rear of the control arm in until your camber is back to where you started. It should give you 1/2 to 1 degree more positive caster.

a good thing to remember is a 1/2 deg of + camber is worth 1 deg of + caster change may not be exactly that but is usually pretty close and u can fine tune frome there. opposit if u - camber. always set camber then check caster before making any other adjustments.

I'm assuming "reset your bump" refers to bump steer. How do you reset it? I don't have a bump-steer gauge...is there another way to check it? Are there any articles on learning more about it?

Thanks,
