I've been loking at the different front axle build up's. I'm planning a knuckle out swap. I started looking at the different camber on the knuckle's. My use would be in a XJ it calls for 0 degree's, the swaped knuckles are from a 84 waggy and are also 0 deg. I looked at other jeeps that call for 11/2p.
I'm wondering if there is a 11/2n, and if so, would it help the on road stability of a lift and big tires.:rasta:

Camber probably won't have much effect, pos. caster and proper toe-in is where you get the straight line stability. Spring weight, good shocks and anti-roll set-ups will help in the slalom course.

Camber is the tilt of the tire as viewed from the front of the car. If the top of the tires lean toward the center of the car then you have negative camber. If the top of the tire tilts out away from the center of the car then you have positive camber.

Adjusting camber can have a dramatic effect on the cornering of your car. Most oval track racers run negative camber on the right side of the car and positive camber on the left.

Effects of Positive Camber
Slight positive camber results in a dynamic loading that allows the tire to run relatively flat against the road surface. Positive camber also directs the weight and shock load of the vehicle on the larger inner wheel bearing and inboard portion of the spindle rather than the outboard bearing. Positive camber in moderation results in longer bearing life, less likely sudden load failure, and as a side benefit, easier steering. Excessive positive camber wears the outside of the tire and can cause wear to suspension parts such as wheel bearings and spindles.
Effects of Negative Camber
Variations in negative camber can be used to improve the handling of a vehicle. A setting of 1/2° negative on both sides will improve cornering without affecting tire life greatly. This negative setting compensates for the slight positive camber change of the outside tire due to vehicle roll, thereby allowing a flatter tire contact patch during cornering. Excessive negative camber wears the inside of the tire and similar to positive camber, it can cause wear and stress on suspension parts.
Road Crown and Camber
A crowned road means that the outside/right hand side of the lane is lower than the left side of the lane. This improves the drainage of the road but adversely affects vehicle handling. Road crown must be compensated for in alignment settings because a vehicle driving on a crowned road leans to the right, causing some weight transfer to the right, and the camber changes slightly more positive. This combination creates a pull or drift to the right. Most alignment technicians adjust the vehicle with a slightly more positive camber, usually 1/4°, on the left to compensate for the road crown. This slightly more positive camber will not cause a noticeable pull when driving on a flat road. However, if camber is unequal from side to side with a difference greater than 1/2°, the vehicle will pull to the side with the most positive camber. If the specifications allow, 0° to ±.5° is usually best for tire life and vehicle handling.


All of which is racecar stuff - but I thouht you might like the theory.

Basically, what dirtrod said...for a solid axle 4x4, 0 camber is fine.

Since somebody has finally explained camber to me, felt too stupid to ask (effects), would somebody please explain to me why a waggy 44 would be a better axle for a springover than a scout due to a "camber issue"???????????

You've been mislead....the waggy is a better choice due to CASTER issue, not camber.

See, the scouts had little or none - making for very little return to center feel.

'course, if you're going to cut and turn the knuckles anyway.....

BV, thanks for your reply. You would'nt know the camber specs for a CJ D30 would you? :beer: or is that to JU of a question:rasta:

any pos camber will kill the outside edge of your tires
in cornering you need several deg neg to allow the outside tire to get full contact.

I don't know the CJ spec, but I'd bet money (canadian money, mind you) that it is 0. It's 0 for the waggy, YJ, and XJ with OK range of plus/minus half a degree
