positive camber problems

[Bill K.]

The guy who did the alignment thought it might be the spindle also. I don't expect CB Perf spindles to be wrong. What spindles to you have? Did you remove the control arms during the swap?

I had my control arms off and was wondering if somehow I didn't get the left side seated correctly. I'll check that before I remove them.

As far as your idea for modification, I don't know if that would work. Bending the arms does for sure, but it's tricky from what i've read.

The arms did not come off when i did the spindle upgrade , i don't think it is a fault with the spindle machining, i think it is the actual design ,mine are cb spindles also the spindle back plate is alot thicker so it may be that the top bj position has been moved outover to give room for the compensator nut giving the positive camber,without taking them off to compare i don't know for sure, iwas thinking of moving the arms in by turning down the urathane bushes in the end of the arms ,i don't have the equipment to bend the arms and am not sure what it will do to the geometry if they get slightly twisted etc when bent ,just out of interest how would you bend the arms?

Hi

Thing that determines where your arms sit in the beam is the dimple that the grub screw sits in, so turning down the bushes will have no affect.

...with a BIG press and skill/experience (I don't have either...)

If one side is excessive positive and the other is excessive negative, then it could be that the torsion springs are not centered and the center grub screw needs to be moved. That doesn't sound like your problem, but note worthy.

It could be tough relocating the end grub screws pockets in the torsion springs like you suggest -- material and configuration...

I'm going to call CB about my situation and see what they have to offer.

after i turned down the bushes i was going to turn the torsion leaves over 180 degree's re center them and shorten if needed and then redimple them to move the arms in , i have the machines to do this at work ,before i do all of this i am going to measure everything and see if i can come up with another solution , may just recenter the leaves as 0.25 degrees on both sides unloaded may be alright as they go more negative as they are loaded will update you with the outcome of my findings

Hi

Turning the leaves over could cause them to snap because of the different twit direction. Maybe you could bore the stock holes slighly deeper in the correct direction or maybe there is slight difference between your top & bottom leaves grub screw position?

FWIW, CB says they have never seen a bad spindle cause this issue and suggested to check the control arm for bend, the ball joint orientation within the control arm (notch lined up), or swap the eccentric. It doesn't take much...

Even though my beam is "new" it doesn't mean the arms are. They could be remanufactured and not be straight.

well it has been raining today so not much got done ,steve i had a look and the first thing i am going to do is to turn the leaves left to right on the top to see if this makes a difference, if that fails to make a difference then may have to look at a more radical solution , bill i would be interested in the outcome of measuring the old and new arms against each other ,to bend one of the arms would take quite an impact i would of thought, has your beam got urethane bushes or bearings in it , anyway one way or the other i am sure we will sort it
