Other than looking at camber on the alignment rack which could indicate one of several problems... How to I specifically measure to properly diagnose a bent C on the front axle?

Based on the gusset designs, it looks like they're trying to protect against the C opening up when it bends. If that's the case, then it seems like we should be able to measure that with a Vernier Caliper.

Any ideas here?

 

The stock camber is a little bit negative, This is normal.

CAMBER − 0.25° (fixed angle) ± 0.37°
MAX LT/RT DIFFERENCE ± 0.5°

If you want the truth, go to an alignment specialist

Also, check your ball joints (each 6 months)

 

Good advice from JKU RUBICON, check your ball joints. I have an 07 that is very well taken care of 25K miles, 2.5" lift and 33's. My lower ball joints appeared to be a tad loose when I checked them with an iron bar. I replaced the uppers and lowers; the lowers were in extremely bad condition. The stock JK ball joint do not last long JMO.

 

And this will increase the off camber

 

As usual on this forum, finding an alignment specialist you trust is sometimes hard.

I asked because the I had it on the alignment rack at the dealer and they told me the ball joints were bad based on the camber measurements alone.

Camber: Left -0.5deg Right -0.9deg

However, I'm not sure I trust their diagnosis because they didn't talk about play in the joints. Ronjenx has posted the tolerances (~1mm) for play when doing the test where you use a prybar to apply force to the tire while the front end is jacked up at the axle. Running that test today.

Want to makes sure I investigate the other possibilities before committing to an expensive ball joint replacement.

 

Just a small lift will rotate the axle housing causing the camber to be off. You are on the right track, check it with a bar. The shop I went to let me go back while he checked the allignment.....independent shop just the way I like it.

 

that is nothing to worry about. screw the computer specifications.

 

Camber won't be affected by any lift. The C's are fixed on the axle house and is completely unaffected by any lift. I think you meant caster (with stock arms the axle will rotate with a lift).

 

When you lifted your JK the allignment program specs may not necessarily be what is needed to correctly allign it. An allignment teck that knows what they are doing will take your modifications into account and not just put it in the green.

 

OK. Balljoints confirmed bad. However, the inner C's could be bent too.

Back to the original question. Can someone measure on the inner C's on a brand-new D30? (same as 44? I think so)
