My guess would be physics? The weight is being transfered to the down hill wheel (gravity) and that wheel is hooking up; compressing that side of the axle and further unloading the uphill side.
I don't often experience this situation but then again I run full droop so my downhill side is already fully compressed.

Try lighter springs in the front.

Well, you might try running a bit of toe out. That will have your inside tire turning at a sharper angle than the outside...and hopefully keep from lifting that inner tire.

it doesnt harm my crawlers ability at all or does the postive effects outweigh the negative. how much toe out? only a few degrees be enough?

That's really something that you'll need to mess around with. Adjust the toe slightly, then try the climb that you are concerned about....

try running a little negative caster, it will help with the tire maintaining more of a flat contact patch when digging uphill. Note: I did mean CASTER, not Camber. Roll the axles back a little to get some caster.

Yep, good idea as well!

BTW, I don't think any of these trucks have adjustable camber....well, they aren't supposed to.

ok i tried having toe out and it didnt really help. at least i didnt notice it./ i usually run rovers on 1 in wheels with nova 2.2 dd and i switched over to my chisels with stock memory foams on titus wheels and it didnt do it. foams maybe the cause?

When you are testing out a new setup, you should really only change one variable at a time...
