Please help.
I got my Lightening bow back from the guy I sold it to and I just noticed that the right cam leans where the left one doesn't. I checked all the rigging. Axle is perfectly straight. I even swapped the right limbs (top for bottom) thinking they might be a hair different in strength. No change.
Anybody got any suggestions?
Thank you.

You sold a bow to someone, and the guy returned it...?
You are TOO forgiving.
Since you've already taken it apart, just do the obvious...
1. Check the hole in the lims carefully for seperation.
2. Check the loosness of the cam bearings.
3. Check the fit of the bearing in the cam.
Sounds like the bow may have been dry fired. If that's case...I'd send to back to Darton with an explanation.

I am not a dealer. I sold it to a friend who never shot it. However, I found the problem. There is no wear on anything as it has never been dry-fired and only shot a few times. I found the problem. I took the limbs off and there are special die-cut plastic shims that go between the limbs and the face of the riser. They were fine but there was another die-cut shim in there that was obviously modified. It looks like they took a sissors and trimmed an original shim but it did not cover the entire mating surface where the limbs touch the riser. So, the limbs would want to twist. I took those extra pieces out and everything is fine. Do not know why they were in there. The only difference now is that the power stroke is 1/64" shorter. No big deal there.

Good you found what it was, some manufacturers shim limbs ie. it is important for both sides of a bow to be balanced. By shimming one side it will bring the limb up to the same strength as the other side. Never remove all shim material on any bow the limb will bind and crush every time FYI I know you did not do this but others need to understand these plastic shims are very important.
