So im trying to set the caster on my jeep after installing my long arms. Is it normal for the caster to vary a few degrees between sides?

 

No. A couple tenths, maybe.

 

Should have a bit more caster in the right side to compensate for the crown in the road.

As to how much, you'd have to consult the manual or alignment shop.

7* to 8* is factory spec.

 

I had mine done by a shop and I think there was a 0.2* difference between the right and left.

They set me at 4.8 left and 5.0 right. I would've liked a bit more but it works and left me with a good pinion angle.

 

This. ^^^

 

I'll haft to re check this then. I'm measuring of the flat spot on the bottom of the knuckle, one side I'm dead on 7*, the other I'm at 10*.

 

Mine is off by like 4° from one side to the other. Wish I would have noticed that before welding on gussets, control arm brackets, sleeves and a truss. LOL luckily mine is a trailer queen.

 

Lol, I Had to put on new brackets cause the po smashed them. This jeep is going to be on the road most of the time. So I'm hoping I'm just on unevel ground and bits throwing off my measurements.

 

I thought about cutting the inner-c and turning it to match but way too much junk welded to them to do that now. I might cut my true loose and see if I can twist the whole passenger side tube.

 

That might do it. Do you think if my lcas weren't the same length that could throw it off ??

 

No, all that would do is pull one side back a little bit.

 

Thats what I figured.

 

Well I just went out and checked it, drivers sides dead on 10, passenger side is just off 9. before I was getting 10 and 7. I'm not on the most level ground!
