I know there was just a mass buy for these so there might be a lot of people with these same questions soon. I have a set of the stock length BC Broncos radius arms and I am having trouble figuring out the best way to install and get the caster I need.
Background: I am doing a complete frame up rebuild and have only the suspension and frame right now. body, drive train, etc.. or off. Rear springs are mounted. Suspension is Cage 3.5 springs front and rear. I have 2 degree bushings and 7 degree bushing on hand.
Here is my problem. When I installed the 2 degree bushing and had the radius arm adjusted for maximum caster. I was at 0 degrees caster once everything was installed on the frame. Is this because the frame is not weighed down yet? I was afraid I would not be able to get enough caster since the radius arms were already adjusted to the maximum so I order the 7 degree bushing. When I installed the 7 degree C bushings one radius arm sits 2" higher than the other (The old Bronco Lean) when I have the axle and radius arms on the ground.
Here's the questions: Do I need to try and fix the "Bronco Lean" or could I adjust the caster on each side independently with the adjustment in the radius arm? The problem I see with adjusting each side is that because of where the pivot point is on the radius arm this will push the axle out further forward on one side. I thought about adjusting the Heim joint on one side to correct this but there is not enough threads behind the nut to do so.
Does it matter if the axle is square with the frame? The way I see it the steering can be adjusted to drive straight. Hopefully this is all making sense.
Chuck?
