Thread: A question on clearance

So you may be wondering what clearance. My mule is lifted just a wee bit. So what I want to find out is what the std clearance between the bump stops and the axles. Also what the std bump stop lengths is too. Been reading some about castor angles . Given the way the steering is and the amount of lift this has my suspicions have been raised. With the way the front has been done I can rotate the diff to get a better pinion to drive shaft angle. But this of course efects the castor angle.

This makes rotating the diff possible as the arms are adjustable. By simply lengthening or shortening the centre one. At the moment the front shaft is at a fair angle and of course even worse when the axle drops down.

Yes, with the 3-link front end you lose the inherent tendency of the original suspension to maintain the front diff input angle regardless of suspension height, but it DOES maintain caster angle regardless of height (or, at least, shifts it less; the upper and lower arms would need to be the same length for the geometry to stay the same throughout susp travel), whereas the original design causes the caster angle to become more negative as the springs lengthen. If you rotate the axle forward to reduce the diff angle, you will of course need to rotate the swivel housings (by slotting the holes) the opposite direction to regain caster. I'd suggest you would be best to get your diff angle sorted first, then have the caster angle measured and then slot and rotate the swivel balls to get the caster back to spec.
