Hello, First of all I understand this topic is over saturated with repetitive question but after reading through the forum my question was not answered. Im lucky enough to be working at a shop where I have access to lifts and a very nice alignment rack. I have adjustable bushings for caster and camber and after rebuilding my steering linkage I went to perform an alignment. Toe was easy, but adjusting camber and caster was a bit of a trip. The bushings only have a certain range of adjustment they can perform, for both camber and caster and are performed together. Right now my measurements are: Camber: -.3. Caster: 7.0 driver and for passenger Camber: -.6 Caster: 5.6. Here is where the issue lies, first of all camber is massively out of spec, that can be corrected with either rotating the bushing or replacing the bushing all together. Second issue is the caster, in CO our roads are slanted to the right for drainage, so during our alignments we slant the caster .5 to 1 degree towards the left to correct for it. Here is where it gets interesting and it lies within the measurements.
Driver side:
Camber minimum: -.03. Caster @ 7
Camber maximum: -2.1 @ caster 6.5
Caster maximum: 8.6
Caster minimum: 6.5.
Passenger Side:
Camber minimum:-.04 @ caster 6.7
Camber maximum: - 2.3 @ caster 4.9
Caster minimum. 4.7
Caster Maximum: 6.8
1st, these measurements were taking with the axle up in the air, and differ from the measurements and adjustments made with the front end resting on the ground. I jacked up the axle by the I beams, not the frame. We can see with getting the camber as close as we could to factory which is 0 ( most important due to camber being a wear angle) the caster is a 1.4 degree split towards the right causing the vehicle to pull right. On top of the 1.4 degree split we already have we want a .5 to 1 degree split to get the vehicle to drive straight. If we completely ignore camber and focus on caster, our minimum on driver side is 6.5, and our maximum on the passenger side is 6.8, not even close to get a straight driving vehicle with 2 degrease of camber. My question is, will replacing the bushing help my caster split? or do i have an issue somewhere else. here is an interesting picture on alldata I found. I will be remeasuring tomorrow.
