Make sure your axle is centerd (track bar) alingnment can be done with a tape measure. I have a casting line on my MTRs, so I went from casting line to casting line on the tires. Do this on the front and back, and when your done the front should be 1/4 tow in. Now your caster must me done also, adjust your Upper Control Arm mounts. You want to have a decent pinion angle but make sure that you have at least 3 degrees of caster on the inner C. This is how I did mine and it drives down the road great, It doesnt wander at all!!!!!!!!
