Microsoft Paint Aided Design. Trying to get the trackbar set up to have less bump steer. Original position on left. Ideal-ish position on right with a new track bar frame mount. Still had to make a new trackbar.
Both circles move in same arc, means they shouldn't have bump steer. You want the ride range (up and down about 4") to have the same distance between the two circles so it doesn't bump steer on the road. Off-road it's less important, if it's slow going off-road stuff.
