I was looking at rear adjustable track bars on the JKS web site.
The notes for the track bars have these comments"
"4Vehicle must be equipped with CV-type rear driveshaft w/double cardan U-joint."
"7Vehicle must be equipped with slip yoke-type rear driveshaft w/ single cardan U-joint."
I've also seen RE's track bar brackets come in an angled for CV joints, and a straight version for slip yolk type. So my question is this: Why does the CV shaft require a different geometry track bar or bracket? The pinion angle is defined by the upper and lower control arms (which are fixed on stock TJ's). The track bar has no impact on this angle, so what difference does it make which track bar or bracket you use?
