I chased this ALL OVER... since rear panel was dinged in, i figured it was axle
put'er on jackstands per CHP rules, won't axles, turned straight & true.
DS was wobbling up & down.
Ray & I did a tranny mount, a front U-joint, and a new rear seal.
still wobbly.
Robert / Griffin Transmission did a o-ring on the speed sensor, and worked a kink out of the front joint.
still just a tiny bit.
had DS balanced, and new rear u-joint.
still just a bit.
got rid of the big jeep rims & tires (they were on with spacers)
put on OEM rims & tire sizes.
and BADDA bing BADDA boOM!!
fixed it, the ole girls runs out SMOOOTH...
so the moral is...keep spending money till you get it fixed
