Thread: 2"+ lift vibration

The other point mentioned was front radius arms, these correct castor angle which is lost by the lift but effects the pinion angle, in my opinion the best way to fix this is by fitting slotted swivel hubs, this corrects the castor angle and dosn't interfer with the pinion angle

fully agree with the caster,,, but its driving perfict,, no light steering,, wonering,, nothing, so that will be down the track, i need to sort out the vib first, and did you say that Hardy Spicer are local to me,, do you no were??

You would still get vids, as the slotted hub only correct castor angle, the slotted bushes in the radius arms have rolled the diff housing to give some relief on the uni joints but is not the best way of fixing the problem, a double cardon or wide angle uni joint is the best.
