When you remove your Panhard Rod (either Front or Rear) then the inevitable will happen. You will find one of the bolts has siezed or cold welded itself into the Bush.
You WILL end up cutting one off. Therefore make sure you have the correct parts to hand when you start.
This set consists of a pair of High Tensile Bolts (M12 x 70mm METRIC FINE) and a single matching Nyloc nut (one end of the rod needs a nut, the other has a captive nut already welded into the mount)
Just by buying these should ensure that yours undo without any problems!
