P'D is the R.H. front wheel reading
- P'G is the L.H. front wheel reading
• Now raise the front of the vehicle until the
underside of the lift swing arm (or underside of
the bodyshell) is level with the tip of gauge T.Av.
605-04.
• Read off and note the new toe values, which are:
- P2D for the R.H. front wheel reading
- P2Gfor the L.H. front wheel reading
• Therefore a variation in toe exists of:
- P'D to P2D for the R.H. front wheel
- P'G to P2Gfor the L.H. front wheel
• This variation may be:
- towards toe-in
- towards toe-out
- or nil (if P'
=
P2)
• Refer the values obtained to the table below and
read off the corrections to be made to the existing
shims on each side on the vehicle.
