If

the rubber on the seal track spacer has

previously been compressed the hub end-float
can be checked by mounting a dial indicator

so

that the trace pin

rests in a preloaded condition on the nut.
Rotate the hub

check the end-float by pushing and pulling the
hub. End-float must fall within the limits given
in the previous instruction.
