Begin CV joint inspection (Figure 38-11) by checking
the condition of the boots. Splits, cracks, tears, punctures,
or thin spots caused by rubbing call for immediate boot replacement. If the boot appears rotted, this indicates im
proper greasing or excessive heat, and it should be replaced.
Squeeze all boots. If any air escapes, replace the boot.
If the inner boot appears to be collapsed or deformed.
venting it (allowing air to enter) might solve the problem.
Place a round-tipped rod between the boot and drive
shaft. This equalizes the outside and inside air and allows
the boot to return to its normal shape.
