Fig. 1 Tightening clamp

Attaching the CV joint boot onto the outer body of the joint frequently
requires compressing or squeezing the boot. This produces a vacuum in
the joint boot, which may cause a crease to the inside when driving
(arrow).
For this reason, after installing the joint boot, vent it briefly by letting some
air in at the small diameter to balance the pressure and restore the correct
boot shape. Fig. 2 Venting CV joint boot
