Hoist vehicle.
Inspect each boot for tear. A torn boot allows entry of
dust and water which can cause wear to steering rack
and pinion to produce noise as well as rust to result in
malfunction of steering system.
Even if boot tear is small, replace with new one.
Also, check each boot for dent. If there is a dent, keep
boot in most compressed state for some seconds to
correct dent.
Boots should be visually inspected for any damage, dent
and tear during every periodical inspection at specified
intervals and whenever vehicle is hoisted for any other
purpose.
