	Checking
1.1	Remove bottom section of soundproofing	Vehicles with diesel engines	AR94.30-P-5300T
1.2	Remove engine compartment paneling	Vehicles with gasoline engines	AR61.20-P-1105T
2	Check bellows (11)	Never check bellows by pressing in or around raised bead as this will damage bellows and eventually cause leaks. Perfect sealing of the bellows is absolutely vital for correct functioning of the rack-and-pinion steering, so perform the visual inspection as follows: Raise vehicle at front axle. Extend the bellows by turning the steering onto left wheel lock or right wheel lock and check for damage (cracks, chafing marks and intrusions) in the process, install new bellows if necessary.
