V70 2.4 L5-2.4L VIN 61 B5244S (2001)
The mechanical element of the steering gear is lubricated with a semi-fluid grease and separated from the servo element with seals (6 and 9).
In a steering operation when one rubber boot is compressed and the other stretched air can pass from one boot to the other via the hollow steering rack
and the non pressurized part of the steering gear housing.
Operation of steering gear and fluid flow
A. Neutral position, the fluid can flow freely through the steering gear.
B. Steering left Fluid under high pressure flows from the power steering pump into the valve housing through the upper terminal. From the valve
housing, the fluid flows via the rotary valve into the external pipe in the steering gear and acts on the piston (20) and steering rack (10). See the
diagram found above in Design. The steering rack is therefore forced to the right.
C. Steering right Fluid under high pressure flows from the power steering pump into the valve housing through the upper terminal. Fluid flows into
the steering gear via the external pipe and acts on the piston (20) and steering rack (10). The steering rack is forced to the left.
