DETAIL
Some Defender 90/110 power steering systems may exhibit a groaning type noise when turning the steering wheel rapidly toward the left. This noise
occurs momentarily as the steering wheel passes a given position. The given position differs from vehicle to vehicle, depending on the relationship of the
steering box input shaft to the steering wheel.
It has been identified that the noise is created by resonance in the outlet line of the steering box, triggered by the steering pump.
ACTION REQUIRED
Upon customer complaint of groaning noise when turning the steering wheel, follow the procedure below.
