SECTION: 3B


SUBJECT: POWER STEERING SHUDDER INLET HOSE AND PIPE ASSEMBLY REPLACEMENT


MODELS/YEARS: 1988-91 CUTLASS SUPREME WITH 2.8L AND 3.1L


CONDITION: Some 1988-91 Cutlass Supreme Models with 2.8L (RPO LB6) or 3.1L (RPO LHO) V-6 engines assembled prior to VIN MD329431 may exhibit a slight power steering shudder condition noted during static or low speed turning maneuvers. This condition may be perceived as a disturbance felt and heard by the vehicle operator through the body structure and steering wheel.

CORRECTION: Replace the existing power steering inlet (pressure) hose and pipe assembly with new assembly noted below by model year, with internal tuning cable and high expansion hose material.
