Common Steering Issues It May Address

- Hard steering after startup or inconsistent assist
- Steering noise related to worn rack seals or internal bypass
- Poor return-to-center caused by a worn steering gear or related hydraulic restriction
Installation Notes
For the listed Buick Park Avenue, Buick Riviera, and Oldsmobile Aurora applications, follow the vehicle-specific notes closely. CARDONE recommends installing an in-line filter, using the suggested OE fluid, and flushing the hydraulic power steering system during installation. Proper bleeding is important to remove air from the system and reduce pump whine after replacement. Verify alignment and inspect return-line routing if the steering does not return to center.
Quality Assurance
Each CARDONE Electronic Power Steering Rack and Pinion is remanufactured to rigorous quality and performance standards, then factory test driven to confirm operation under demanding conditions. Rubber sealing components are replaced, a specialized lubricant is applied, and the unit is finished with a protective coating to support long-term durability. The remanufacturing process also reduces energy and raw material use compared with producing a new part.
