ACDelco Steering Gear Housing Bushing
ACDelco Steering Gear Housing Bushings
The steering gear housing bushing is a small part with a big job. It secures the rack-and-pinion or steering gear assembly to the chassis or subframe while isolating the housing from road shock. When these bushings harden, crack or compress, drivers often notice clunking over bumps, vague on-center feel, or steering wander. ACDelco, General Motors' parts brand, offers these bushings across several product tiers, so you can match the repair to the vehicle and the job.
Product Lines Within the Category
ACDelco's steering gear bushings are organized around its tiered portfolio. Within this category you will find:
- ACDelco Professional (Gold): Premium aftermarket replacements built to meet expectations for fit, form and function. Examples include rack and pinion mount bushings such as the 45G24074 and 45G24075 rack bushings and the 45G24060 driver-side bushing, which uses a metal sleeve and rubber design to support alignment, stability and durability.
- ACDelco Advantage (Silver): A value-focused line for dependable, economical repairs. The 46G31000A rack and pinion mount bushing is designed as a direct-fit replacement that helps isolate the steering rack from the chassis and reduce transmitted noise and vibration.
- ACDelco GM Genuine Parts: Bushings such as the 20908399 are designed, engineered and tested for GM vehicles, with a precise fit for easier installation.
Why ACDelco Stands Out Here
The main advantage is GM heritage. Many ACDelco bushings correspond directly to GM original-equipment part numbers, which matters because rack mount bushings are highly vehicle-specific. Shape, durometer and sleeve geometry vary widely between a full-size truck and a compact sedan. Some Professional-grade parts are also described as improved designs that can help avoid replacing an entire rack when the bushings are the actual source of play. Select Professional bushings are manufactured at TS 16949-certified facilities, a quality standard widely used in the automotive supply chain.
ACDelco also supports the wider steering-gear repair. Alongside mount bushings, its catalog includes pinion shaft seal kits that combine a bushing with seals, gaskets or snap rings, which is useful when a leaking or worn steering gear needs a more complete rebuild.
Shopping Considerations
- Confirm the exact application: Match the part number to your year, make, model and steering gear type. Some bushings are side-specific, such as driver-side units.
- Choose the right tier: Professional parts suit owners who want a high-quality alternative to OE, while Advantage parts suit budget-conscious repairs on daily drivers.
- Inspect related components: Check tie rod ends, inner tie rod bushings and the subframe mounting points while the steering gear is accessible.
- Plan for alignment: Loosening or lowering the steering gear can change steering geometry, so an alignment check after installation is good practice.
