Suspension & Steering

Struts, shock absorbers, control arms, ball joints, tie rods, bushings and wheel hub assemblies to General Motors original specification.

Suspension geometry is engineered, not assembled. Bushing durometer, ball joint preload and control arm bush bore position determine where the wheel sits through its travel, and therefore how the vehicle tracks, how the tyres wear and how the electronic stability system interprets what the vehicle is doing. Softer aftermarket bushings feel acceptable on delivery and let geometry drift under load within a year. We supply steering and suspension components to the original GM specification, including hub assemblies with the correct integrated speed sensor.

Suspension geometry is a chain: one worn ball joint or bushing changes camber and toe at the contact patch and wears tyres unevenly.

What we supply in this category

Symptoms that point to this system

Common complaints

  • A clunk over expansion joints or speed bumps
  • Steering that wanders and needs constant correction
  • Uneven or feathered tyre wear on one edge
  • A droning hum that changes pitch when cornering
  • Alignment that will not hold after being set

Before you order

Replace suspension components in axle pairs where the joint carries load. A new strut opposite a worn one produces a corner-to-corner imbalance that the stability control system will read as a persistent yaw offset.

Vehicle coverage

We supply Suspension & Steering components across every General Motors division:

Questions we are asked about Suspension & Steering

Does the wheel bearing come as a complete hub?

On most modern GM platforms, yes. The bearing, hub flange and speed sensor are supplied as a sealed assembly and are not serviceable separately.

Is an alignment required after this work?

Any part that positions the wheel — control arm, tie rod, knuckle or ball joint — requires a four-wheel alignment afterwards. Struts on strut-type front suspension also affect camber.
