Are strut mount fitting kit and suspension strut support mount mounting set the same thing?

Yes. "Strut Mount Fitting Kit" and "Suspension strut support mount mounting set" refer to the same car part. Other common names include Suspension strut support mount mounting set, Suspension Strut Support Mount Mounting Set, Mounting Set, suspension strut support mount. The part is the same regardless of which name is used.

Can I replace just the top mount bearing without changing the shock absorber?

Yes, if the shock absorber is still in good condition. However, once the strut is removed and the spring compressed for bearing access, fitting a new shock absorber at the same time saves significant labour cost on the next service.

Do I need a wheel alignment after replacing top mounts?

Yes. Removing the strut affects camber and caster. Always carry out a four-wheel alignment after strut or top mount replacement to restore correct geometry and prevent uneven tyre wear.

Is a spring compressor essential for this job?

Absolutely. The compressed spring stores enormous energy — releasing it without a proper compressor can cause severe injury or death. Do not attempt this job without the correct safety equipment.

What causes top mount bearings to fail?

Corrosion from road water ingress, wear from constant steering movement, and fatigue of the rubber mount from years of vibration loading are the main causes. Driving on poorly maintained roads and kerbing accelerate wear.

How long do suspension top mounts last?

Typically 60,000-100,000 miles, though this varies by vehicle and road conditions. They should be inspected whenever shock absorbers are replaced and at every major service.

Strut Mount Fitting Kit buying guide — what to know before you buy

The suspension strut support mount (top mount) is the bearing and rubber assembly that sits at the top of the MacPherson strut, connecting the strut to the vehicle body. It performs two functions: it allows the strut to rotate as the wheels steer, and it isolates the body from road noise and impacts transmitted up the strut. When the upper bearing seizes or the rubber degrades, you get knocking over bumps, heavy or notchy steering, and uneven tyre wear. Sachs, Febi Bilstein, and Meyle supply complete mounting sets including the bearing and rubber mount for most vehicles. Replacement is normally carried out alongside new shock absorbers and springs for a complete strut overhaul.

Symptoms of a failing top mount

A worn suspension top mount affects ride comfort, steering feel, and wheel alignment. Identifying the fault early avoids accelerated tyre wear and deteriorating handling.

Single knock or clunk over bumps, potholes, or speed bumps
Graunching or creaking when turning the steering wheel at low speed
Steering feels heavy or notchy in one direction
Vibration transmitted through the steering wheel over rough roads
Visible rust or deterioration at the top of the strut tower

Components of the mounting set

A complete top mount kit typically includes the upper bearing, the rubber mount pad, and a jounce bumper or dust cover sleeve. Some kits also include the spring seat. Fitting all components together ensures correct load distribution and avoids mixing old and new parts with different levels of wear.

Upper bearing: allows strut rotation during steering
Rubber mount pad: isolates vibration between strut and body
Jounce bumper: limits suspension travel to protect the strut
Dust cover: protects the shock absorber shaft from dirt

Replacing the top mount

The strut must be removed from the vehicle and the spring compressed safely before the top mount can be accessed. A proper coil spring compressor is essential — improvised methods risk catastrophic spring release. The spring nut must be torqued precisely; consult the vehicle-specific torque specification.
