Absorb rear-end shocks: When the S7 drives over bumps, potholes, or uneven roads, the bush’s rubber deforms elastically to absorb the shocks that the rear beam arm transfers to the chassis. This reduces the “jolt” felt in the rear cabin—making rides more comfortable, especially for backseat passengers.

Cut down suspension noise: The rubber material blocks direct metal-to-metal contact between the rear beam arm and chassis. It dampens vibration friction, stopping loud clunks, rattles, or squeaks from the rear suspension when driving over rough surfaces.

Stabilize rear wheel movement: While being flexible, the bush also provides enough rigidity to keep the rear beam arm in the right position. It limits excessive movement of the rear beam arm (e.g., when turning or braking hard), ensuring the rear wheels stay aligned—this helps with stable handling and even tire wear.

Fits These: All Haima S7 variants (matches the rear beam arm’s size, mounting bolt specs, and suspension movement range—confirm with VIN).

Won’t Fit These:

Other Haima models: Like Haima S5, 7X, or M3—different rear suspension designs, rear beam arm sizes, and mounting bolt patterns (bush can’t install or work).

Non-Haima vehicles: Even if similar in look, rear suspension layouts and beam arm specs differ (no functional fit).

S7 with modified rear suspension: Aftermarket lifted rear suspension kits or upgraded rear beam arms change the mounting position and movement range—original bush can’t adapt (loses shock absorption and stabilization effects).

Inspect every 40,000km: During routine maintenance, ask techs to check the bush’s condition—look for cracks, hardening, or bulging of the rubber. If the rubber is worn out, replace the bush immediately.

Clean regularly: When washing the car, wipe the rear suspension area (including the bush) with a damp cloth to remove road dust and mud—preventing abrasive particles from wearing the rubber surface.

Check for loose bolts: If you hear noises from the rear when driving over bumps, have techs check if the bush’s mounting bolts are loose—loose bolts reduce the bush’s stability and cause rattling.

Avoid extreme stress: Try not to drive over deep potholes, curbs, or rough terrain at high speed—excessive pressure can tear the rubber or bend the metal sleeve, ruining the bush.
