• The shock absorber top mount (sometimes called “strut mount” or “upper mount”) attaches the top of the front damper/strut assembly to the vehicle’s body/strut tower. It supports the spring/damper load, allows steering movement (via the bearing), and isolates noise/vibration.
• Over time, the rubber mount may degrade, the bearing can bind or wear, hardware may corrode — leading to poor ride, noise, loss of precision.
• The overhaul kit replaces the mount, bearing and all relevant hardware so the top of your front suspension is restored to correct specification — improving longevity, ride quality, handling, and eliminating common wear symptoms.

• Knocking, creaking or clunking from the top of the strut tower when driving over bumps or turning the steering wheel.
  
• Steering or handling feel degraded: less precision, vague feedback, increased body roll, front-end wander.
  
• Suspension ride quality worsened, front-end noise or vibration transmitted into the cabin.
  
• You are replacing front shocks/struts: since the top mount must be removed for that job, it’s efficient to replace the mount/bearing/hardware at the same time.
  
• Mount or bearing visibly worn: If inspection shows the mount rubber cracked, bearing flattened or play exists, the overhaul kit is justified.

• The rear shock absorber top mount secures the top of the shock or strut assembly to the vehicle body or rear suspension tower. It ensures the damper is correctly located and loaded, and helps absorb vibrations, maintain correct geometry and isolate noise.
• Over time, mounts, washers, nuts and associated hardware fatigue – the mount may sag or shift, washers may wear, the nut may loosen, the bearing (if present) may wear. This reduces suspension precision, can introduce noise (clunks, creaks) and affects handling.
• This kit replaces the top mount nut, washers, mount components and related hardware — restoring the top of the damper assembly to like-new spec, which supports ride quality, handling, durability and quiet operation.

• Knocking or clunking noises from the rear strut top area when accelerating, decelerating or going over bumps.
  
• Poor ride quality at the rear, increased vibration or a feeling of looseness in the rear suspension.
  
• Inconsistent handling or rear feel: e.g., rear end doesn’t feel as controlled or stable in corners.
  
• You are replacing/rebuilding your rear dampers/shocks or springs: since the top mount hardware is removed anyway, replacing it is efficient and recommended.
  
• Visible damage or wear: If mount washers are deformed, nuts show signs of loosening, or the mount has shifted — an overhaul kit helps restore it properly.

Why Replacement Matters:

• Restores rear suspension integrity & performance: The top mount plays a key role in how the rear damper responds. A worn mount allows movement or misalignment, reducing tyre contact and degrading handling.
  
• Eliminates noise and improves comfort: A compromised mount is often the source of rear knocks, rattles or increased harshness — replacing the kit removes this weak link.
  
• Prevents further damage: If the mount hardware fails, the stress transfers to other components: damper shaft, body mount, spring seat — renewing the top mount stops further failure.
  
• Cost-effective when servicing: When the shock assembly is out for service, installing the full mount kit avoids future labour for what is essentially an ageing item.

• The front shock absorber (strut) top mount (sometimes called “strut mount,” “upper mount,” or “mount cap & bearing”) is the part that mounts the top of the front damper/strut to the vehicle’s body (strut tower). It carries spring and damper load, provides a secure connection to the chassis, and often includes a bearing to allow the strut to rotate with steering movement.
• Over time, the top mount’s rubber or elastomer may degrade, the bearing may develop play or noise, the mount plate may shift, washers/nuts may loosen, dust covers may deteriorate. This results in increased noise, worse ride/handling, and possible mis-alignment of the strut.
• This overhaul kit replaces the mount, bearing and all relevant hardware so you restore that top mount area to like new, ensuring proper load path, better durability, reduced noise and proper steering/handling characteristics.
  
  

• Clunking, knocking or creaking noises from the front strut-tower area when going over bumps or during steering input — a typical symptom of a worn mount or bearing.
  
• Steering feel or front suspension feel has degraded — loose, vague feel, or mis-alignment under load (cornering) can be caused by mount movement or bearing play.
  
• Ride comfort has worsened — a degraded mount transmits more road vibration or noise into the cabin.
  
• You are replacing the front shocks/struts or doing front suspension work — since the top mount is removed/loosened for such work, renewing the mount and hardware at the same time is highly recommended.
  
• Visual inspection may show a cracked or separated mount rubber, bearing play, rusted or worn nuts/bolts, or installer notes of mount movement when the top is pushed.

• The top mount (upper mount) of the shock/strut assembly is critical: it secures the top of the damper to the vehicle’s body/strut tower, supports the spring/damper load, and ensures correct alignment and isolation of vibration or noise.
• Over time, mounts/washers/nuts can corrode, loosen, rubber can deteriorate (if included), or tolerances may degrade, leading to movement, noise, vibration or alignment issues. Replacing the full kit restores the interface — ensuring the shock absorber is properly anchored, loads are contained, and suspension geometry/behaviour maintained.

• Clunking, knocking or popping noises from the rear strut top area when driving over bumps, or when the suspension unloads/loads.
  
• Excessive vibration or “thunk” from the rear when cornering or braking — indicating the top mount might be giving way.
  
• Poor rear suspension feel / looseness in the rear – drifting feel, less precise handling than before.
  
• Visual signs of wear – if you inspect the top mount area and find nut is loose, washers/show signs of corrosion, the cap or mount plate is damaged, or the mount has had previous repair.
  
• During a shock absorber/strut replacement or rear suspension refresh – if you have the unit removed, it is highly efficient to replace the top mount kit at the same time, rather than later.
