Shock Absorber Replacement

Please refer to manufacturer’s manual for complete removal instructions.
Recommend replacement of parts by qualified person.

4WD Shock Absorber replacement

Step 1: Remove shock absorber

  1. Make sure the vehicle is properly supported
  2. Removal of wheel is sometimes required (refer to manufacturers manual)
  3. Loosen the fasteners at the top and bottom of the shock absorber.
  4. NOTE the order and position of rubber bushes and metal support washers that are removed.
  5. Slide the shock absorber away from the mountings and remove it from the vehicle.

Step 2: Refit shock absorber

  1. Fit new rubber bushes to new shock absorber making sure bushes and support washers are replaced in the same order as removed and locate the unit on the vehicle. Fit the other half of the bushing/washers to the mounting and attach the fastener.
  2. Make sure you tighten mounts to the manufacturer’s specification.

4WD Strut Type Shock Absorbers replacement

Step 1: Remove strut assembly

  1. Please refer to your vehicle manufacturer’s manual for instructions on removing struts assemblies as
  2. Strut assemblies can be attached in a number of different ways,

Step 2: Compress the spring

  1. Mount the strut assembly securely in a vice ensuring that you do not strut body, compress spring coils using special spring compressor tool

Step 3: Remove the spring

  1. Note the position of the top mount (mark if required) Loosen and remove the locking nut that secures the top mount to the shock absorber shaft.
  2. Remove the top mount and the upper spring insulator, protective sleeve, bump stop, compressed spring and lower spring insulator

Step 4: Replace any damaged protective sleeves, bump stops, spring insulators

  1. replace lower spring insulator, compressed spring, bump stop, protective sleeve to new strut unit, locate the top mount to the strut shaft and
  2. Tighten the securing nut, Loosen the spring compressor while guiding the spring into its position within the upper mount and lower seat.

Step 5: Refit the strut assembly

  1. Please refer to your vehicle manufacturer’s manual for instructions on replacing struts assemblies


  • Some struts require the fitment of a special ring spacer below the lower spring seat. To determine if it is required,
  • Measure the distance of the spring seat and strut bottom mount with and without spacer, compare distance to old strut and determine if it is necessary to use spacer
  • #if spacer is used when it is not required some vehicle body lift may result
  • #if spacer is not use when required some vehicle body drop may result
  • DO NOT use any form of clamp on the shock absorber shaft as damage will result TO SHAFT AND SEAL AND WILL VOID WARRANTY


Q: What is a shock absorber and its specific function?

A shock absorbers is basically an oil pump with a restrictor valve. Shock absorbers control the spring’s rate of travel through both its compression and rebound stages of each suspension stroke. The compression and rebound valves inside the hydraulic fluid filled

Shock body slow down the spring’s movement. 

Shock absorbers perform 2 basic functions, they dampen the oscillations of the springs (coil and leaf) or the twisting action of torsion bars. That is they control the movements of the above forms of suspension springs found in all 4WD vehicles and they keep your tyres in contact with the road surface.

Gas Pressurised and hydraulic fluid shock absorber.

Low pressure nitrogen gas reduces the likelihood of oil aeration and shock fade. 

Micro-cellular foam insert and hydraulic fluid Premium shock absorbers. 

Micro-Cellular closed cell foam insert maximises cooling efficiency.
Greater oil capacity and more surface area maintains lower operating temperatures.

Q: What are the signs of a worn shock absorber? 

  1. Leaking hydraulic fluid around shock absorber body
  2. Uneven tyre wear
  3. knocking noises or rattles
  4. The vehicle is swaying and/or requires constant steering corrections
  5. Excessive bouncing over bumps 

Q: What lift will shock absorbers provide?

Shocks absorbers do not lift a vehicle, only provide ride comfort and safety.

Q: What is the warranty?

2 Years/40,000km. 

Q: foam cell strut/shock absorber shaft does not extend. Is it faulty?

Foam cell struts/shock absorbers are not gas pressurised as a result the shaft will not extend on its own. This does not mean the part is faulty
