• 2002-2006 Mini Cooper Rear Driver & Passenger Side Suspension Strut Assembly

Product Structure

• The shock absorber assembly is composed of shock absorber, lower spring washer, dust cover, spring, shock absorber, upper spring washer, spring seat, bearing, top rubber, and nut.
• The total components of the shock absorber are four parts: front left, front right, rear left, and rear right. 
• The position of the lug (the horn connected to the brake disc) at the bottom of the shock absorber is different in each part, so when choosing a shock absorber assembly, be sure to find out which part of the shock absorber assembly is.

Working Principle :
   The shock absorber assembly is mainly used to suppress the shock and the impact from the road surface when the spring rebounds after absorbing the shock, and is used to counteract the torsional vibration of the crankshaft (that is, the phenomenon that the crankshaft is twisted by the impact of the ignition of the cylinder). 

   In the suspension system, the elastic element is vibrated due to impact. In order to improve the ride comfort of the car, a shock absorber is installed in parallel with the elastic element in the suspension to attenuate the vibration. The shock absorber is generally used in the shock absorber. Its working principle When the frame (or body) and the axle are subjected to relative motion due to vibration, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity through different pores into another cavity. 

When should the car shock absorber assembly be replaced?
1. Bouncing test: Press the car at the front or back corner of the car and release it quickly. If the car bounces over, the shock absorber is damaged and should be replaced.
2. The number of kilometers tested: the shock absorber should be checked regularly for 20,000 kilometers, it is recommended to replace the shock absorber for 80,000 kilometers, and the shock absorber must be replaced for 100,000 kilometers.
3. Tire friction: A damaged shock absorber will cause abnormal grooves on the tire surface and uneven wear. The shock absorber should be replaced.
4. Leakage of shock absorber: If the shock absorber leaks oil, the shock absorber should be replaced in time.

Detailed steps for replacement

1. Drive the vehicle into the station and park it correctly. Extend the lift support base into the bottom of the vehicle to ensure good contact between the support base and the support points of the vehicle body.

2. Take away the rain plate and wiper.

3. Remove the tire, and put the removed tire on the ground with the outer side facing up, and place the tire screws on the tool cart. 

4. Remove the screws on the connecting rod,the brake hose screws and the brake ABS cable. After removing the screws, keep and put them in the tool cart. (Note: Be careful not to damage the oil pipe and ABS cable. Do not seperate the brake lines, bleeding of the brake system is required when opening the brake lines.

5. Remove the tire rod using special tool.

6. Remove the vehicle height sensor. Be careful do not damage it.

7. Remove the ball head of the lower control arm. Until now the broken shock absorber assembly has been disassembled.

8. Before install the new shock absorber assembly, compare it with the old one.

9. Install the new one on the ateering knuckle assembly.

10. Assemble the shock absorber assembly and steering knuckle assembly back to the vehicle together.

11. Install back all the stuff you removed. (Note: tighten the tire bolts carefully, remember to debug the wiper.)

12. You can drive the car to check whether the installation is successful.
