A key part of any suspension system, having fully-working shock absorbers will ensure a smooth and safe drive. The pump-like devices keep a vehicle’s tyres in contact with the road by controlling the rebound of its suspension springs – as long as the tyres remain in contact with the road, steering, handling and braking will be at optimal levels.

Here we've outlined the step-by-step breakdown of checking or replacing your Mini's front suspension & replacing shock absorbers:

  • Jack up the front of the Mini under the subframe (not bodywork) stabilise with axle stands.
  • Remove the road wheels.
  • Check the wheel bearings for play, if play is excessive adjust the bearing preload or replace
  • Check the shock absorbers for oil leaks or corrosion, replace if necessary.
  • Check the upper and lower ball joints for excessive play and for tightness when turning the steering, re shim or replace as necessary.
  • Check for excessive movement in the track rod ends and steering rack, replace as necessary.
  • Turn the steering by twisting the swivel hub, observe any notchy feeling or free play.
  • Check the condition of the lower arm bushes and tie rod bushes - replace as necessary.
  • Check the tie rods for bends or corrosion, replace as necessary Check for excessive play in the upper arm bearings, replace as necessary
  • Visually inspect the knuckle joint rubber cover and cup for damage or deterioration.
  • Visually check the suspension cone for excessive compression or corrosion, replace as necessary.
  • Visually check the bump stop and rebound buffer for condition, replace as necessary
  • Re-grease the upper and lower ball joints.
  • Refit the road wheels and tighten the wheel nuts.
  • Drop the mini back onto the ground and torque the wheel nuts.

Procedure for replacing the front shock absorber :-

  • With the Mini jacked up at the front and stabilised on axle stands, and the road wheel removed.
  • Undo the upper and lower securing nuts and remove the washers, remove the shock absorber and replace with a new unit in reverse order (always replace shock absorbers in pairs - Axle set)

Procedure for replacing the rear suspension :-

  • Chock the front wheels and put the car in reverse gear. Jack up the rear of the car under the subframe (not by the bodywork!) and stabilise with axle stands - remove the road wheels and release the handbrake.
  • Check the wheel bearings for excessive play - adjust or replace as necessary
  • Check the radius arm and spindle for excessive movement - replace the spindle & bushes or exchange the arms for reconditioned ones, if play is excessive.
  • Check the shock absorbers for leaks or corrosion - replace if necessary (replace in pairs per axle)
  • Lift the wheel up to test the shock absorber, there should be some resistance when lifting, if there is very little or no resistance , then the shock absorber will need replacing (replace in pairs per axle)
  • Check the knuckle joint rubbers and plastic cups - replace as necessary
  • Visually inspect the suspension cones for compression - replace if compressed or corroded.
  • Re-grease the radius arm spindles
  • Refit the road wheels and tighten the wheel nuts.
  • Drop the car back onto the ground and torque the wheel nuts

Procedure for replacing the rear shock absorbers :-

  • With the rear of the Mini jacked up and stabilised with axle stands and rear wheels removed, put the jack under the radius arm behind the brake assembly.
  • Jack up the radius arm to compress the shock absorber.
  • Unscrew the top and bottom securing nuts and remove associated washers and bushes.
  • Slowly lower the radius arm to release the shock absorber and then remove the shock absorber from the radius arm.
  • Procedure for replacing the shock absorber is the exact reversal of the removal procedure.
