FITTING INSTRUCTIONS
1. Put the car into gear or park and apply the hand brake, loosen the front wheel nuts on one side, raise the
vehicle on a trolley or bottle jack under the axle and then support the vehicle with an axle stand under the

absorber out through the hole in the inner wing.

the vehicle you are changing as the springs are normally handed.
