To replace the rear coil springs on a 2006 Buick Rendezvous, start by safely lifting the rear of the vehicle and securing it on jack stands. Remove the rear wheel and then unbolt the shock absorber to allow for more space. Use a coil spring compressor to safely compress the old spring before removing it from the lower control arm.
