How do you replace rear coil springs on a 86 Lincoln Town Car?

To replace the rear coil springs on a 1986 Lincoln Town Car, start by safely lifting the vehicle and securing it on jack stands. Remove the rear wheels and disconnect the shock absorbers to allow for suspension movement. Then, using a spring compressor, carefully compress the old coil springs and remove them from the lower control arms. Install the new coil springs, decompress them, reattach the shock absorbers, and finally, replace the wheels before lowering the vehicle.
