Replacing struts is a pretty straighforward operation, but it's not for the average backyard mechanic since it requires special tools to remove them. If you insist on tackling the job yourself here is an idea of what's involved:
1- Remove the rear seat and trim panel.
2- Loosen the rear wheel lug nuts, raise the rear of the vehicle and support it on jackstands. Remove the wheel.
3- Detach the brake hose from the strut. Detach the ABS sensor wire from the strut.
4- Disconnect the stabilizer bar link from the strut.
5- Support the axle carrier with a floor jack. Place a block of wood between the jack head and the carrier.
6- Loosen the strut-to-axle carrier bolt nuts.
7- Remove the three upper strut-to-body mounting nuts.
8- Lower the axle carrier with the jack and remove the two strut-to-axle carrier bolts.
9- Remove the strut assembly.
10- Reverse these directions to replace the strut.
11- A 4 wheel alignment should be done.
12 - Good Luck
