First you will need to rent a spring compressor, and hopefully you have an air impact to help aid in disassembly?
STRUT ASSEMBLY REPLACEMENT

Removal Procedure
1.Remove the nuts (1) and bolt (2) attaching the top of the strut assembly (5) to the body (3). 2.Raise and support the vehicle. Refer to LIFTING AND JACKING THE VEHICLE in General Information. 3.Place jack stands under the front crossmember. 4.Lower the vehicle slightly so that the weight of vehicle rests on the jack stands and not on the control arms.

NOTE: Care must be exercised to prevent the drive axle joints from being over-extended. When either end of the shaft is disconnected, over-extension of the joint could result in separation of the internal components and possible joint failure. Drive axle joint boot protectors should be used any time service is performed on or near the drive axles. Failure to observe this can result in interior joint or boot damage and possible joint failure.
5.Remove the tire and wheel assembly. Refer to TIRE AND WHEEL REMOVAL AND INSTALLATION in Tires and Wheels. 6.Remove the brake line bracket.

7.Scribe the strut flange. Refer to STRUT AND KNUCKLE SCRIBING. 8.Remove the bolts (6) and the nuts (2) attaching the strut (1) to the steering knuckle (3).
NOTE: Care should be taken to avoid scratching or cracking the spring coating when handling the front suspension coil spring. Damage can cause premature failure.
IMPORTANT: The steering knuckle must be supported in order to prevent axle joint over-extension.
9.Remove the strut (1) from the vehicle.

NOTE: Care should be taken to avoid scratching or cracking the spring coating when handling the front suspension coil spring. Damage can cause premature failure.
Installation Procedure
1.Install the strut (5) into position and install the nuts (1) and one bolt (2) connecting the strut (5) to the body (3). Hand tighten the nuts and the bolt.

4.Tighten the nuts (1) and bolt (2) attaching the top of the strut (5) to the body (3).
Tighten
Tighten the nuts to 25 N.m (18 lb ft).
Tighten the bolt to 25 N.m (18 lb ft). 5.Install the brake line bracket. 6.Install the tire and wheel assembly. Refer to TIRE AND WHEEL REMOVAL AND INSTALLATION in Tires and Wheels. 7.Inspect the front wheel alignment. Refer to MEASURING WHEEL ALIGNMENT in Wheel Alignment.

SUSPENSION STRUT DISPOSAL

CAUTION:Use the proper eye protection when drilling to prevent metal chips from causing physical injury. 1.Clamp the strut in a vise horizontally with the rod (1) completely extended. 2.Drill a hole in the strut at the center of the end cap (3) using a 5 mm (3/16 in) drill bit. Gas or a gas/oil mixture will exhaust when the drill bit penetrates the strut. Use shop towels in order to contain the escaping oil. 3.Remove the strut from the vise. 4.Hold the strut over a drain pan vertically with the hole down. 5.Move the rod (1) in and out of the tube (2) to completely drain the oil from the strut.
