They are super easy to replace..You can get brand new Bilstein Comforts/Sports for about $280 front and $200 rear and can be done in less than 30mins for the first side then 15mins for the other since you know everything.
This job is actually quite easy with the correct method and does not take long either. Start by loosing bolts on wheels, jack the car up and support it on quality stands.
Remove wheel and place new jack under the lower control arm. MAKE SURE to SUPPORT the weight of the car ON THIS JACK. You want the spring to
not move when you release the strut. Once the lower control arm is supported, unbolt the bolt on the top of the mount in engine bay. Push shock down (should do if worn) and now remove mount.
PS: If your shock is worn a bit, you may not
need to jack car up. You can do it all with wheels on ground. Just unbolt top mount bolt and push shock down. Now replace.
If shock is needed to be replaced continue. Undo the three bolts holding the shock in place. The upper mount will need a 19mm wrench to hold other the side from spinning. The bottom two are easy. Remove strut and support brake disk and associated items from hanging on the brake lines. Prop it up with a box or something....
Installation is reverse. My tip is to push the shock through the mount and secure using an old bolt to hold it in place. Now do the upper bolt FIRST because it holds it in the right place. Should be straight forward.
Safety is always #1 with anything suspension related, but as long as the lower control arm is supported, you should have no problems.
