I trust you are asking about the front struts and the question is actually a 2 part question. To remove the strut take the wheel off and start at the bottom. There are two bolts at the bottom of the strut; one is a thru bolt at the bottom of the strut fork that has a mating nut; the other is at the top of the strut fork that is a pinch bolt that screws into the upper fork. Remove those two bolts, then remove the upper strut bolt at the top of the strut in the engine compartment. You can then remove the strut assembly from underneath the car.You will need a strut spring compressor to remove the strut cartridge. DO NOT try to take it apart without the spring compressor or you can get severly injured. Do not use a cheap spring compressor because the compressor might break. If in doubt, take the strut assembly to a shop that has the right equipment and pay them to disassemble, remove and replace the strut cartridge. Its cheaper to pay a shop to do the removal and replacement of the strut cartridge than it is for you to buy the spring compressor. On most cars, you will have to do a four wheel alignment after you replace the strut cartridge because you will change the alignment geometry. You can't do that at home, so you'll have to take the car to a shop to have that done.Honestly, its just a better deal to have a reputable shop change the strut and do the alignment than it is to mess with the removal and run back and forth to get the cartridge changed and then have to get a alignment after that. Its not worth what you would save in doing some of it yourselfhope that answers your questions
