A few tips on doing this job.
-You’ll need a floor jack to raise the car so you can remove the wheel.
-Jack up the lower arm and compress the spring before you remove the 4 bolts securing the assembly to the car. Then lower the assembly and remove the large bottom bolt connecting the shock.
-Before you remove the assembly make a scratch or use a dab of paint to determine the correct orientation for reassembly.
-When reinstalling the assembly slide in the large lower bolt and then compress the spring and line up the holes by inserting a short metal rod or the smooth end of a drill bit before installing the bolts.
-The smart move is to chase the threads of the 4 holes to clean them up before you put the assembly back in. Clean up the old bolts or better yet buy new ones. You do not want to strip the nuts !! I purchased new bolts that were about 1/2" longer and ground off the treads on the first 1/2" to help me starting the bolts without stripping one. Ignore these steps at your own peril.
Did I mention that YOU DON"T WANT TO STRIP THE NUTS !
