You will need to get a pair of spring compressors. I rented mine from autozone for $30.00. They will refund your money if you bring them back undamaged. Also new springs and new top plates that hold the top of the spring in place. I also replaced my struts, since the whole thing comes out as one unit. 4 bolts to remove, 2 at the bottom wheel area, and 2 hiding in the rear trunk panel. I replaced the rear struts and springs, not the front. Get the whole unit into a good vice, compress the spring, remove the top nut, and uncompress and remove. If you buy all new you can just toss the old unit. My cost if I remember correctly was about $230 dollars altogether for both rear units. 2 springs - $60.00, 2 top plates - $50.00, and 2 struts - $120.00.
replacing coil springs, 2002 ford explorer
A 2002 Jeep Wrangler has coil springs.
Yes
I don't think so.
take the old ones out and put new ones in
If you are trying to drop the front end 4 inches I would recommend replacing the stock front spindles with 3 inch drop spindles and replacing the front coil springs with 1 inch drop springs. If you cut the front springs to drop the front end 4 inches, proper alignment will be impossible.
rear leaf front coil springs
NoNo
How do I install rear coil springs on a 1996 Camaro?
I may be wrong but, the Wrangler has leaf springs on all 4 corners, no coils.
coil springs and independent suspension replaced leaf springs to give a better and smoother ride
Coil springs in the front, leaf springs in the rear.
