When replacing springs, it is necessary to replace the coil spring isolators? I have purchased a new set of upcountry springs for my WJ and am on the fence about replacing the isolators. Has anyone replaced their springs with the old isolators?
I reused mine but only had 50k on them. Like cheap said if you don't have obvious damage probably ok. You may get a bit of a lift out of them by swapping them out with new ones due to wear and age.
I ended up ordering the coil spring isolators. I figured that it would be better than taking it apart and needing them. I am going to measure the height of the Jeep before and after to see how much It was sagging. I will measure from the ground to the fender and center of the wheel to fender.
Glad I went with new isolators, the factory isolators had just about collapsed all around.
Before - crushed isolators, standard sagging springs
Ground to fender front
31.5"
Ground to fender rear
31"
Fender to center of wheel front
18"
Fender to center of wheel rear
17.5
After - new isolators, upcountry springs and airride air springs in the rear
Ground to fender front
33"
Ground to fender rear
33"
Fender to center of wheel front
19.5"
Fender to center of wheel rear
20"
I replaced them when I put my lift on. I figured it was a good thing to do while I had it apart. They weren't all that bad to tell you the truth but I did it anyway. I got them all from Rock Auto for about $120 shipped.
