So how important are spring isolators?

Was just putting a teraflex leveling kit on my 13 JKU and noticed the rear passenger side spring had no isolator. I have 13k miles on the jeep and only noticed it was missing just now. I put in the teraflex leveling spacer in the back, which will serve as an isolator I suppose. So, other than the back end of my Jeep not sitting perfectly level, will there be any ill effects of not replacing the missing isolator? I really do not feel like dropping that axle again, and I doubt Jeep will replace it since I put in a leveling kit.

Isolators can keep you from destroying your spacers, the front is more of a problem than the back though. I would talk to the dealership and see if they will give you a set.

Well SOMEONE has to ask it: Are you sure the isolator wasn't just stuck to the jeep when the spring came out?

Yes, we looked thoroughly for it. It was just not there.

If it's not there I'm surprised you did not get a lot of noise from the spring rubbing on the frame spring pocket.

Well it wouldn't be unheard of in the jeep world...my 06 didn't have rear isolators from the factory. There was no noise generated without them. Springs have a tendency to stay put under all of that weight.
