changed my bags for springs and couple questions

[07_Envoy]

ok so i was finaly sick of my leaky air bags. and it was time to upgrade / repair the 8.0 rear end to the 8.6. so i had the springs and put them in as well since the axle was out. now my only question is there suppose to be a isolator that is suppose to go between the top mount and the spring and the bottom of the spring and the rear diff? because i just took the old bag out and put the springs in and now it almost sounds like there is a little coil bind our twist of the springs when being compressed a little bit.
thanks

There is supposed to be a isolator on the top.

Thanks I just ordered from my dealer. I thought there was one for bottom too but guess not

No, just top only. Here's a pic:

pics are worth a thousand words! To me it just seems like there should be more attached to it but I guess that's all there is.

It's for noise reduction only as far as I know, and if I needed to add some I'd just use sheet neoprene or a cut-up truck inner tube.
