Rear Spring Isolaters

Since I put my Frankenlift in, I am realizing the rear needs a little lift to level it out better and give a slight rake. So, I've ordered 2 MOPAR upper rear spring isolaters to give the rear a boost. I've read some posts that say the JBA's are too stiff, and problems with it slipping through the spring?? What's the easiest way to get these in once they arrive?
I want to get this KJ truly trail ready! :roll:

Confused

Not sure what you mean by "them" slipping through the spring? Don't see anyway that the upper isolators can slip through the spring, they are bigger than the spring the spring holds them up in plus the center which slides up over the bumpstop.

Where did you read this at?
Heck I ran two lower ones for several thousand miles and they never slipped out

So, I just have to disconnect the sway bar, pull off one side of the shock and the spring should be able to be pulled out w/o compressors with jacking the proper spots?
I think I want to add a thicker bumpstop as well while I'm back there.
sorry for my newbness.

Don't have to disconnect the sway bar really
jack it up remove tires, put on jackstands
Remove shock, or just the top is all that is needed,
let the diff down
remove the bumpstop if you have any
remove the spring
install the isolators
now you will either need for someone to push down on one side of the diff OR
use the stock jack between the frame and the caliper, spread it apart install spring
reinstall bumpstops
bolt up the top of the shock
Go to the other side do the same
tires back on off the jack stands
and now
SMILE as you stand back and look at your handy work.

Or you can do it like I did all by myself (no helper, no jack) and darn near drop a nut (testicle, not fastener) trying to push down the axle with one hand and shove the spring in with the other. LOL.
