The jeep has a lifting and dropping issue when I stop then start.
Is this from dead leaf springs?
I tried to search but did you ever include the word "lift" in search on a jeep forum
The truck has 4wd and the leafs have 200k on them so I am changing them anyway, just making sure if I do change them this leaves with them.
Ideas welcome.

Hahaha that's pretty funny! Ya you're going in the right direction. Shocks will be a factor!

It could be that the slip yoke is in desperate need of lubricating. The later XJs used a moly grease or some such on the slip yoke while the earlier ones were lubed with ATF from the trans.

The front slip was greased by me last week.

Ok, I have shocks on the way.
It is hard to describe what it does. Hope it is just shocks.
It has 200k so I am sure new leafs are in order.(soon to be done)

Rear Driveshaft - The rear is a one-piece shaft with standard u-joints at both ends. The slip yoke is located on the output shaft of the transfer case. On 84-95 models, the yoke slides in and out of the transfer case and is lubricated by the ATF fluid internally. On 96-01 due to a design change, the slip yoke is external (does not slide in and out of the transfer case). This slip yoke is covered with a rubber boot.


The above is from another site. '96 and later have an external slip yoke in the rear and the splines need to be lubricated.

Thanks for the info!!!!
I will read up more about it tonight.
Would you know whats involved with doing it?

You have to cut the metal band around the rear of the rubber boot, pull the driveshaft, clean and relube the splines, and reassemble.
