QT Chain Replacement - Advice?

I am venturing into uncharted territory and have been reading the TSM and multiple web sites about the QT. I have a few questions for you QT gurus.

This is a 77 Cherokee, 100k miles, 401. It appears the case has been apart (sloppy reseal) but the chain has so much slop I drive it very gingerly if at all. There is an occasional pop or binding sound when backing or turning but not often. The E-drive and low range work well and there are no leaks. It's a real nice Cherokee overall and seems to have been well cared for.

But I know I need a chain.

1 - can this be done with the case on the vehicle?
2 - what else should be routinely replaced?
3 - are there step by step instructions for chain replacement?
(I haven't found any yet)
4 - what is the purpose of the overdrive chain?

If any of you have been through this and have pointers or cautions, please let me know. Thanks!

There are instructions on this site on how to do it on the vehicle. I just did one by dropping the transfer case. Not that much extra work.

Yeah, several How-Tos. It's a 3 hour job if you have never done it. 1.5-2 hours the second time.

1) Absolutely. it is MUCH easier to do in the truck.
2) If you are still full time, you may want to disassemble your pack and inspect. but that's about it. Maybe the replace the soft lines that connect to the hard lines to the vacuum motor? Obviously the fluid...
3) Yeah, they are in the service manual. You can also use the Mile Marker Part time Kit instructions. A couple members on here have good write ups, too.
4) You don't care unless you have a part time kit. There were some part time kits with overdrive sprockets and the chain is slightly longer. Get a stock chain if you still have a stock case.
