Your going to tackle the regear process yourself?
If so, so am I but I'm trying to find the best tips and tricks to make it happen...
I've seen most of the tools and the basics but I know there's a lot of info missing compared to what I see on videos and DIY write-ups...

I am going to do the rear end because it is out on the shop floor easy to get to , dont know if I will try the front with it in the jeep . Here is a good video on doing the job .

winginit

I am still buying parts , and stacking them till I have enough to finish the job, then I will do it all at once . I bought some DYE diff covers on ebay just have to weld them up very heavy duty I had him add drain plugs for another 5.00 73.00 each

winginit

then I order my ring and pinon gears from rustys , and ordered a spacer so I dont have to run the crush sleeve on the 8 1/4 for 20.00 from Ratech #4114

And after much debate I pulled the trigger on a ATK 4.7 stroker engine , not that that their is anything wrong with the engine that is in their other then it has 176 thousand miles . 2,900.00 no core charge with shipping

winginit

I got it on the engine stand trying to get the engine assembled as much as I can before I pull the engine on the jeep , the engine is in good shape so I dont want to take it apart . So I picked up an oil pan, stud girdle, timing cover fel-pro pan gasket, timing cover gasket, and oil seal . It's a stroke so I bought some ARP washers 200-8557 to space the girdle, their .116 thick installed the washers and girdle, torqued to 35 ft pounds and checked with a feeler gauge and the rod hits on # 5 rod , guess I will take it apart and shim it some more , hope it clears the pan , we will see !!

winginit

I think I got screwed by ATK this engine is supposed to have a scat crank . That is not a scat crank , its a stock jeep crank with 4 counter weights , witch is 20 LBS lighter then the scat 9000 crank which has 6 counter weights . RRRRR !!!!!

You can't call and warranty the part?
I'd be truly heated to find that out...

winginit

I will give them a call tomorrow and see what they say .

winginit

I tryed another shim on the stud girdle , but that made it hit the pan in the front . So I chucked it in the drill press , using an end mill I machined a grove on the girdle to clear the rod I have .060 so I think it will be fine .

winginit

Update : called ATK , was sent to their warranty Dep talked to a guy named roger , he was a nice guy but know little about jeep engines, explained how stock jeep cast cranks have 4 counter weights and the scat crank would have 6 , he had no clue what I was talking about but was a nice guy, and asked me to send pictures .that's were I am at at this point .

Any updates?

I too am working on a retirement Cherokee.

I'm currently working on my 8.25 and adding Jeep Liberty rear disc. During my research I came across these "repair" bearings for the 8.25. It has two incorporated seals, inner and outer. The PR1559 changes the location of the bearing on the axle. As you know the steel used in the axle is softer than the bearing, if your bearing are worn so is your axle.

Thanks for all the information you provided.

winginit

Thanks for the reply , Nice find on the bearings I will keep it in mind .
I have been stuck in honey do list hell working on the house LOL .
Back on the jeep WOO HOO !!
