Chrysler 8.25 with 4.56 Yukons install

[87xjco]

Chris (Sting25) has a 1998 XJ with lot's of lift, 33" tires and 3.07 gears, he brought it to me to install 4.56 gears in his rear Chrysler 8 1/4 and the front HP30



Chris purchased Yukon gears and master kits, the 8 1/4 does not require a new carrier, but the pinion cross shaft will need to be ground in order to clear the ring gear on re-install

First I remove the retaining bolt and slide out the cross shaft


Then the axles can be pushed in and the C clips removed


I'll use a center punch to mark the left cap with one mark and the right cap with 2. then i'll remove the carrier cap bolts, this also frees the side carrier adjuster nuts that are used to adjust carrier bearing position and preload

I will then knock out the races, there are two spots in the casting that allow a punch to contact more of the race surface when driving them out


I'll install new races by using the old races, a long round punch and hammer as drivers, and tapping them in until they are seated in the housng
