No it is not compatible as the electric configuration is different

88-98

Yes it is

2.5-3 Qrts(all depends on how long you have the cover off). Must use synthedic also!

if its a v-6 4x4 manual-2.73
automatic-2.73
if its a v-8 4x4 1/2 manual-3.73
1/2 automatic-3.73
3/4 manual-4.11
3/4 automatic 4.11

So go buy one at autozone for like 15 bucks

spider gears in rearend r broken and binding up on the ring gear

if i assume this is a 9 and 1/2 chrysler rearend...take the rear differential cover off..remove the screw tht holds the pin that passes through the spider gears then remove the pin. push the axle shafts inward til the c clips can be removed then slide the shafts out. you will need a bearing puller to remove the bearing and seal
