Gear change to 4.56

Axle, axle, axle..... WHAT AXLE? Some axles require a new carrier, some don't.
 
nope, it just drops right in.

You probably don't even need to replace the bearings or anything. ust bolt the new ring gear to the carrier.
 
hey not to hi-jack but do you need a new carrier going from 3.55s to 4.88s? I upgraded from 3.55s to 4.56s and can't remember if I was able to use the stock carrier but want to upgrade to from my current 4.56s to 4.88s.
 
Did the very swap a month ago ... As stated, going from 3.55 to 4.56 will require a new 3.73+ carrier for the D30. No carrier is needed for the C8.25.
 
Tip: ZJ's with v8s have 3.73s, junkyard carriers are like $15-20. Yes, a low pinion and high pinion share carriers
