Went from 4.10's to 4.56....for free
I snagged a 4.56 D30 from the yard for $100 a while back, and put it in myself on Saturday morning. Sold the 4.10 D30 I took out for $125...net gain of $25. Jerry (another MJ guy) and I swapped rear axles yesterday (he had a 4.56 D35 and wanted my 4.10 D35) so that was no cost either....
All I gotta say is ANY 2.5 should have come from the factory with 4.56's. I can't believe how much more responsive it is now!
I also installed new leafpacks in the rear and got about 2.5" of lift....will be lifting the front with some ZJ springs this weekend to level it out.
Started with the D30 on Saturday morning….had it swapped out in about 3 hours working by myself.
Step 1, pull old D30:
“new” axle, cleaned and painted:
my shimmed CAD motor:
also swapped the stock tie rod with a ZJ one, notice the beef:
using a bottle jack to remove/install coil springs without unbolting everything:
all done:
