4.56 gears in a Dana 30 front
 

I have an "88" wrangler with a Dana 35 rear and Dana 30 front. I
currently have 3.55 gears in both diffs. and would like to put 4.56
gears in both.
The literature I can find says that if I have 3.55 or lower gears in
the D35, I will be ok. But what I need to know is if the 4.56 gears
will fit in the D30 case? From what I can find it sounds like I'm
going to need a housing with 3.73 or lower gears in it for the 4.56 to
fit.I need to find out the real answer.
Has anyone out there put 4.56 gears in these size housings?
Any help or advice would be great.
Tom

Yes. I upgraded the stock 3.07 gearing to 4.56 in the D30 front and ran
with that configuration for several years before replacing the entire
front-end on my 92YJ. 4.56s will fit the D30.

Hi Tom,
The Dana 30 will need a carrier change:
http://www.----------.com/tooth_count.txt Now is the time to invest rear
axle upgrade, because the 35's pinion will be too small for even stock
tires: http://www.off-road.com/jeep/tech/Axle.html Or take a camera with
you so you may add to my site at: http://www.----------.com/dana35c/
