I'm looking for info on a possible axle swap on my '48 Willys. The finial
goal is to upgrade brakes and lower the gear ratio (now a 5:38) at the
same time and save money doing it. I would like to get it to cruse around
60mph. I only do moderate off-roading so I don't really need this taller
gear.. Any ideas?? Thanks

Have you looked into an Overdrive set up? This seems like the cheapest way to go. If you changed ratio's you would have to do both fronts and rears and the dollars would add up. I run an old Rancho overdrive in my CJ-2 with 32" tires and with the 5.38:1 gears could cruise at 60 mph. Advance Adapters sells the old Warn overdrive that bolts right into your transfer case with no driveline mods. That way you could keep the good gears for the off road stuff and still be able to hit the freeway.
As for upgrading the brakes, theres a 10" brake swap that works well. I think 4 wheel parts wholesalers sells it. Dana 30 or 44 front disc brakes are also a bolt in with just a little grinding on the knuckle.

Thanks for the reply. That's kinda what I needed to know. I've found the
warn o/d but there kinda pricey,$1000. Never heard of the Rancho o/d unit
though. I'm running 31X10.50 now and have a set of 32's in the shed but
wasn't sure if the stock axles would handle them or how much that would
help me.. Where did you find the Rancho O/D unit? Any idea where I can get
some info on it? Thanks again.

saturn od might be pricey, but add up the cost of new gears, seals, and labor and you come out about even.

The Rancho OD unit bolts on at the rear output of the transfer case and requires the rear driveline to be shortened. It has an electrical solinoid that allows down shifts out of overdrive for passing et. It has been out of production for years. Mine was on the Jeep when I bought it. If you look around you might find a unit, but then again replacement parts are hard to come by.
The old Warn (Atlas) unit is the best bet and price wise would be a wash with a gear change or replaceing both axles.
