the guys in my off road club are starting to make me wonder if i'm getting in over my head:
"Takes alot of the right tools and alot of experience and sometimes a great deal of time to set up gears. They sadly don't just "bolt in" like a complete axle would. There are some pretty tight tolerances that have to be shimmed properly and loaded properly to make the gears last."
"You will have more money into a re-gear than a used axle swap. You will need a master install kit and they run about $150-180 for a quality TIMKEN set with all the bearings, spacers and shims. And then you have to worry about carrier breaks for some axles (meaning a different carrier is needed depending on the ratio).
Another good point for buying a decent used axle assembly: If its the same or similar to one you are replacing-you now have spare parts...axle shafts, brake components ect...
The only way I would do a complete rebuilt/regear is if i were adding a locker."
...i just want my 4wd to work again

*sigh* so sometimes i wish life could just be less complicated...have to put about $170 into tires and alignment on the honda. down to the wear bars in back and feelin it slide on dry roads now and that's in addition to the exhaust pipe, which i really probably ought to fix
found someone local who has a 3.55 pumpkin assembly...says make an offer, he'll let go cheap...

the front you definatly need the bolt in replacement, as much as i could move that gear i wouldnt trust the case, the rear axle you could go either way, if you can get an axle it would be easier

tell me about it...
the guy with the front has the whole pumpkin...he switched to 4.10s too...
so now i'm kinda stuck. hmm. keeping the 3.55s would be cheaper, thus leaving more $$ for 6637 and then stacks...

Consider 35" tires with an E4OD and 3.55 gears, 3300 RPM would be 135.2 MPH in overdrive.
Now 4.10 gears with the same everything else, 3300 RPM would still be 118 MPH.
Looking at the low gear speed, 4.10 would run 30.9 MPH at 3300 RPM.
The 3.55's in low gear will run 35.7 MPH at 3300 RPM.
60 MPH in overdrive 1450 RPM with 3.55's.
60 MPH in overdive 1680 RPM with 4.10's.
Be careful with drop hitches towing.
The max tow weight can drop off fast with big drops.
Where is Pungo?

lmao!!...and i've heard to be careful with drop hitches, which is why i don't want to go too much bigger on tires. i have a good hitch that came with my trailer- fits my weight dist bars...but i already have to get someone to stand on my bumper to unhitch
pungo: as far south and east in the city of virginia beach as it is possible to go without getting in either north carolina or back bay

You'll gain lots more acceleration. For towing I have a 10" drop receiver hitch class 4 and use an aluminum 8" dropped ball hitch. The aluminum ball hitch is rated at 14000 lbs where as the steel ones rated at 10000 lbs. I know where Pungo is been there many times when I was stationed at Littlecreek and Norfolk for almost 9 years

Actually given the RPM you are turning at 60 MPH with 3.55 gears, the 4.10 may do as good or better.
More time in OD and less downshifting.
1950 RPM at 70 MPH with 4.10's and 35" tires.
That would still be decent MPG with my IDI, the Stroke should be about the same.
I don't know exactly where you are, but close enough for government work.
I helped build a water treatment plant on J Clyde Morris Blvd just outside Hampton Roads. I spent a good while in the area 20 years ago.
