HELP!! I need your Axel opion and advice!!!!

This week I had planned to swap the axels out of a spare CJ 7 into my CJ 7. Right now, I have the 258, T5 transmission, Dana 300 transfer case, with 4:10 gears. This give me a crawl ratio of about 43 and a highway RPM of around 2000. My plan is to install an AMC 360 with the T18 and Dana 300 transfer case. With out the over drive the 4:10 gears would give me a highway RPM around 2670 that is high but it would give me an awesome crawl ratio of 66. My plan was to switch axels that have 3.54 gears and not to mention better hubs. This combination would give me highway RPM of 2300 and a crawl ratio of 57. After to pulling the axels out of both Jeeps I realized that I had the wide track axels and I was trying to swap in narrow axels. I want to know everyone’s option because I don’t know what to do now. If I went ahead with the swap of the 3:54 would the narrow axels cause my 33 12.5’s to rub or lesson my turning radius. Is anyone running the narrow axels with 10-inch wheels and 4 inch back spacing with the 33-inch tires? Your input is greatly needed. Thank you.

Keep the 4.10s. 3.54s are marginal to run with 33s or bigger. Also the stability of the widetracks is important.

But don't forget you'll have a wee bit of a hard time getting that thing up and moving with that high of a gear and those big of tires.

Forget about the crawl ratio. The width is the important part and swapping to the stronger 6 bolt hubs is a half day job. Stick with what you have.

and the narrow track axles just look gay under a lifted jeep... wiiiider is in deed better.. stick with them.. and dont worry about the gearing so much.. and rpms.. im running a t18 with 4:10's.. and 35" tires.. i cruise at 75 all day.. the engine isnt too fond of me afterwards.. but hey..

I don't know about your axle problem, but I would not run 10 inch wheels on 33's. That amount of backspacing will change your scrub radius enough to cause severe death wobble. I had that setup on mine for a while, after I dropped back to 8 inch wheels my death wobble disappeared. For axles wider may be better, but for wheels, narrower is better. Not to mention they will hold a bead better.
