Never set gears before??

I have an 83 CJ7 with 2.73 gears. When I put the lift and 33" tires I basically lost 5th gear(t5) and need a tail wind to break 55mph. I found a set of narrow track axles on KSL with 4.10 gears. The guy wants $150 for the axles and as far as axles go, they look OK.

Question #1 Am I right to assume that I can take the gears and carriers out of those axles and put them on my wide track axles? (both are dana 30 and model 20 axles)

Question #2 Is this something I can do myself, having never done anything like this before? I am pretty handy, did my own lift, and YJ spring conversion, but I am not sure if this is too far above my pay grade.

Thanks for your direction!

Yes they can be swapped in, but they will have to be set up just like new gears. Its not impossible to do yourself, but it does require some special tools. Be sure to do plenty of research before you begin.

If you decide you don't want to tackle it yourself, you can save a lot of labor cost by dissembling the axles yourself & removing them from the Jeep. Thats what I did and labor was just about $300 for the gears installed in both axles, bearings pressed on the rear shafts, and ball joints pressed in knuckles. I still want to learn to set up gears, but didn't really have to time.

You need special tools(dial indicator that reads .001", a FT/LB torque wrench and bearing puller, etc)and the knowledge on how to use them.
It would be best for you to watch a pro do it and take notes/pictures for the future.
R&P set-up is about the most critical operation on any vehicle.

Most of all, you need to know exactly what you're doing and a ton of patience.

I think patience is more important than knowing exactly what you're doing. There are plenty of tutorials and step-by-step instructions available online. The "special tools" are readily available, and not prohibitively expensive. I did mine after a bunch of research and studying of online write-ups. Once I got started, it took the better part of two weekends to get both axles done. I did end up taking my carrier and pinion gears to a local shop to have the old bearings pressed off, totally worth the $20 he charged me.

As long as you have another vehicle to drive while your Jeep is immobile, I'd encourage you to tackle this one yourself.

I recently decided to have someone else change mine for me. If I had a garage instead of a spot in the mud and sleet I might have tried it myself.

You need to know how to read a 'pattern'.
That comes from 'hands-on' learn'n under a pro.

Unfortunately - I understand this all too well.

From some initial research, it looks like I will be taking this to a pro shop. I have a driveway and need the CJ as my DD.

What else to I need to buy when I take this to a shop? Just the gears?

most shops will want to order the parts. if you bring the wrong set or something they do not want to warranty. Plus they need a master install kit.

Don't be afraid to talk to them about what you are looking for ahead of time. If they don't want to discuss it... go somewhere else.
