If you are looking to go with 4.10s just do what I did. I found a dana 30 from a 4 cyl. tj that came factory with 4.10s. I picked it up for $300 and I should be able to get $150 out of my 3.07 gear dana 30.
all in all I will only have $150 into my dana 30 gear swap

 

I agree. Anyway, 4.10 gears wont fit inside a 3.07 differential.

Harbor Freight has a 20 ton press on sale this week for less than $200

 

Just so we are clear I paid $300 for the entire axle assembly not just the carrier and gears.

 

I paid $150 for a D35 4.10 and $100 for a D30 4.10 axles brakes and all from CL. I then posted my 2 3.07 axles for $300/pair, a guy came by needed only one but bought both for posted price. The next day he sold the other one for $200. God Bless America! :dance:

 

Thanks for the information, but I want to do the gear install. This is not about money it is about learning something new. Even if it costs me more in the long run I am okay with that. I just want to learn and have fun working on my Jeep. So any websites or books to help me out would be appreciated.

I'm in the same boat!
I've been reading Randy's book from Randy's Ring & Pinion. I have been recommended his web site many times. There is a grip of info there and in his book. I think he's like the ultimate authority in gears or something.

Here's his link. Randy's Ring & Pinion. The Differential Experts. Auto Parts & Services.

" gear install jeep"

there is a really good write-up on a popular forum. He did a very good job, made it seem easy although doing you own gearing is not recommended-even by the more experienced techs. I would try it If my jeep was not my DD. Good luck

Mine is my daily driver, but I usually ride the motorcycle to work when it is nice out. Yep I understand you need to regear both the front and back. I picked up a whole rear axle with an ARB in it last week that is geared to 4.10. I run 3.73 right now with 31s, but 33s are in my near future. I have the auto tranny.

Very good write up for installing gears.

Hey, Doc:

I, too want to regear my Dana 30. I am actively working on replacing my D35 with a Ford 8.8 that is already geared to 4.10. Bill Ansell's article "Gettin the Gears Done" at pirate 4x4 is a must read. The bear its getting all the proper tools. The job simply cannot be done without them and some are prohibitively expensive. Fortunately I have a friend who used to do gearing and is letting me borrow the tools. As far as a press goes you can probably take your new pinion to a machine shop and have them press the bearings on for you. When I do mine I'm going to drop the axle to make it easier to work on.

I have been searching multiple states on craigs list for a 4.10 geared axle so far no luck. Daveys jeeps in ohio wants over 600 dollars. And I worry a donor axle maybe damaged from a collision; I know mine is in good shape.

It will likely be next year before my ford axle is ready and I can afford the swap but I look forward to your progress in regearing.

 

If I wanted to do a regear I would not mess with the Low pinion D30. I would go find a HP D30 from a XJ and regear it. You will be using reverse cut gears but everything else will bolt on. Try and find a non disco unit and it is a direct bolt in. I found a 99 for 150.

 

x2. such a better way to spend your money. what rear axle are u running? please dont say a stock d35c with the ARB...

 

After reading the book I am going to pickup a HPD30. I already found a few locally.

 

Yes I have the stock D35 with a ARB locker and chrome-moly axles on the way. I do some pretty hard wheeling, but will never go above 33s. I have done quite a bit of research and everyone I have spoken with said this will be fine including Jerry.
