Regearing - Which parts to replace?

Hi Guys,
I want to regear my X to 3.73. Rear axle is D44, Front is D30.
Do I need to replace the Carriers?

no you dont need to change the carriers just to regear, they sell gears for your dana 30 and dana 44

are you doing it yourself? if not, just have the shop buy the stuff they need. or tell you what manufacturer they use. more than one person has had problems with gears. installer says it's a bad gear set, manufacturer says it was a bad install....

Does a person need special pullers to chage gears or do all the parts slide out after the axles or removed?

Sounds like your not sure what your doing, I wouldn't touch the gears. If not set-up precisely they will be permanently damaged.
And yes, special tools are required to properly setup the gears.

x2

I can work on motors and pretty handy around alot of things on a vehicle, but I will not touch gears. Need special tools, guages to check clearances, etc... They are not complex, but you must be very precise which makes it difficult to get right for a novice.

order your gears from Northridge. Tell them what you are doing. Most likely all you need to order is the gears and an install kit. You do not need to order a rebuild kit with the new gears.

Vendors..... If you want to sell me a product, Spend more time developing it than I did earning the money to pay for it. I'm tired of overpriced Crap!

Moderators.......let people call crap crap, that way it means more when people say something is Quality

3.73?

That is the lowest I have heard of anyone wanting to regear to... seems pretty low for the money that will be put into it. Just a thought, but you might want to consider something a bit taller if you are putting money into it.

08 Unlimited Rubicon.
04 Unlimited-sold
02 X-sold
98 Cherokee Classic, favorate vehicle I've ever owned-RIP

I'm thinking of a number between 2 and everything.

You mean that is a pretty high/tall gear for the money, and he should re-gear lower.

I know that most people put 4.88 and more.
But I beleive thatfor me 3.73 would be enough for crawling and good for highway.
(Northbridge has only 4.88 and numerically high).
So If anyone changed from 3.21 to 3.73 and higher, I would like to know if a carrier has to be replaced, or just the Ring & Pinion.

Thanks
