I just messed up rear diff last night coming home from firework display. Sudden pop from rear while cruising around 50 felt like we hit a dog, following that clicking coming from rear. It is definatly something in rear diff... so instead of going back to the factory 3.73 I want to go to 4.56 what do I need to do and what am I looking at spending? Can I put 4.56 in front and rear axles just as it sits now? btw its a 2000 4.0 5 speed with 33's

front and rear will be okay to run 4.56. i found it to be like 800 bucks to regear front and back.. well thats what it cost my buddy
Thats cheap. Cost around here is around $1200-$1500. I would recommend a shop that specializes in that type of work.
Plan on lockers? great time to install them also, save some loot in the long run :)

Well for starters what rear axle do you have? I would think long and hard before spending money on the dana 35. Now if ya have the dana 44, then your set.

Did the same as you, got a regear for 975 parts and labor. So I decided to get chromoly shafts and an ARB installed at the same time. Most shops will charge you about 600-750 each axle. Atleast here in California. I shopped around for awhile and found a guy I could trust and does quality work. btw you will love 4.56. Huge difference especially offroad.

What axles are you running right now?

Not sure what axles they are the stock ones 2000 wrangler sahara 4.0 5 speed did they put different ones in different models how can I tell without opening diff cover what I have all I know is the metal tag has 373 front and rear... and by reading how much everyone likes the 456 gears with 33's as long as I been driving it with the 3.73 (which I thought was pretty peppy) it will prolly be like a supercharger feeling getting 4.56 no more downshifting to maintain speed uphill.

Do you have a plastic or metal fill plug on the diff cover? Do you have rear disk breaks?

the rear end it has now has the little metal tag on it also besides the one stating the gear ratio... hard to read but it can make out slip so is this limited slip? and what does that tell anyone else about what I have that is currently clicking and broken?

I'm not sure that your case is the same as mine was, but I had a similar loud "POP" come from my rear axle, followed by "click click click click" as I drove. It turned out I had snapped the cross pin that holds the spider gears in place... a new forged pin instaed of the stock one and I was back on the road with no problems.

ok... I now know we have a d44 in rear with limited slip and a 35 up front with 3.73's since not a hardcore offroader or crawler Im simply wanting to regear to 4.56...when doing this do I need to buy a new limited slip for the rear is this a locker. can someone please make me a list so I can calc up some $ figures such as gears, carrier (if needed), bearings...

Sorry for the lack of response. $1200 for parts and labbor give or take a few hundred dollars for regearing the front and rear axles. Be a good time to add a locker if you want one as well

so if i was gonna buy gears out right whats the difference in reverse cut straight and all that
Reverse cut is used in high pinion differentials to keep the pinion running on the strong side of the ring gear. Straight cut gears we don't run in axles but those are just straight 45 degree bevels on each gear, very noisy and not nearly as strong as the spiral gears you'll see in axles. Your Dana 30 and 44 are both standard gears, neither reverse or straight cut.

A good list of parts will b gear sets for front and rear axle, depending on miles you will need a minor or master install kit, and you gear oil. This is the right time to throw a locker n there whether it's a 1000$ arb or 250$ lockright, do a locker now.

Look on eBay and all over the Internet for your gear set. Most of the time you can find them much cheaper. I saw a set of motives for my 9" at 112 on eBay and 176.xx but 449.99 from jegs. Big name catalogs will jack up prices
