New Owner needs help...Thanks
 
Hey guys, I recently bought a 2006 TJ..2.4L Powertech 6speed manual with 3.73 gears...I'm interested in replacing the stock axles with same year Rubicon set up to do some mild off-roading and just strengthen it up to add some larger rims and tires..im not sure if this is the best route...i know its not the cheapest..but just curious what is the best without spending too much money...any advise on cheap upgrades to increase strength or overall improvement on drivetrain would be awesome..thanks

What size tire do you want to run? The front D30 can be made to handle 35's. I'd consider replacing the rear D35 with a Ford 8.8 if you want to run a locked 33" or larger tire. I personally wouldn't run antything over 33" with the 4cyl for street use.

can you weld? use the serach button or search google for "8.8 swap" and "HP D30", very common, relatively heavy duty, relatively inexpensive upgrades

if it is a 2.4 L it has 4.11 gears to beef it up a little i would do this
dana 35 rear super 35 http://www.sams4x4store.com/SuperiorDana35AxleKit.htm
and for the front dana 30 http://eastcoastgearsupply.com/i-159...shaft-kit.html
& regear to 4.56 & put you some 33 & you will be good also 2" BB lift & 1.25 BL

BB http://zoneoffroad.com/product?ki=20&gr=-1
to stay on the cheap side

my jeep came with the msrp sticker...it has 3.73's...and ya 32's or 33's is all i wanna go..and could i put on the rubicon locker system??or would that be too hard..and no...cant weld :(

thanks guys

it seems to have pretty good power even though its a 4 cylinder...the 6speed really helps it i think

i had a 94 with the 4cyl, 4.10s and stock on 33s and it was fine as long as you drive slow and wheel lightly. Now, locked is another story on the d35.

second jeep was a 99, 4cyl on 36s with 4.88s and hpd30 and 8.8. Both axles were locked (aussie up front and eaton e locker in the rear). I really like this setup but still slow on the hwy.

I think you should look for a set of 32-33s and go from there. If it is sluggish, regear. If you really want to wheel, look for an 8.8 to swap in. The do come with matching gears and you can find someone to help with the welding.

A rubicon rear axle would bolt in, be the same gear ratio as the front, and have the locker so that is a good bet too! I wouldn't worry so much about the d30...it will do well with 33s

My 04 jeep came with 4.56 gears, I thought all auto jeeps from that year come with those gears

There are better and bheaper options than the Rubi stuff, UNLESS you find a wrecked Rubi at the local junkyard. No you can not add Rubi lockers to your 30/35 combo as the Rubi has D44 front and rear. You can add other lockers like the ARB if you want air, OX if you want cable and then many options if you want an auto locker (the cheapest route). All 3 locker styles have their pros and cons, leaking lines, cable adjustment and unwanted locking and unlocking vs added on board air, you you can feel when it locks and cheapest respectlivy. I had a 4 cyl in my Jeep when I got it and had 31s on it, I thought it was fine till I added 33s and all the weight from armor. The 4:11s no longer kept me happy or the Jeep at highway speeds. Figure out your plans and budget. Plans include largest tire size, type of wheeling, needed and wanted armor and gear like winches. Do you want steel or aluminum armor? Low center of gravity or do you prefer the lifted Jeep look. Will it be mostly on road with minor off road. Does is still need to be easliy drivable for say the wife and kids? Once you figure all that out then we can help you a little better.
