I don't do alot of wheeling and any is mainly just light playing in the mud or snow. i was jsut double checking if 33 allterrains would be fine to run on a stock dana 35 rear and dana 30 front i would still like to be able to drive at highway speeds and keep as much gas milage as possible you all tell me what is the easiest and most cost efffective way to achieve this. thanks

with 33s you'll need gears 4:10ish or so to keep it as a DD with half decent MPG. open open and not rock crawling you'll be fine on stock axles and 33s

its fine for me with stock gears and c 8.25 rear. gas mileage isnt that bad.

wouldn't guarantee that. I had an 89 Wrangler with stock 30/35 and running 33s, running down the hiway and spider detonated, wedged into the ring/pinion blew the driveline out. If you're going to do it regear is a must but I wouldn't recommend running more than a 31" tire without major upgrades to rear axel.

It'll be fine, some people have bad luck some people have good luck. I ran 35 mts on my dd and wheeler for years with the rear locked no prob at all

Im runnin 4:56 gears in my cherokee. I wheel it every other weekend and it is also my dd. Didnt notice too much of a mpg difference. I think that you will be fine. Gonna have to do some trimming though

chuckd2008

ok if i regear what ratio should i shoot for and what companys should i look into for parts? lastly does anyone knew where i can find any good write ups on this?

I ran 33x12.5 with 3.07 for over a year and it was fine. Sure it was sluggish but I had no complaint.

i run 33's on 3.07's i have little to no complaints. Instead of regearing i put my money into engine work and I have no complaints, Cruises down the highway just fine-5th gear even. Just on hills is where i have to drop into 3rd most of the time. Gas mileage sucks but its a small price to pay.

as far as axles go, there are very few cases were 33's on a DD will cause problems but it can happen.

i concur i run a 33x12.5 with the 3.07 dont really have much of a top gear but **** it goes ANY where. and i have a welded diff( wouldnt recomend for dd) but i daily the **** out of it lol

I don't know about write-up's, but tire to gear ratio is relatively common knowledge these days.
33's 4:11 will put you back at stock and 4:56 will give you a lil extra power. 35's 4:56 put you near stock and 4:88 gives a lil extra low end power. Any bigger than 35's and ur cherokee isn't gonna hold together all thagt well. Unless of course you chunk those factory axles.

There is a gear ratio chart on Randy's ring and pinion website.

and... there are tonz ans tonz of jeeps out there running 33's and 35's on stock axles. You can break a dana 60 if you try hard enough. If you play nice, you can run bigger tires on stock axles. Just know that you can overheat and burn up the rear D35 pretty easy. and... any re gearing to a D30 makes the pinion very small very fast. In a D30 it is more common to break R/P than axles.

On one of my trail jeeps I run 33's and full Detroit on stock 27 spline axles. Yup, I've broke 2, but at $15 a pop at the local junk yard, It's no bother to me.

i have 2 tj's on 33's, one with 3.07 and other with 3.73 both d35, there is a bit of difference, but no complaints.

my xj is on 36's on heavy beadlocks with stock 3.55 gears (d44 tho), but stock gearing and i still have no complaints.

i will regear the xj when i'm ready to spend money on my full size axles. i wouldn't spend any money to regear on my stock axles. it is VERY expensive.

if you must regear, you're better off searching for some 4cylinder axles from a scrapyard. they usually all had 4.10s.

if i had to guess, i would say the damage was done previously to the highway. like say, a piece of the spider broke off and on the highway managed to get lodged in the carrier causing complete failure. thats normally what happens.

DIY, its not to expensive

it is when you don't do it right.
the average person can't set the backlash or mesh the gears properly without proper tools and training.
