also, you should never ever change the ratio in a Dana 35. that axle isn't worth the investment.

 

change gears by changing axles. :thumbsup:

I would love to up my axle to a dana 44 but i don't have that type of cash and a guy at audo zone told me since i got biger tires then i need to. and i have a 2wd :( with a dana 35 idk what type of tranny i got. its all stock

it's simpler than that. Over the years Jeep routinely put the same ratios behind certain engine/trans combos.

 

4.0L or 2.5L?

 

auto or manual trans?

 

if manual, 4speed or 5speed?

 

You don't need to get a 44, another 35 with a better ratio will work just as well. It costs way more to change the gear ratio in an axle ($300-500) than it does to buy a junkyard axle with the ratio already in it ($100-200).

rly i thought it didnt take to much to change your ratio. and its a 4.0 auto

then you should have 3.55s now. :thumbsup:

 

I'd look for a 4.10 MJ or XJ rear axle. car-part.com may help out. be sure to check the various generations of XJ since minor changes in the rear axle can change the part number and thus change the search even though the axles will all work for you purpose. an 8.25 or Dana 44 would be better than a Dana 35 if you can find one with 4.10s. :thumbsup:

 

 

gear changing is not as simple as unbolting this and bolting in that. gears must be set up perfectly or they will make noise, wear out quickly or in a worst case scenario, die even faster than that. changing them requires some specialized tools and a lot of experience. and even a pro could spend hours on a single axle. It's one of the few things I leave to a pro.

:D

that's what we're here for. :thumbsup:

[AMC-MJ]

:fs1: Hey now :wall: The MJ AMC-20 is a fine axle too and already has 4.10s . . . 4.10's would be the ideal all around gear.

 

I let some body else do gear swap's on axles i don't know, and on axles i know well i let the experts do it especially if its a valuable machine or a non replaceable axle . . .
