    I am in the process of doing this as well while at the same time putting a lift on.
    Do you recall tire size you can run with 3.55 and standard transmission that equals stock gearing? I can look it up, but thought you might know it.

    (New tire size/OE tire size) x OE ratio = New ratio

    33/29 = 1.1379
    1.1379 x 3.07 = 3.4934

    The larger tires will add some weight that stock gearing/tire size didn't have to deal with.

    Would a 96 Cherokee rear end fit my 88 or know if they gave the same gear ratio.

    So I bought a 1986 Cherokee Laredo 5spd 4x4 would the rear end and transfer case
    Work with my 1988 Cherokee 4.0?

    If the 86 is a 4.0 also the rear axle should work fine.
    The transfer case may, I am not as up on the tcase spline count and such as I should be. There were a couple of transfer cases offered early on infact the tcases we most commonly associate with the Jeep Cherokee (NP231 and NP242) weren't offered until 1987.

    The transfer case will work, however it is an NP207. Nothing wrong with it, but things like slip yoke eliminators and other upgrades are not available. Also spur cut reduction gears, so it will be noisy in low range. Also 2.62 instead of 2.72 low range ratio
