    ........i popeed it into drive and it went boom, and then didn't move, so i called triple a, i was only within like 2 minutes walking distance from my house anyways. i pulled the diff cover and parts started to fall out, well that can't be good. luckily i was after i went to the trail and not while in the woods, so now i'm in search of a 14FF with 3.73 gears so when i run my 33's and so they'll match the ones up front, will it be ok to run 3.73 with 35's????????

    BOOM.
    My rear end does that all the time. Then the little woman tells me to get out of the house.

    There is another guy looking for 14FF 3.73s at the moment. I have a whole diff in Ca.

    I've got a 3.73 ring and pinion for a 14-bolt. Cheap! If ya need 'em... But for 35's I run 4.10's or 4.56's.

    Re: rear end went boom

    That would make it handle really strange. The front end would be trying to go faster than the rear end. [​IMG]

    Re: rear end went boom

    then your t-case might go boom to match the rear end...minute differences (4.09 4.11) are fine. when it gets into tenths it gets bad...or so i am told...

    4.10's would make it easier to light 'em up. 3.73's would make 'em spin faster for a given engine speed. [​IMG]

    Re: rear end went boom

    I would just go ahead and get a 4.10 or 4.56 (if you have O/D). You might think about running 33's in front and 35's in the rear and only using 4wd if you get stuck. You would be less likely to mess up the xfer that way (it might look cool too[​IMG]).

    Re: rear end went boom

    or you could do it right, same size tire and same ratio. 35's i would not go smaller than 4.10. i would personaly recomend 4.10 if you have a stick. for an auto i would go with 4.56.

    Re: rear end went boom

    the only reason that i need 4wd for now is the winter(i live in new england), i think that i'm gonna get the 4.56 rear end because i've alreardy located one, it's for 250 bucks.is that a good price, it's also out of a c30 so would that still be OK?? then mabey in the spring i'll get a dana 60 if i can afford it
