    Just wanting some insight on what problems can arise from running a different gear ratio in the front and rear axles.

    Anyone? /forums/images/graemlins/confused.gif

    It'll buck like a run away horse if the difference is too much.

    It will be very hard to get the hub's turned out.

    Stuff will Break if the gear's are too far out.

    theres two reasons to do this,

    1- if you want to run different size tires in the front and back

    2- if your a mud racer and you want the front tires to pull more/spin faster then the rear

    on hard ground/trails itll will mess stuff up real quick

    you can run 4.09's 4.10's 4.11's in your axles and nothing will happen but thats about it.

    massive drive train breakage. mainly the t-case.
    BUT, you select tires of a size that make the ratios the same in the final result you will be fine. for example...
    33 inch tires in the front with 4.56's gears turn 3018 rpm at 65.
    37 inch tires in the rear with 5.13 gears will turn 3028 rpm at the same speed.
    even on hard concrete this little diference would not make a difference. especialy if you get a true 33 inch tire and a 37 that measures 36.5 or 36 inches. yes the risk is there with this setup, but it is doable.

    this would look odd on a normal truck, but i have seen a 1950's ford body on a blazer frame running a similar setup only it was 37's in front and 42's in back. if it were not for the clasic hod rod look of the car that combo would not have worked.

    I knew it wasn't a good idea but didn't know the extent of the damage it could cause.
    Note to self: When swapping axles be sure to do both at the same time /forums/images/graemlins/thumb.gif
