    so i should be getting my d60 back and i was wondering how i go about breaking in the front gears. i know how to do the rear, but it seems like the front is a lil tricky. i cant run it in 4wd, cuz ive got a detroit in the 60, so steering would be rediculous. what can i do?

    I wouldn't really think you'd have to actually break them in, unless you have a FT4wd, it only gets used rarely anyways.

    Maybe 4 jackstands and rev up the idle while in 4wd??

    if your ballsey?:haha:

    All I did was went out on a few trail runs.... nice straight runs no real hills or mud... did that for a bit at low speed.. then picked up the pace.. then disengaged the front and drove around in 2wd.. then back in 4....... I guess i did it right cuz mine is holding up at this moment.. and I have been poppin the clutch in 4wd and in the mudholes...

    hard to tell but tell ya what.... lockers are sweet...
    sucky 160x100 vid... but like I said.. havent broke mine in... and they havent Broken in..... yet...

    lock the hubs and drive around, or at least on one side, just to get the gears turning, drive around for a while, thats what the dude who did my rear gears said to do

    4WD with hubs unlockes for a while. Switch from 4WD to 2WD once in a while to allow the gears to go through the heat cycles.

    If you just lock the hubs and drive in 2WD you will be breaking in the gears on the drive side of you LP60. It sounds good, but the LP or regular cut gears apply FWD power to the coast side to go FWD.

    In all I doubt that it really matters. That is just how I see it and how I do it....FWIW

    Was told to drive it for around half an hour to get the temp up in the diff. Then park it and let them cool.I changed out the gear oil afterwards too...:D

    Agreed. Wheel it easy for 20 mins, let it cool completely,wheel it easy for 20 mins, let it cool.Wheel a little harder in the same cycle, change the fluid.

    I have a 1996 camaro (not a truck I know) but now has 168,000 miles.. I bought it with 3 miles.. beat on it every day..... never drained the fluid... didnt break the gears in.. well I did cuz on the test drive I did a NICE burnout..... :haha:

    When I broke in my front gears, I put my t-case in front low and did about 10 front wheel drive burn outs up and down my street.
