    Sound like you must have broken a gear,or some gear teeth maybe.There is no chain in that case,gears only.

    Does it do it in 2WD ? 4WD ? or both ?

    The play is in which driveshaft ? front or rear ? In 2WD or 4WD ?

    Sorry for all the questions,just trying to get an idea of what's going on.

    BTW - Welcome to Plowsite :waving:

    Thanks wyldman... lets see, rear output shaft (rear driveshaft), its bad in 2hi, a little quieter in 4hi, barely noticeable in 4lo...I guess the thing to do is remove some sort of view plate and give that rascal a visual before removing the unit. I'm not thrilled with the prospect of a costly repair only to have some other integral part fail...do you think replacing the whole unit(transfer case)is the way to go? I plan on keeping this beast in service for a couple more years...a Jasper th400 was installed in apr 03.

    It sounds like something is broken inside.Disassembly is the only way to find out.

    If you don't feel like tearing into it,just get a used unit and replace it.Probably cheap than rebuilding it.I wouldn't be afraid of a used one as not much ever goes wrong with them.They are usually pretty bulletproof.
