Thread: T-case issues

  1. #1

    Default T-case issues

    Ok today's that kind of day that anything that is wrong with anything, it seems to be my stuff. A while ago, I had my rear end on jackstands and installed a pair of 1/2 spacers for the rear wheels and decided to put it in drive to see if I have the parking brake issue still. Well a new issue came up, this time in the transfer case.

    Its a New Process Gear 246GM; 272 gear ratio and it makes kind of a slapping metal to metal noise. It does it mostly in drive and is barely heard in reverse. The u-joints are new and the boot is not torn that I can see.

    Are these transfer cases gear driven or chain driven?

    *Oh its push button and as far as I know, Service 4WD is not on in the DIC

    If at first you don't succeed, chances are, you are using too small of a cheater bar

    is it a constant noise or just occasional? My truck makes the same kinda noise at times. I think that it is the bushing for the slip yoke in the tail shaft of the transfercase. If i push up on it I can duplicate the noise

    Its a constant noise. Did listen to some youtube vids and the noise doesn't sound like the chain slap but who knows.

    This is the video I am talking about. In the beginning you can hear the noise its making. This one turned out to be bearings. @Pikey

    Thanks Alox. I'm almost at my wits end with this truck but eveything in my body says keep her. Might just buy a used t-case for $350 and have a family memeber who is an expert in gears and whatnot do a partial rebuild of the used one. Alot of electrical and mechanical needs to be fixed.

    How much do you guys think a partial rebuild would cost?
