New IX jack test failed

[e30s50dan]

While both TC were on the ground side by side,I slid in the front drive shaft in the old one,and held the rear drive shaft output,ZERO resistance.... the one I got from a fellow r3v'er,has a lot of resistance (VC good)

In fact,the old one was so bad,I can stick my fingers in front DS spline,and turn it and feel no resistance

What? A worn VC will give you ZERO power to the front wheels. I did a one-wheel peel up my driveway a couple winters ago and that's how I knew both the xfer case and rear diff had bad VCs.

if you lifted a front wheel, you can be certain your transfer case vc is good but you will have no way of knowing if the rear diff is good.

no. the front and rear are mechanically connected through the planetary gear set. the VC controls slip, torque isn't directly transferred through it.

it doesn't send all power to the rear either! the only reason that happens on a slippery surface is the torque output is already biased towards the rear (via the planetary gear). On a surface with equal traction to all 4 wheels, all wheels get torque regardless of if the VC is working or not. In fact, you could remove the VC entirely and it would still drive all 4 wheels - but it would be an open differential.

No. A worn VC will send all power to the axle with no traction. There's a subtle, but important difference.

A worn VC is not the end of the world. It is still four-wheel drive, just not as capable as it could be. The best I've heard it described is that now the transfer case acts like an open-differential instead of as a limited-slip as originally intended which is consistent with what you describe. Good luck.

Off topic question .. Any of you ix guys happen to have an extra drivers side skirt ?

[audiquattrot]

make sure you replace the shifter bushings while the TC is out. You can't access it without dropping the TC.

this was my biggest mistake. Shifter slop all over the place, and had the chance to change it all during the 5-spd swap.

I have another TC. Just waiting on parts. Thanks

The VC can be had for $580 and probably a long wait for it to come over on a boat. Plus labor to install. Good luck.

Here is one example:

I've been searching. Looks like TC priced between $1600-$2000

Looking for just theVC

It's a manual

Is.it a auto.ix or stick. I have a tc laying around
