A Little update 

have some play in the steering rack 

can This be the Problem ?

I don't think that's your issue.  If the problem is with a worn steering rack, you will get vibration or clunking noise from turning, and regardless whether torque is sent to the front or not as you described.  If you didn't have someone else grabbing the steering wheel as you shook the tie rod like in the video, there would always be a bit of play.  Or could be that your steering rack bushing is very worn, either way that should not be the cause based on what you initially described.

Like others mentioned, it could be the plates in your transfer case.  A small bottle of friction modifier costs $10, and it only needs an ounce of this stuff per quart, it's a cheap way to find out if the issue is with the plates in your transfer case or front diff.

Ok Thank you !

can you recommend a friction modifier?

I used Redline before, but it's common fluid and if you Google you can find a dozen different brands out there, so just get whatever is available local to you.

Hello ,

 

A Little Update ..

I added the red line oil to the transfer case and still have the same problem.  I checked the front differential and can't really find anything there either... I looked in with an endoscope and will show you the pictures!

sorry for the bad Quality ..

Don't know if there's anything to see. Seeing as those photos will be on a memory card.....why not upload them direct to the thread?

Yeah I couldn't tell if anything was off based on that.  Like others said, now it seems like it could be the transfer case on its way out.  On a R32 the AWD fuse can be pulled to test, is there a way to disable AWD on a R33 to test?
