Howdy all. Registered here so I can pick some brains on occasion.
My wife's car is a '99 Grand Vitara. Four wheel drive, automatic with the 2500 engine. Got 200,000 miles on it. Still quite a nice car but it's at the point I gotta fix things.
The woman neglected to tell me that her car started getting a vibration and grinding sound at 55 mph. Said she didn't notice it. Took the car on a short trip this past weekend and the vibration/grinding issue was down at the 45 mph. range by the time we got home.
Just went through this two weeks ago and had to replace the u-joints in the rear shaft on my Tracker, so I grabbed some new joints and put 'em in. The old joints were worn but nothing 'loose'. Replaced 'em anyway.
That cured another issue I didn't know that we had but not the grind/vibe issue.
Put the car in the air, checked for wheel play, noise, anything odd and found nothing at the wheels.
Checked the front halfshafts and found that the inner bearing of the right shaft is pretty loose and I could rock it back and forth with my hand, so OK, I know I'm replacing that halfshaft.
The grind/vibe has occurred in normal two wheel driving (and in a test drive I notice slipping between 2 and 4 wheel has no effect on the vibe) and I'm thinking that in 2 wheel that shaft shouldn't be moving. (My 4 wheel Ranger with auto hubs doesn't.)
Do the Vitara halfshafts stay live at the wheel in 2 wheel drive?
In a way that would be nice from a repair standpoint regarding the vibe, but I'm thinking I still haven't found the source of that problem.
Oops, sorry about my description. It's the inner CV joint that's loose.
Thanks for the answer about the halfshaft staying live. I assumed it did just by the looks of the situation and the fact that it's live right now when I spin the wheel. The set-up doesn't look like any auto hub that I'm familiar with but I've made the wrong call before.
That also makes me feel a little hopeful that replacing the halfshafts kills my problem.
If you are concerned about the front shafts being "live", you can install manual locking hubs. I feel there is no need for them personally, as the system IS designed to have the shafts always rotate, without issue.

If the right inner CV joint is loose, it's pointing to a problem in the differential, most likely with the side gear - there is no support bearing there and this has been known to cause problems from time to time.
