In motion? Or sitting still? Engine running, I assume?

Could be center diff solenoid. I've seen it a lot lately at the shop. The car gets stuck 4wd locked up and not letting there be a speed difference.

Torque bind.

Is the car an auto or manual

There's a few things that can cause this. First, check and make sure that all tires are the same size/brand/wear. I got my first subaru for free basically because the previous owner put one band new tire on with three old ones. This burned out my duty c solenoid, and can also cause damage to to the center diff. (This was on an auto)

If that looks good, try doing a transmission flush. If that doesn't help, then things are going to get expensive.

Mine does the same, pretty sure since I bought my car almost 2 years ago. I've never really paid much mind to it. I wouldn't be surprised if my diff is off though since I've been running marginally different sized tires in the rear for a while now (passed 2 months). It hasn't gotten worse since I bought it though and it's not often at all that I'm turning that sharply.

I'm not saying you shouldn't look into it if you plan on having the car for a while, though.

(mine is an auto)

drama.

Power steering would be the first thing to check, then the more serious differential problem...my PS fluid was low and it caused the car to not turn smoothly at full lock.

Try ATF flush if automatic first, and if thar doesn't work fix center diff. If manual just gotta replace. But like the others said check tire dizes and even differences in brands.

The center diff is not free. If it's an auto trans then it might be an electrical problem. If it's a manual trans then the fluid in the LSD is 'gummy'. I don't know about '02, but earlier ones were sealed, so changing the trans oil doesn't help....

^ +1 on Center diff. Mine did the same thing- only after a drive. It isn't too hard to do DIY style. 4 hours or so with little experience. There is a few how to's posted with decent pics if you search a bit.

It's definitely a DIY project for anyone who's willing to try. The parts are either $400+ for a new diff assembly or you can chance it an get a used out of a junk car. The latter will give you a chance to pull one apart without the worry of messing anything up so when you do it on your own transmission you will know what to expect.

I'd say viscous coupling inside the center diff, and you saying it doesn't do it when it's cold further makes me think that. Mines does the same exact thing, after 15-20 min of driving, slow and sharp parking lot speed turns is when the problem becomes noticeable.

+1 on the whole center diff having to be changed. My problem isn't so bad, so I'm just not doing anything about it until it gets so bad that the car just stops rolling haha
