sounds like you have 1 or more CV joints going out. try this: in large parking lot, crank the wqheel all the way to one side, come to a stop and then accelerate to low speed (ie, regress to your teen years and do donuts!)....if you hear a clunking noise or something like someone cracking their knuckles, it's very likely the CVs. these are a normal wear item.
CV joints are the modern version of a U-joint and there are 2 on each axle of an AWD Sub. the rubber boot usually goes before you begin hearing noise....look to see if you see torn rubber and grease spewed and flung in the plane of axle rotation. this is a nearly 100% positive sign.
altho Sub CVs don't seem to go out as fast as Amurrikin ones, your car is definitely in the mileage range where it's possible. what often happens is that a rock or something hits the old, fatigued rubber boot and tears it....then the grease goes out and water and dirt come in, with predictable results for the actual metal parts of the joint. it's usually always the outer ones that go, i'd guess due to flexing further and being more exposed to damage than the inner (nearest the transaxle) ones.
lots of outfits rebuild the axle shafts and sell the complete units, and this is usu the cheapest long term solution. far cheaper than yr mechanic's labor to do it himself.
altho this may not be the problem, i'd definitely eliminate it b4 looking at more expensive possibilities. one of the few items that you can do decent diagnosis on even if yer not mechanically fixated, er, inclined.
