I change tires every six months (summer and winter tires), so not sure about the wear. And the winter tyres are relatively new, and the clunking sound is independent of which set of tyres I use, so I don't think it's that. The front axels also seem fine, (one side CV joint is changed but it didn't do anything for the clunking, could ofcourse be the other one, but then the problem doesn't look at which way the wheels are turning.)

Hi thanks again for the info. Seems like the symptoms align with a worn/failed center differential. It got worse now in the summer with warm temperatures, and after say driving on the highway for a couple of hours and then parking (when turning the wheels). I can really feel the clunking then, which is starting to feel/sound quite bad (Not only can I hear it but feel it too). Going straight is no problem though. And yes it seems like I have to apply a bit more gas when accelerating while turning. How about if I find a rebuilt whole gearbox and replace the whole thing?

Thanks for your reply, No I'm not very good at taking apart this kind of stuff, or well the space/workshop is more of a problem, but it seems like it can be done without changing the whole gearbox. Paul

Hi, I would have a question regarding the center differential of my Subaru Legacy (BH5, 2.0 l petrol manual) I've been hearing a klunking sound when turning my wheels (both directions). It's mostly at slow speeds when parking or something, when the wheels are turned all the way to one side. It get worse when the engine is warm, and I guess it's the grease in the bearings heats up and doesn't do it's job that well anymore. I figured this could be a drive shaft output bearing problem (feels like the bearings where the driveshaft comes out from the gearbox/front differential are quite worn.) My concern is that there could be a problem as well with the center differential. And my question is how does the center differential in my 2000 Legacy work? Because in mine it seems to be locked. So that turning the front wheel turns the back wheel. (When I lifted up one side of the car, can't remember now which one we tested gearbox in neutral or 1st gear since it was done by a friend whos knows a lot more about this stuff than me). My second question is that I guess I need to replace the output front driveshaft bearings (gearbox/front diff side). Is this possible or do I need to replace the whole gearbox. Which one is cheaper if I find a used gearbox, and how much are they usually (so I don't get screwed ). Thanks for your help Paul
