My Subaru Outback 2000 has a shudder/vibrate noise from front when turning sharp to right or when backing up at idle to low speed otherwise do not notice it. Wondering if it could be the axle the right one was changed at 92,000 miles in 06 . I plan on doing mayself as just spent $$$$ having new head gaskets installed. Also wondering how power steering racks hold up in these cars had power steering flushed recently. Does not make noise when turning wheels at a stop.

Thank You , Tony

Could be . . . . "torque bind".

In brief, when moving slowly (at idle or near) in a sharp turn (as when parking), the car will seem to shudder or shake, or seem to move and then slow and then move again. It's caused by the AWD mechanism remaining engaged tightly when it should allow some slack because the front and rear wheels follow different paths when turning.

The symptoms are often confirmed by driving in tight circles (left, then right) on a large flat area such as an empty shopping center parking lot.

Is the transmission manual, or automatic? If manual, the center differential viscous coupling has failed -- only fix is to replace it (or the whole transmission). If automatic, it could be a failure in the multi-plate AWD clutch control solenoid or the clutch itself. Sometimes, changing the ATF a few times with some driving in between will help flush out any material that might be causing the problem.

Do a search here for "torque bind". Lots of posts, threads, and ideas.

P.s. What about the tires? Are they all the same make, model, size, and tread depth?
