Naughty BC7

All the strange phenomena have thoroughly disappeared in BC7 SUBARU Legacy LSi US model, tight corner locking and breaking, how come? I don't feel good on this kind of opportunistic trouble on earth! I'm prepared for the replacement parts of rear transfer clutch mechanism, 5 sets of driving clutch plates, a valve body gasket and a case gasket also with transfer mounting insulators R/L. And the D-day is planned for the day after tomorrow and the next day? Again this 20 years old mischievous and naughty automobile makes me fall into the situation at a loss how to do!
