differential help?
			 
			 
			
		
		
		
			
			I am getting major chatter when full lock turning and is getting worse. It goes away when I go to open center diff. I changeed the oil tonight to Royal purple 75-90 wt. synthetic and took it for a test drive. It semmed better but still pretty bad. Should I forego  running tomarrow? Any advice or help will be greatly appreciated! 07 STI
