I just replaced the front lower control arms, front wheel bearings and back hub bearing assembly.
 
	 
 
	Looks like I will be changing both rear and front struts soon!!
 
	 
 
	Besides, I just bough 5w-20 synthetic motorcraft oil... Should I be worried if I am moving from semisynthetic to synthetic oil? I have heard that synthetic has detergent that may clean and cause problems in the pump or filter?
 
	 
 
	BTW, I drive a 2007 MKX AWD, 140K
