I am confuzzled at the moment. is the tension strut the same as a Control Arm/Ball Joint Assy? Moog lists as the latter and the service tech manual lists as a tension strut. Are they the same thing or am I not looking at the right part in the service manual. And the plot thickens... the mechanic said I need the tension struts replaced for $450 includes an alignemnt. Does this seem reasonable. I want to be able to do the work, but am somewhat mechanically challenged. I desire the experience. What's you'alls opinion?
