I replaced the front struts only because the shop that replaced the rest of the "stuff”, who by the way had originally told me the struts were "OK", changed his mind after I returned to him because the "Thunk" continued. Needless to say, I took the car to another shop for the Wheel Alignment. The Technician there also noticed the New struts in the front and the Old struts in the rear. His determination was the Rear struts were "OK" for now with no signs of leaking BUT I should think about replacing them in the future also. At this point, I'm waiting for the LCAs to arrive from the WWW.Amazon sight I bought them from for $43 ea. but I'm heading out today to Autozone for the Engine Mount. The temp is supposed to get up to 65 and sunny...perfect for driveway wrenching.

Thank you all for your replies. What more could you ask for here than all of your Bright minds coming up with practical solutions to our sometimes problem vehicles!
