With those miles on the clock almost everything in the front end needs replaced. Sub-frame mounts, struts, strut mounts, trans & motor mounts, sway bar bushings, cv's, lower control arm bushings, wheel bearings, tie rods, ball joints,and the sway bar could be cracked. Just depends on how much you like the car and how you want it to drive. My opinion is you should use the GM oem parts where you can to get the best feel, but it adds up quick.
