i was getting an alignment when i found out all 4 of my struts need replacement. the guy showed me and they look like there were rusted through. I have a 2007 530i with 120k miles (no sport package) with 172Ms. I haven't replaced the struts yet. i'm try to save a little money by picking up the parts myself and having the shop install them. i found the OEM Sachs struts on fcpeuro.com for a decent price (~$194 for each front, ~$120 for each rear). is there any other hardware that I need to pick up besides the struts themselves? I heard that you should replace the bump stop too. Also, how much should I expect to pay in labor?

Thanks!

 

replace all mounting nuts at the upper mounts (both front and rear). replace both rear lower shock mount bolts. at that mileage, id seriously consider doing both rear shock mounts and both front strut mounts as well.
