I don't have the smoothest ride but hey, it's my LS and not my Town Car. I'm almost certain that my Rear Struts were factory installed - 149k miles ago. Thinking I should replace them (and the springs?) and am wondering if this is a simple procedure. Does one simply remove the bolts and install a new assembly? I did a search for a video but came up empty-handed. I can get a completely assembled Strutmasters kit delivered to my door for $385. I was under the car and spotted this piece of tape across the bottom of the Coil Spring. Is this put on at the factory? If so, it's confirmed that my current setup is indeed, 149k miles old.
