Just curious, I have 115,000 miles on my 07 original struts and control arms. The bushings are cracking but no noise yet.
I know soon enough I am going to have to replace everything suspension related.
Anyone else get really lucky on their stock components longevity?

The rears will start to leak damping fluid, first. You're close. Mine started to give up around 118K-120K miles on my '08.

My '12, though, I have a pair of OEM ones for the '08 in wait for when they start to fail in a few years. I have 78K on it, now, so by late-2021, I'll considering changing them. I hope they're similar enough to work.

The fronts, OTOH, seem to be okay for a much longer period.

FWIW, the '05 Cadillac STS (RWD) I had which the '08 LS-L replaced had Magneride. The rear struts on it, too, went first. I can't figure this out, honestly.

Not a chance. Rear air struts on mine bit the dust at 50K miles, and control arms on front at 69K miles. Count yourself lucky

Well this just reinforces to me how lucky I actually have been. I have a 2001 LS430 just hit 130K and since I bought it (2009 @ 80K mi) haven't had to replace a thing up front suspension, arms or ball joints (knock on wood). Not aware if previous owner did or not though. With only 130K lol I almost hate to get rid of it. Could for sure use them now but I backed into the front bumper about a year ago and minor as it is decided it was time to just start looking and I'm now finally getting around to it. Counting myself lucky. It's been a hell of a ride and looking to upgrade to the LS460 anytime now.
