Just swapped the winter tires on today. The rear hard lines that run along the suspension arms on mine have lost the outer protective coating and are rusting. Cleaned them up and rust proofed. But the plastic guides seem designed to trap crud. I'll just have to clean them more often and keep an eye on them. Or wait for the puddle :)

For me, it was a lot of rotted leaves that did me in.

Just traded her in, though. May go for an e70 next year. ;)
