Had a Yakima Vipor's mount hinge pin work itself almost all the way out. It's a splined thread of some sort... Whatever, been using the passenger side mount because I'm too lazy to contact Yakima. Their website sucks! No links to contact ANYWHERE! So, I'm pretty frusterated, since I've only had the rack for 8 months! I do have my bike up there most of the time though... It shouldn't matter though, that's what I paid $600 bucks for! It's a gad damned bike rack isn't it? I'm pretty pissed off now and I'm gonna launch MS Word and write a letter... gotta' go.
