The skewer assembly IMHO is a flawed design, and here's why. The assembly is held together by a rivet that travels through the plastic cams and through an internal arm that tightens the fork clamps when actuated. The problem is that the rivet bends/loosens, resulting in 3 issues: 1) Once bent, the skewer fails to apply pressure to hold your fork, 2) The rivet can fall out of the assembly. The assembly will then come apart. 3) Once bent the rivet can cause the cams to flare outward, resulting in failure to engage with the aluminum facing, resulting in failure to put pressure on your fork. Thule will probably tell you this is user error, e.g. too much torque, a point that I would argue. I have been using Thule products for over 30 years with no issues such as this. I have 4 of these, and they are all doing the same thing, and they cost $45 to replace (each)! Thule, why not use a stronger/thicker bolt that is easy to replace instead of this rivet? Over the years I have spent quite a bit of cash replacing all of the cheap plastic parts that come with Thule racks. I don't have a problem with maintenance, but this product is just poorly designed and consequently rendered useless, just because of a cheap rivet.
