I second this. I love the rack and feel like it's sturdy and functional however the creaking noises from the front stabilizers drives me crazy too. I feel like a larger rubber section on these might make all the difference. Who knows maybe @lodoffroad will find a solution to this in the future. If this were fixed the rack would feel like something that should have come from the factory....
For me the one real annoying thing that bothers me are the two pairs of leveling bumpers on the front stabilizers. The white piece that is on the top portion of the windshield. Those two always make creaking noises when I hit a bump or pothole. Drives me nuts
