mine was squeeky when i first put it on. i don't have the deluxe interior that a lsi would have, so it rubbed on the inside portion. what i did was take a plastic binder, and cut it into strips to slide in between the hardtop and body, now it's quiet.
i also found the softtop to be noisy, and mine was in great shape but the rear zipper was torn. so i found a hardtop for $360 which was cheaper than a new softtop. besides it rains alot up here so i figured a hardtop was better suited for me.
