1. Replace the Front Handles/Latches: Installing updated, redesigned front lift-off roof panel handles that provide tighter clamping leverage. Available Here!
2. Install O-Rings: Adding small rubber EPDM O-rings onto the front locator pins to isolate metal-on-metal or plastic-on-metal contact.  Available Here!
3. Lubrication: Thoroughly lubricating the front guide pins, rear pins, front latch bushings and stainless ramps, and contact weatherstripping using ACDelco Super Lube Available Here! to stop friction squeaks.
