Ribbed Roof Installation Guide Jeep Cherokee and Grand Cherokee

Composite Frame Sunroofs [see illustrations] Composite frames are not as rigid as metal, and tend to twist inward when installed in ribbed or thick roof skins. Use silicone sealant to seal the frame against the roof, and shims prevent the frame from bending out of shape. Procedure: Measure and cut sunroof hole as usual 2. Cut strips of 3/16? thick material to fit between each rib at the sunroof hole. Run a bead of non-corrosive silicone in troughs between ribs and set strips into it. Fill any gaps with silicone. Objective is to create a flat area for sunroof to seal against.

Clean overrun. Allow silicone to set to minimize shifting while installing.3. Cut strips of 1/8? thick x 1/4? wide material to fit between clamp ring and main frame. Glue to inside edge of clamp frame, between screw holes. Without this inside shim, the sunroof main frame will twist, causing gaps between the glass and seal which will result in water leaks.
