A flutter, rattle or similar wind noise may be heard from either the left front end and\/or right front end of the vehicle at highway speeds on some 2021 Tahoe and Yukon models. The sound may seem to be coming from the windshield area. <\/span><\/p>\n

There may be excessive movement in the area (Fig. 23, #2) of the left or right front inner wheel well liner (Fig. 23, #1), resulting in the flutter sound.<\/span><\/p>\n

To correct the condition, apply a 1\u201d x 3″ x 1\/4″ piece of foam, or a couple layers of butyl tape, to the inside of the fender. <\/span><\/p>\n

It\u2019s necessary to partially remove the front wheel well liner to obtain access to the back\/inboard side of the front fender. The back of the fender should be clean of any dirt, mud, etc.<\/span><\/p>\n

On the back\/inboard side of the fender, the foam or layers of butyl tape (Fig. 23, #5) should be applied starting at the fender feature line (Fig. 23, #7) and 10mm from the fender flange. (Fig. 23, #6) The foam\/butyl tape needs to create a cross car interference with the fender liner return flange.<\/span><\/p>\n

 <\/p>\n

It may be necessary to use a trim stick or similar tool to pull the wheel house liner to the full forward position when reinstalling the wheel well liner. With the foam\/butyl tape installed, there should not be any fore\/aft movement when lightly pushing on the wheel well liner.<\/span><\/p>\n
