: Has anyone noticed this but when I put my sunshade up or down, it shakes and doesn't go down smoothly like when you put the windows down. Is this normal ? I tried it out for the first time yesterday and this is the first thing I noticed. Thanks guys.<p>Frank<p>The sunshade has wheel guides (one on each end corner) to guide the shade as it moves up/down the rear glass. Verify that the wheels are actually making contact with the glass and that they are not being forced to hard into the window causing excess friction/pressure. This could generate an unstable effect as you move the shade up/down. Should be a simple adjustment.<p>Mr. Vanos
