How To Level Tow Mirrors On A GMC
 

Information posted by reyb.

1. Remove the plastic cover that is covering up the hinge part. Be careful
because that piece of plastic has a sharp edge; I cut myself the first time
I pulled it off.

2. Inside you'll see 4 phillip screws that is holding down the hinge; remove
these and let the mirror hang down.

3. Take the hinge clamp off from the mirror post. The clamp is what the
phillips screws go through and the mirror post is what the clamp goes
around.

4. Cut each side of the hinge clamp right in the middle.

5. Bend the top of the hinge clamp at the screw hole inward
such that at the cut it is bent outwards the same thickness of the metal
itself.

6. Bend the bottom of the hinge clamp at the screw hold inward as well
such that at the cut it is bent inwards the same thickness of the metal.

Note: Steps 5 and 6 may be confusing but visualize what you
are trying to do and it'll make sense. The reason for
making these bend is such that the mounting surface
where the clamp meets the mount base is square.


7. Insert 3 washers between the top of the hinge clamp and the mount base
and get some longer screws in which to secure the clamp. The washers
about the thickness of a penny. The new screws on top were about 15mm
in length.

8 Trim the plastic cover a bit where you see it rubbing.

ive heard that if you use two washers instead of 3 you wont need longer screws and it levels out pretty fine too

well i should be doing this in the next week or so my second mirror should be in on wed
