Side Mirrors shaking on high speed is a very common problem in the Jeep Commander and usually the dealer replaces the whole mirror under warranty to fix such problem. In my Commander they replaced the mirrors three times (two right and one left) !! ,, that is not good option for those with warranty expired like me, I'm not going to pay $100+ for a new mirror which will shake sooner or later !
So I took off the mirror and tried to take it part to see how this can be fixed, Surprisingly the mirror is not easy to take a part (or at least I couldn't find a way to dismantle properly), but while I was examining the mirror to see what is lose, I moved the inner mirror to the far end of one corner so that I can see the component inside and I noticed that the mirror is attached to the motor by four sort of clips and the those are not tightly holding the motor mount and shakes by hand!
Photo shows from where you can see the clip:
And this is one of the four clips I'm talking about
and the this photo shows the location of the four clips:
and this is a video for the clip when shaking the mirror, and here you can see the loose clip:
so I thought that if I glue those clips it would solve the problem and so I did.
I started by cleaning the clips in preparation to put the glue on, and I used this brush, you can use smaller one if available, I also put some water in it:
Then I let the water dries and then started to glue the clips, I used this glue, you might use a better one that is more suitable for exterior use and dries fast.
I just put a drop or two in the middle of the clip ,, this blurry photo shows the glue area:
I could only manage to glue the upper two clips as the glue simply drops down when trying to glue the lower clips but its better to glue all four (if you manage).
So I went to test drive it and see if that worked !! I drove at 100 MPH
and the mirrors are not shaking at all
I hope that I delivered the idea and make clear, and excuse my poor language.
lets see if you guys manage to get it fixed this way and feedback your comments to update this and make a HOW TO FIX thread.
