2008 F250 Manual Extending Mirrors

Went to extend the mirrors a week ago. The passenger side slid out slightly stiff but nothing to be concerned with. I've since worked it a few times while rinsing with water and it now seems normal.

Drivers side, after several tries and it felt like I was going to rip the entire assembly off. The whole truck was rocking. I finally gave up and drove with it in.

Any ideas how to free it up without breaking it?

    I have these mirrors. Try alternating taping near the upper and lower arms with a rubber mallet while pulling. Like someone else suggested, armor all.

    Went with the dry lube.

    Got the upper arm to move a little (1/4inch) in and out but the lower is still rock solid after hitting it with the spray lube.

    I would try spraying some WD up in the sliding part. That may loosen it up some.

    Did it slide before?

    Thanks!


    No we picked it up last fall and wound up not towing with it till this spring. Never thought to check if the mirrors extend since they are simply a friction fit.

    I'll try the WD-40.

    That plastic expands and contracts with the weather. Use Armerall on it....it's petroleum based, and will make the black plastic shine like new.


    Not trying to get it shiney...trying to get it unstuck.
