Moving mirror

[et2]

Well we finally got out to glamp this weekend. The first trip is always interesting to see if anything comes apart after its winter nap. About 30 minutes into our drive the drivers mirror starts moving slightly. Then it gets progressively worse. Finally at the point where it's turned almost parallel to the MH.

Find a exit with a Meijers so I had some room to look at it. I was afraid it was coming completely off and would hit another vehicle in the next lane. So got out the ladder and took off the face where the camera is. There are at least two set screws around the section of mirror where it attaches to the post. I assume there is a lip there that the screws sit under to keep it attached. One is easy to get at the other about 30 degrees behind the first and I could not get to. So I tightened the front one that was accessible. It snugged the mirror into place.

While driving I could see the mirror still had a slight wobble but didn't move. After reaching our destination I check and it was still tight. Just wondering if the two set screws work together the secure the side to side movement and one the up and down?

Anyone ever have this issue?

Coming home it was fine. I guess tightening it worked. But those mirrors sure wiggle inside the housing while driving. Probably why it loosened up. Thought about using Loctite thread locker purple on it. If it happens again that's the fix I'll try.

Go on the web site of the company that made the mirror. Find your mirror and the schematic for it. That should show you where the adjustment and locking screws are. My passenger side Velvac mirror wants to rotate by itself and I have to snug up the locking screw regularly.

A little hard to comment without knowing what rig and mirror you have.
Is it the mirror or the arm that's loose?

A picture or two might be helpful here; there are quite a few different mirror designs.

I had some trouble with loose mirrors, but mine are evidently an entirely different deign. In my case, the fault seems to be wear on the shaft that the mirror head is attached to (which is held in with a sort of saddle cap arrangement, not unlike the crankshaft or connecting rod bearing caps in an engine). I believe I have solved it by interposing a shim of thin metal between the clamp caps and the shaft, though time will tell for sure; I haven't traveled far since the repair.

That's apparently not very applicable to your situation, though.
