Gasket around Cab Over window is coming loose

The gasket around my front cab over window is coming out of the window track at the corners of the windows where it curves. Any suggestions on how to fix this? I tried several times pushing the gasket back into place but it keeps coming out again after awhile.

I did have this gasket replaced several years ago at the RV service place and it was fine for the next several years but the problem is now back. Do I have to have it replaced again? Does it shrink?

Would any sort of sealer or adhesive prevent it from coming out or pulling away? Do they usually put some sort of gasket sealer in it to begin with. It does not look like any sealer or adhesive has been used.

Appreciate any and all suggestions.

TIA John S.

    Your problems can't compare to our first rig here ordered in 1983. The three curved & domed cab-over windows were a true curse, trouble from the first year. I messed with them on occasion for 24 years until sold in 2007.

    To think we could have requested the rig be made without those windows when we ordered it. :S

    AFAIK, these gaskets are installed dry, but I don't really know. The gaskets are not used to seal the window but they probably help to hold the glass in place.

    Thanks for the feedback... Nobody replied to the gasket sealer question. Do they usually use some sort of sealer or adhesive when they put these gaskets in?

    thanks again, John S.

    When they first start shrinking you can push them back in. Use your thumb and push hard until you feel it 'click' it to the slot. Then run around all of it pushing it back into that slot. Eventually they shrink too much and won't stay in.

    That will happen to all the windows eventually, only way is to purchase new rubber and redo the rubber gasket, since the old gasket is dry and shrunk.

    If you really want it fixed right. Call Custom R.V. Services in DeForest, WI. Talk to the owner. He really uses good stuff. But the work is not cheap.

    They are maybe three hours from you. They have done great work for me on two RVs.
