Stop the bed squeeking

Not THAT thank you! Our Symbol sofabed squeeks when driving, especially as we go round a right-hand bend, Very irritating.

After much trial and error I've found the cause. The latch bolt catches into strike holes cut in the underside of the bed frame.

This means there is bare metal to bare metal grinding between the bolt and frame every time the bed frame jolts up and down with the motion of the van. I tried filing the edge smooth which worked for about two hours until it wore the edge rough again.

Not sure what the proper solution is as it's bad design - if I could find a suitable nylon insert that would stop it grinding but I'm not sure if there's room. Any ideas very welcome.

Thanks, excellent idea to try for starters.

A good shot of white grease has certainly reduced the squeek. Not entirely absent but less annoying now. Thanks for the suggestion.

They make plastic bearings, I've been using them for years. You may have to increase the hole size then push the bearing in.
Guaranteed fix!!
