rear wheel problem

Problem started since I rode for several hours in heavy rain.
First, I noticed more resistance while riding the bike.
Then, chain starts to fall off from the largest cog on a hill. It is a
down tube friction type shifter. Shifter moves back when I apply pressure
on pedals.. I need to keep holding a shifter while climbing a hill.
And then, the rear wheel started to make noise when it turns.
These problems started to show up at few days interval.
Is this lublication problem at freewheel ?. Any suggesstion ? TIA

bearings full of grit. needs to be stripped & repacked with grease &
bearings replaced - if damage is not too severe.

The noise sounds like it could be the freewheel, they make a pretty loud
sound when dry.
Pull off the freewheel, hold it such that the teeth are facing the palm of
your hand and apply regular motor oil so it runs down in the opposite side.
Spin the freewheel and the noise should go away.

As for the shifter slipping, tighten up the shift lever.

Clean and repack the hubs with grease.
