If your unit is quiet when pulling and loud on decell then chances are excellent that the pinion nut has come loose. This is not remotely uncommon as our friend in South Africa had the same issue a week ago in another thread.

For a first whack, and without any special tools, I'd say lock on the handbrake and tighten the nut about as much as you can with one arm and a 12" wrench. Take it for a ride and see if it's better. If you like it, reach in with a punch and stake the daylights out of the nut. If it is merely some better, you could try making it a bit tighter. It is not as though you are going to hurt anything as the horse is already out of the barn.
