Garage door/opener noisy
Our old Stanley opener broke over the weekend. Had a 1/2" Craftsman chain drive ready for when it died, installed it in it's place.

I had thought that the old opener was responsible for most of the noise but it seems it's more the door.

It's a sectional wood door, single large spring. I tightened up all the 7/16" nuts and lubed the wheels and any other moving parts (not the rails though).

Is there anything else I can do to quiet the door down? Is it worth replacing the old steel rollers with nylon?

IMO, replace the door. If this is a 16' wide double door, a 1/2 HP opener is not enough with a wood door.

I dunno what the door weighs or what size craftsman motor you need. But 1/2 horse is common for double wooden door. It all depends on gearing, small motor can lift heavy load but slowly with right gear ratio. Is door raising lowering at same speed as old? Does motor seem to be straining or over heating? Was old unit chain? Chain is louder than screw or belt.

As to noise, the wooden door, especially panels, is a sound board magnifying all sound.motor chain wheels, bearings etc. Under powered motor may be straining making more noise. Nylon wheels are quieter but will wear out faster, especially if door is heavy. How much faster I dunno. metal on metal is loud.
Cheap way to insulate door is with styrofoam panels from HD. about $10 for 6 14X48 panels, 3/4' inch thick. Light weight, all 6 weigh 2 lbs. cut to fit panels of door glue in. Not real durable to knocks and banging into. At price is worth try. You can pad metal to metal connections with fiber or rubber washers and grommets. The various hangers and brackets.Pads between actual metal surfaces and under nut and bolt head washers. Cieling is also sound board, especially uninsulated one. Isolate motor brackets, any other ceiling mounted things from ceiling with stiff resilient pads. Those inexpensive, easy , tries. after that you start to get into real engineered sound deadening ideas. Small boy living in garage to open and close may be quieter except for whining and complaining.
