One drop of 30 wt oil at each bearing will quiet the thing for a while, but you will eventually want to replace it. Also consider the whole fan is about the same cost as the motor, and easier to find.

The motor is a common item to need replacement in bathroom vents. Replacements can be found just about anywhere that deals with electric motors. You might even be able to get a replacement where you originally purchased the unit. There are dozens of web sites that you can locate a replacement. http://www.electricmotorwarehouse.com is just one. Simply do a web search on replacement bathroom vent motors. Also if the are able to purchase items from wholesale vendors you can get one from Grainger's. It should cost around $20 to $25
Part # 62345-000 (replacement motor part #).
However there is an alternative to replacement. This depends entirely on how handy you are with these kinds of things and how bad off the motor is. If your not comfortable with repairing this kind of thing don't bother with the rest of this.
I hate to replace anything that may be repairable. Unfortunately my friends know this and recently one asked me to look at his NuTone bathroom vent motor before he replaced it.
For the cost in time of an hour I was able to refurbished it.
A good way to check if it's a candidate for repair is to check how much play is in between the shaft and bushings. If you can feel movement then it's best to go ahead and replace it. If the problem is that the shaft is tight and just hard to turn then it may just need some cleaning and fresh lubrication.
The steps are simple. Once you have the motor removed from the vent cage you will see a pair of nuts and bolts holding two brackets in place. These brackets(one on either side of the coil) are what hold the shaft centered and house the bushings. Remove the bolts and the brackets. Be careful not to lose any of the washers on the shaft. These are spacers and need to be replace the same way they went on if they come off. All you need to do is clean both ends of the shaft put a little oil on the shaft and in the bushing and put it back together. If the motor has a plug and not just bare wires for reconnecting to the power supply then it's safe to just plug it in to any outlet for testing after you remount it in the vent cage. You will know right away if you were successful.
Hope this helps.

The C-frame motor for LS100SE (P/N 62345) is no longer manufactured, and no replacement is specified. I checked with Nutone customer service if the motor for LS100 (P/N 89169) will work. They said the blower housing is the same between the units, so it should work mechanically, but the plug configuration is different requiring some electrical changes.

SOURCE: I have a nutone 8830
Take down the cover... they usually snap in by a set of spring wires...then looh ofr a screw or a couple of screws that hold the motor assembly up in the box. If there are no screws then the plate that holds the motor just snaps into the outside box....if that is the case just take a screw driver and pry out slightly on the outside box and snap the plate out and drop it down...
The motor will then just be a couple of nuts to release it from the plate...the fan cage often just pulls off of the shaft.
