My washer LG WH2277HW won't spin and it has a burning smell to it.

Yes, change the pulleys too. You can buy a kit

Holly, always easier to buy an assembly, but probably a lot more expensive. If you can remove bearing and take to a industrial supplier and get matching bearing, the cost would be a fraction of that of a new drum assy. If you or a friend can do it, go for it.
You may want to get a second opinion on what you are smelling, it very well could be the drum rubbing gasket if it is a burning rubber smell.Maybe call a good appliance Tech. have them diagnose and estimate repair. Check LG washer bearing link below.

Generally not filling fast enough or ole water pressure or no water flow at all. If water is fully turned on, then check hose washer filters in hoses or filters in back of unit where hoses connect for clogs.

Smells like, I mean sounds like, a belt is burning either from friction caused by a bad bearing, or, a loose belt is slipping on the pully a bit, causing it to heat up from the friction.

its probably the drive belt that you smell burning under the basket,but there are numerous things that can cause it to burn,so you need to find where its froze up could be a clutch,the brake,the drain pump

Couple of things....let's start with the easiest. You know where the little panel is, where the "drainperiodically and remove any lint" service port is? Check to see if it has the cap or plug tightened down. We will go from there.

The belt could be worn and will be slipping on the pullys, as it spins up the rubber , rubs against the pullys and that is what creats the burning rubber smell, the belt needs replacing.

You will need to have it checked by a qualified LG technician to see what is the deal with the burning odor.  And the noise is probably the washer not balanced correctly.
