Wheel replacement help
I have a Specialized Hardrock mountain bike (purchased 2002-2004). While doing maintenance on the rear hub, it was discovered that the rear hub was pitted and damaged as well as the cone. So a new wheel is in order I believe. How can i match up the wheel with the freewheel? or do i need to look for the wheel and freewheel all in one? Or am i completely wrong about all of this?
the freewheel is a shimano mf-hg37. No information on the wheel except on the rim it says X-RIMS Z1000 ETRTO 559x20 26"x1.5".
Thanks in advance. and this is my first post so hope i got all the information included. if not, please be kind

A bit of pitting is not necessarily a wheel killer, you might get away with
replacing the balls and a generous lubing, especially if you ride off road
mostly. There will be increased friction but doubt you would notice much.
If you want to replace, this would be a good opportunity to do a minor
upgrade to cassettes and a freehub wheel. 7spd cassettes are not much
more than freewheels and you could easily upgrade to 8-9spd by a
fairly inexpensive shifter change. The deraillers would work as is. The rim
could be recycled to a new wheel, maybe even the spokes though most
posters here would recommend new spokes. If you are a fly weight and
doing non technical riding and the spokes haven't been damaged by
chain derailing into them then you could probably get by. Spokes are best
changed however, and a good eyeball on the rim for brake surface thinning.

If the races are badly pitted, you'll need a new hub.
I'd agree with SCH and upgrade to a cassette & Free Hub. Easier to service and a wider range of cassettes are available than Free Wheels.
You could replace the hub using your old rim, but by the time you pay for labor & new spokes, you may as well buy a pre-built wheel.
Another option is to look for a donor wheel of a Craigslist or similar bike. That's what I did when I had a R wheel stolen. I picked up a bike with a Free Hub for $20!

Thanks for the replies, I really do appreciate the time.
First off, I would prefer to replace the wheel and not mess with replacing just the hub. All things considered this sounds like the best choice.
Would switching to a cassette & free hub require purchasing anything else besides the wheel?
And how do I select a wheel for this? there are sooo many choices.
Thanks for the time and patience.
