new balls for the rear axle- is this a difficult replacement?

So a friend told me he has a pretty nice road bike he'd let go for a very reasonable price, only thing is that he said it "needs new new balls in the axle, on the rear rim, where the 6 star gears are. The section that goes from one side to the other has no balls in it anymore. That is what makes the rear rim run. Currently it has no balls in it so it cant run properly."

I have a bike coop near by that allows you to work on your bike with mechanics nearby, or I suppose I could just pay. Is this a hard fix, or is it cheap to just let a mechanic do the work?

From your description and use of terms I would recommend either paying to have this fixed or to use the CoOp with some close supervision/dedicated help. This is not a difficult repair but can be turned into one when one does not know where to begin or what they are looking to do. There are plenty of free references on overhauling hubs on the internet.

In general here is what is required:

1. You will need to Remove the freewheel - this is what you are refering to as the 6 star gears and this requires a special tool.
2. You will need a cone wrench and regular wrench in appropriate sizes to open up the hub.
3. If there are no balls in the hub you will need to research the hub make/model or otherwise figure out how many and what size balls need to go in it.
4. You will need to inspect the surfaces the balls run on for damage such as pitting.
5. if damage is present you will need to decide whether it worth completing the overhaul or scrapping the hub/wheel.
6. If no damage is present or there is but you decide to complete the overhaul you need to pack the bearing cups in the hub with grease and then place the appropriate number of balls into each cup and reassemble the hub.
7. The final step of the overhaul is setting the proper preload on the bearings and locking it in with the axle locknuts.

Like I said above, there are plenty of writeups and videos on the internet that give step by step directions on how to service a hub but having someone help you through the entire process the first time will be of immense benefit.

Do you know what it might cost? Having someone do it, or how much for the parts if I do it myself?

The price had better be VERY reasonable as it sounds like the rear hub may be damaged beyond repair. As recommended, have a knowledgeable person at the Co-Op look it over and see if it's salvageable.

+1 on the above comment and recommendation.

From your description it is hard to predict. If the hub's bearing surfaces have significant damage an overhaul will not have very good results and the damaged bearing surfaces will continue to deteriorate and deteriorate the new balls. Overhauling a severely damaged hub is like putting perfume on a pig.

If there is no damage or the damage is slight then I would overhaul it and ride it.

Normally, a routine overhaul for a hub should run about $30 (+/- $10-15 depending on the area of the country you live in and how posh of a shop you go to).

The problem with your project is it is not a routine overhaul...in fact you don't really know what is going on inside the hub at all. It was interesting and surprising to read your comment that said there were no balls in the hub. Are both cones in the hub? Are both locknuts in the hub? Is the axle intact? if the axle is not broken is it straight? Did this hub come with spacers on the axle and are they present or missing? These are all questions that are pertinent to the amount of work and the parts that might be needed.

On top of that...a hub is not an easily replaced item like many of the other parts on a bicycle. Most parts are "plug and play" as long as they are compatible with each other. A hub, on the other hand, is laced into a wheel. It is a lot of labor to unlace a wheel and rebuild around a new hub. For a 6 speed system it may be entirely cheaper to just buy a new wheel and transfer your freewheel over. A new wheel will probably cost you somewhere between $50 and $100 (+/- $20 for the same reason noted above).

***OR***
You might find when you open the hub up that the balls are there and the parts are pristine and this will be just a routine overhaul which should take you less than an hour and cost a couple of dollars worth of ball bearings and grease + CoOp shop time.

Hard to predict either way in this case.

Good luck with it though.

IF the bearings are missing, I'd expect the hub to be possibly damaged beyond repair.

IF you want to actually buy this, I'd get a "take back" clause in your "contract" that the hub is repairable.

Worst case, you could buy a replacement rear wheel for under $100 if you aren't too fussy about "bling factor" and have a reasonable deal. Assuming there aren't "other problems" that are masked by the inability to test ride.
There's also the possibility the hub isn't damaged, but I don't think that's real likely.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!
