Rear hub question

I have a rear hub that I think needs to be re-greased. The hub seemed to have a flat spot on it. I replaced the rear tire and managed to loosen it up so the flat spot went away. But there has been times that it seemed the brakes have been appllied while riding and I did not apply them. I have a Raleigh Venture 4.0 that is about 4 years old and has almost 250 miles on it (yes I know that the mileage is way too low for the time that I have had it).

So the question is can I re-grease the rear hub? Just tried to find the specs on my bike but the raleigh site is down at the moment.

Thanks for your help.

Yes, you should consider regreasing the hub. As you disassemble it you might find a bearing surface with some damage or an axle that's bent. Both could cause a binding. But the amount a bearing binding can be felt when riding is very small, very small unless the bearing was WAY over tightened to begin with. I wonder if the binding is something else. perhaps rim/brake related? These causes are FAR more likely to be felt during riding. Report back with your findings please. Andy.

First off you need to realize that bicycles are very generic in their design. Not finding what you want on a web site sharing the same name that's on your frame usually isn't much of a loss. Sheldon Brown and Park Tool has tons of online info on bicycle repair, start there if you want to read up om diagnosis, repairs, parts and tools.

A simple adjustment may be enough, and more often is the problem than lack of grease. It's not like a car where you just push in more grease. As noted above you need to inspect for problems. Also you will need specialized tools to do the work.

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!

The ParkTools page recommended above is excellent.

When reassembling you may have bearing-balls held in a circular pressed metal cage. These are used by manufacturers to speed assembly, they are easy to fit but only go in one way around - there is an inside and an outside to the cage arrangement - you'll soon see which way. If you have loose bearing-balls then it's a bit fiddly - there are a couple of ways of dealing with this - either stick the bearings in place with grease a la ParkTools - or alternatively if you have a few small magnets you can stick them around the outside of the hub and the bits will stay in place nicely.
