Decided to strip and service my hubs as they were a bit rough. Stripped cleaned and inspected, with no pitting to cone , cup or bearing. Re greased and put back together. Made sure the axle was centred and tightened the cone finger tight making sure no play. Locking nut put back. Trouble is now, the wheels are actually rougher than before.
What have I done wrong ?

Quick release or bolt up?

If Quick release the axle compresses so you actually need more play before you tighten.

You could have tightened the lock nut up and its also tightened the cone.
You need to hold the cone with one cone spanner then tighten the lock nut against it.

There will be numerous videos on youtube, but as far as I can tell you have somehow managed to tighten the cone indirectly or you are using a QR.

dicki

did you really clean it all out
sometimes old gunk can contain particles which will grind

did you lose a bearing ?
did you put the bearing cage (?) back in the right way round ?

I think you've got one too many or one too few bearings in there!

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
