Got these two lock-nuts (photo attached) which one would you say is correct..

The lock-nut is to fit rear hub on a 2005 Fabia VRS.

Hi Giandougl

When I did mine the new nut came with the new bearing/hub assembly. Both old and new nuts were 30mm size.

So that's the size I suggest you go for.

Whichever fits the threads and goes tight!

If your that worried, compare it to the other side.

Thanks members for your input.

As both sides are the original hub/bearings I can compare nut dimensions upon removal.

Just wanted to make sure I had all the correct bits before taking the job on.

Contacted retailer who will issue the correct nut, so problem solved.

 

Turns out it is the 'brass' coloured nut still being 30mm (not 28mm as I previously stated) as the silver coloured nut, but the brass one has a much larger collar.
