Front Wheel Hub Nut Loose
Posted 23 January 2013 - 05:15 PM
Took my car for its MOT test today and it failed on front wheel bearning having excessive play. (I take cars to local council garage who do not fix cars,only test them!). I thought it was a bit odd as I only had a new bearing and drive shaft fitted a few months ago. Anyway, got it home and in the garage and jacked it up to have a look. Turns out that the hub nut was loose so I have tightened it up and now the 'excessive play' has been cured. My question is - should the hub nut have a locking device as cars I have worked on before have always had a split pin to hold it tight.
Incidentally,I only tightened it up with a spanner so will get a socket - think it's a 32mm if anyone can confirm?

Ideally you need a complete replacement hub - you could risk one from eBay.
This is the bit that wil have worn (this one's from a Focus, but you get the idea)

You don't want it coming loose again as it will very quickly knacker the wishbone.
Fingers crossed it was a simple slip up by the mechanic. Also the hub nuts aren't really meant to be reusable, so would be sensible to get another.

I'd absolutely reckon that the mechanic forgot to finally tighten it. The normal procedure would be to nip it upwith no weight on it and then to finally tighten when the wheel was back on the ground. It's the easiest thing in the world to get distracted and miss a step in the process. Unfortunately human error can never be eliminated completely and this is not a reflection of the capabilities of your mechanic. Someone I new a few years ago took his VW camper in to a VW main agent for service. Three miles after collecting it the engine seized. They had forgotten to put the new oil in! Took him months to get compensated.
Sometimes there's two nuts on a spanner, the one being tightened and the one doing the tightening.
