Front wheel/hub Split Pin rattle?
#1
Noticed a metallic rattle from the front , changing with road speed, and more frequent on bumpy roads. Scratched my head for weeks wondering what it could be, went to fit new Wheeltrims today and found that the drivers side front wheel has a split pin in the centre and the bit behind it (castellated nut??) Which is loose/rattling.
It doesn't look like it would come off, but it's definately loose and no doubt the cause of the rattle I'be been hearing.
What's the best way to fix this and cure the rattle?

Now I think about it, the local garage replaced the wheel bearing on that side a couple of months back, maybe the cause of all this?

First thing to is to check the front wheel bearing as not failed then take the split pin out then tighten up the castellated nut but do not over tighten just over finger tight they may of over packed with grease when they put it back on or some thing was fouling so it not fit on right or just take it back to the garage that done it and get them to check it

Thanks Jed, I'll have a look in the morning and try your suggestions.
Unfortunately I'm 400miles from home this week, so my "local" garage isn't quite so local lol!
It's been rattling away for a couple of months and a couple of thousand miles, no big deal, but pretty annoying I can tell you.

Ok so here's the cause of the rattle...

The hub nut underneath this was nice and tight, this just looks like a cover with a lock pin that holds it on (and stops the hub nut coming off completely if it were to work itself loose.)
Basically the cover was loose, and the pin was also loose, a quick press in the vice and they fit back on snugly and are now rattle free!
So a very minor issue but quite annoying especially when I had the window down or drove through town:lol: but easily sorted.

Sorry but that advice is very slightly wrong, it's not a taper bearing as in a vauxhall nova from the eighties, the front wheel bearing is either 280 or 325nm (depending on driveshaft size, that's the bigger size with the split pin) which is not just over finger tight, we use a three ft long torque wrench to tighten them ;)

As for the split pin, if you put the round end in a vice and gently squeeze it the pin will close up and then when you put it over the lock washer the slack you've experienced won't be there, it's quite a common issue with this type locking pin, used this fix loads

I know i'm bringing back a 4 year old thread, but, I stumbled upon this whilst looking for the solution to the metallic rattle coming from the front end of my 04 Berlingo.

After spending hours trying to find the source of the noise in the suspension, this split pin been turned out to be the cause.

Symptoms were, metallic noise (sounded like a few washers on a bit of string getting shaken about), which was only present below 30mph on somewhat rough roads.

Hopefully by bringing this thread back from the dead, someone sees this and solves a rattle!

Cheers,

Geoff
