Important safety issue:
Many people have work done to their cars and trust the mechanics blindly, this includes me (and i should know better). a week back i had the rear A-arm (IRS) bushes changed on my type 182 and didn't bother to check the work as i thought everythign would be in order. yesterday i took the 182 out for a drive, anyhow, long story,... on the way home i heard a VERY odd sound from the left of my car, enough to scare me into dropping my speed to 10km/h. as i was only 1km from home i decided to check once i get home.
when i got home i started to check the car, i found the rear centre nut/crown had opened and the nut was so loose i ended up removing it with my bare hands!! now had this come off on the road on a moving car you can imagine what would have happened.
reason for this is that when the mechanics did the work, he didn't insert a cotter pin into the crown. now remember that a cotter pin is a specific piece but if you do not have one handy you CAN use a nail even. anything will work as long as it stops the nut from opening.
I urge you all to go check your cotter pins immediately or you're asking for trouble.
OEM Cotter Pins
Wheel nut as i found it (almost off)
2 twists with my hand and off it came
local cotter pin installed in rear left hub as the OEM one couldn't fit in the crown
OEM cotter pin installed in rear right hub (though not perfectly)
