Where is this allen head grub screw?
The end of the hub with the six bolts in, there is a grub screw inbetween two of the bolts, or at least there is on mine.
Wayne, you don't touch this, turn the steering full lock and stick your head behind and you will see at the bottom of the rear of the hub a stopper plug (usually has a square head on it) this is the drain plug, Further up the hub (about half way) is another plug (again usually square head) this is the filler plug.
If changing the oil:
1, jack up and remove wheel,
2, remove 'filler plug' first,
3, place container underneath and remove drain plug,
4, let it drain out (leave for a good 10 mins,
5, put in drain plug,
6, pour in EP90 in the filler hole until it starts to come out (now full)
7, refit filler plug.
8, put wheel back on and that is one side done!
John.
