Maintenance questions

[RayTVR]

Having spent another day removing waxoyl, I thought I'd do some of the maintenance tasks I've been putting off.

So having spent ages trying to figure out how to remove the diff plug, realised I have no idea how to get the oil in or out. Guess I need an 'oil syringe' type device?

Second question is on the TORX bolts that secure the drive-shafts. I have driver market T40 but this definitely doesn't seem the right fit with the bolts - a lot of waggle so I haven't tried to undo yet - anyone confirm if this is the right size?

Just done what I should have done in the first place and checked the 'bolts' Wiki - That does say T45 so maybe I'm just too small..

Thanks for the replies - ordered a 1/2" drive good quality T45 bit, so that hopefully will do the trick..
