is there enough movement to pry the back plate open to drain the oil without removing the diff hangar? is it a silicone seal as per front diff - why did they not fit a drain in the bottom ?!? the front diff - fair enough - but the back - now im looking at it is making me scratch my head a bit....

 

We sucked it out with special device and it worked fine. Didn't work with front.

 

I syfioned mine out m8 and the pwr steering fluid, it took a while tho if thats any help.

 

easy when i got down to it - gave it a good wipe out and resealed, filled with nice new fully syn castrol TAF-X 75W90

just needed a trolley jack under to take the weight of the diff when it dropped down .

 

be giving that a go meself then! if i can get under the bleeding thing first

 

whole job took less than an hour - you need a t50 torx bit to undo the diff plate though - i ended up taking the bit out of the socket to get it in the gap at the top and use a open ended spanner on it - there is not much room there.
