just read the maintenance guide on this. i assume there is no drain plug hence the need to take the cover off.
can't be a***d with all that and getting covered in smelly hypiod, any reason why i shouldn't just suck out the oil through the filler with my trusty 12v engine oil change pump and refill? actually i'd top it up first so i know how much leaked out and to give it a flush.
-
For the sake of ten bolts, surely better to remove the cover... also gives the opportunity to inspect the mechanicals...
Once removed, you can file away the casing to a depth of about 4mm at the centre bottom bolt to act as a sump drain using the bolt as a sump plug :y
-
yes but its unplug 2 abs sensors, 2 x 18mm bolts, 9x 15mm bolts, get covered in oil, remove cover, clean up mating services, apply sticky sealant to hands, fit cover, torque up 2 x 18 mm bolts to 90nm, apply threadlock to 9 x 15mms and torque up to 60nm, replug abs sensors....
quite possibly it would leak afterwards unless i am scrupulous with the cleaning...
i think she should be grateful i am changing her 'oil for life', not expect an inspection of her private bits as well. or a new hole fitting.

Halfajobbob ;D
Seriously, if you can't be bothered to remove the cover, which incidentally probably leaks already..., then why bother to jack it up at all :-\

The differential is a tight fit in its case, so you're unlikely to suck out much of the oil. Although it's probably almost empty: I got almost a litre in mine when I 'topped it up'

I beleve you can 'install' a drain plug by drilling though a specific bolt hole....
may be wrong, but worth a search.

Bottom right... I suggested judicious use of a file, Master suggests very careful drilling, :y
-
What is the OOF recommended interval for this procedure?
Clearly the VX interval is - never.
-
Master suggests 50k :-\
-
And on the list it goes... 20k overdue by that reckoning ;D
-
Its really quite a straight forward job ,and worrying how little oil does come out when you remove cover plate as most can be drained down carefully once face plate is loose.
Quite a satisfying job when you compare how much of the 1ltr new oil you get in compared to what was removed so best advise is do the job properly and rest assured in the knowledge your diff is correctly filled.
-
Yes drilling through the correct bolt hole will 'create' a drain which can be plugged with the bolt easily enough.
The 50k is for LSD diffs, the reason being that the friction modifiers fail over time and they start to judder then wear accelerates quickly, the standard diff should be ok for much longer (but its cheap and easy to do)

Exactly how I did it. (Listens for shouts of derision), and in both cases got the required amount of new oil in with no problem. :y

i won't. i'll simply drive it up my ramps. :y
-
I just carefully drilled mine out after a good blast to get the oil nice and hot, the flow of oil should bring out any swarf, just go through nice and slow :y
-
Having just read through the maintenance guide, I'm not 100% clear on why you need to slacken the 2 Diff support bolts. Do they allow you access to one or more of the cover bolts? :-\

At the risk of incurring the wrath of the good Dr Gollum, a couple of questions:
Did you drill this out in situ (ie without removing the cover plate)?
Which bolt hole did you use for the drain plug and what diameter did you drill out to?
Reason I ask is that mine (miraculously) doesn't leak so I don't see the advantage of removing the cover if i don't have to.
-
Without removing the end support bolts the diff will not drop down far enough to be able to get onto all of the cover plate bolts...ensure diff is supported on jack though.
Cant answer drilling question though ..couldn't see the benefit as it was quite simple removing cover plate and you are sure the internals are all ok with a quick view with plate removed.

Ggrrrr...
Just kidding :-P
If you read the guide, there's a picture which should answer all your questions...
Personally I would leave well alone if dry, and file a notch diagonally up and left from the bottom right hand bolt.. If drilling it would be the same course but be mindful of the thread...
-
I drilled up on an angle from the bottom of the bolt hole diagonally upwards to the back of the bolt hole using a 6mm drill bit wrapped with insulation tape to help protect the threads, this was on the bottom most bolt.
