Hey did I hear correctly at the end that those are M8 bolts and to only set them to 52nm?
Yes that's right pal :-)
Hi mate, great video, really helped me with my own seal replacement! I just have a question, how easily did the flange go back into the diff for you? I just banged mine in using my palm and it felt too easy considering it was quite difficult for me to get out. Hoping it is okay though, is there any tell that it is not? Cheers
Glad it helped you buddy. The flange went in really easily if I re-used the old circlip (just left it on) . Had to give it a full on beating when I tried a new circlip. Spoke to a mechanic who advised no benefit to using a new circlip.. So you got it right & that level of resistance is spot on 👌👍👍
@@FixItWithJon In that case I may need to unbolt the flange and try to get it back in further because I replaced the C-clip. The dust cover just doesn't appear to be sitting as snug to the diff as it should be. When you used the new circlip, did you just hit it with a rubber ended hammer until it moved? Cheers for responding - It's good to chat with someone experienced
@@cadeausten6659 Ah - I see, yes it's probably not locater in the diff soundly in that case. It should be pretty clear when you re-inspect it. I ended up using a 5lb club hammer and it still took ages to get the thing in.. (rubber mallet was useless) The other side I just kept the old circlip on and it was fine - just pressed home with my hand. When I spoke to the mechanic he said the circlip doesn't really do a lot - the lateral force from the road wheels keeps them in place in any case, the circlip is really only there for best practise. Hope that helps?
Hi Jonathan, thank you very much for sharing this video. I have the same oil leaking on my E61 520D touring of 2009 with 177hp and AT6 gearbox, I do not know if my rear differential is the same as yours. Your car is a automatic gearbox or manual?
Hi William, mine is an automatic, although I'm not sure that makes any difference to the rear diff option they fit.. There seem to be 2 types - 1 with a drain plug and 1 without. As you can see - mine is the one without.. Hope that helps?
@@FixItWithJon Hi Jonathan, thanks a lot for your reply. Mine is also without drain plug, I think I have the same rear differential as yours. At the moment, the leaking problem seems not so important, but, it needs to be fixed. Your video and your information are quite useful for me, many thanks again!!!
i know this is an old video, but do you have a link to correct oil seals?
Hi Chris, sorry for delay - have been away - here you go: 173536454634 Hope that helps?
@@FixItWithJon thanks, got them for £5 each
wheres differential bearing location?
Depends which one you mean - the side driveshaft bearings are just inside the openings behind the seals. The propshaft bearing is obviously at the equivalent location on the input end.
Hi, thank you to post this procedure. Do you need to remove the rear wheel and the colar nut on the shaft to be able to remove the output shaft after releasing the torx bolts on the drive flange?
Hiya, no - I didn't. It is tight and you do have to jiggle it about quite a bit, but it will move out of the way without removing the wheel and collar nut :-)
@@FixItWithJon Hi, thank you your answer. Finally I figured out: the wheel should be raised a bit by jack and the the output shaft can be removed easily. To press the seal use the output flange: put the seal to the flange after lubed the seal's sealing surface. Insert the flange into its space and press it by hand until you feel resistance. Try to rotate it to check the teeth are in good connection. If it is OK, teeth position is good than punch the flange to the right depth. The flange will press the seal evenly into its space. Do not apply too much force, it is not needed. Be carefull with the depth: if the seal pressed inside up to the lock ring of the bearing than the seal will cover the oiling hole in the shaft's housing which will prevent the right oiling of the assembly. I found the right position is when the dust neck of the seal is in line with the shaft"s housing outer edge. Remove the shaft with a pry bar time to time to check the depth of the seal.
@@mihalym.6876 Thanks so much for your detailled reply. So glad that you were able to get it done ok. I didn't realise that lifting the wheel gives you more play on getting the flange out - that is a really useful tip. Re. driving it in - top tip not to replace the circlip on the shaft or it will be a nightmare with the extra resistance. Personally, if I had to do it again, I would buy a socket that has almost the same OD as the seal to drive it in (very gently). I put mine just under the outer edge of the diff - I know what you mean, if you over-drive it, it obscures the oil pipe and that scuppers the diff very quickly..
@@mihalym.6876 So - one of the sides has started leaking - must have not got it in right. I replaced it and modified my method based on your comment. It was definitely 100% easier to drive in square just using the output flange. But - I think I drove it in too deep (about 2mm deep) as it is leaking worse now. But... I found this:
www.newtis.info/tisv2/a/en/e61-520d-tou/repair-manuals/33-rear-axle-rear-wheel-drive-guide/33-11-transmission-housing-with-lid/FRlBu0c
Which suggests BMW say it should be installed 19.5mm deep - that can't be right?! If it was that deep, it would definitely obscure the oil feed hole.
I am going to do it again (!) and will video the process. I think it should be very slightly proud of the surface (like 0.5mm) and I think that I maybe didn't lube the sealing surface sufficiently.
@@FixItWithJon did you sort the leak out again?
How deep did you end up putting the seal in the end?
Do you have a part number mate? Thanks
Hi buddy - sure it is 173536454634
Hi do you have to drain the oil out of the diff? Thanks
No need - it's fine. There will be a very slight dribble of oil, that's all.
On this topic: Some diffs don't have a drain plug & you have to drain with a pump connected to a hose placed deep inside the topup hole..
I need a translator for my American ears.
Lol Mike all you need to do is replace "shop" or "supplier" with "Store" and any reference to "car crash" with "auto wreck"; "motorway" with "freeway" and you're all set & good to go ;-)
