Just FYI for those that want to be as close to what BMW calls for as possible: the harmonic dampener E12 bolt has a torque spec of 19 Nm. The fill plug, as stated, at 60 Nm. I just reused old plug since I did not order replacement plug timely. I do these every 30K miles, so I plan to replace the plug at the next change. So far, no leaks, so reusing is certainly an option. Took about 850mL, I would say, so just order 2 bottles.
Thanks for the info. 30k seems really frequent, but I guess it depends how you drive too. Could potentially send in an oil sample to Blackstone for analysis.
Thank you. Just did this yesterday. Easy as pie - almost as easy as an engine oil change. I used a $7 fluid pump from Harbor Freight and it worked great. The tubing comes coiled so has a natural curve that went right to the bottom of the diff housing. I used Red Line 75W-85 GL5 oil and it took about 24 fl oz of that (less than 1qt bottle). I did not replace the plug but cleaned the area well afterwards with brake parts cleaner and will check for leaks later. My 328i has about 70K miles on it and this is the first gear oil change. The oil seemed to be in good condition but was a little cloudy and discolored. I'm glad I changed it. A general point is that FCP are performing this service exactly as I would want them to do it for my car. However, because us DIYers have an ongoing 1:1 relationship with our cars we can afford some leeway in which consumables/tools to use and which parts to replace/reuse.
These guides are always SO GOOD! I just paid £168 labour for this service as I was short on time - someone could save a whole bunch of cash if you did it your self.
When I did this I made an adapter for my suction pump out of a piece of metal brake line. You can bend it as needed to get the most old fluid out of the transfer case or diff.
I have a 2014 435i xDrive, and have had a whirring/grinding noise that’s surely coming from the rear diff after putting it on the lift. Techs suspected that someone put transfer case fluid in their mere and fucked it up (the shit was almost black and smelled burnt). Planning on doing this, hopefully it stops the noise, but it could also be metal shavings from the deteriorating gears as the previous unknown fluid was nowhere near as thick as what’s supposed to be in there.
everything is simple if you have a lift :D but yes i can se myself doing this with jacks. thanks for the info, pls do a video on resealing the rear cover of the diff :D i have slight leaks on my 335i
Great video and explanations! Fluid drag is a big deal in a BMW diff. It will take away wheel horsepower. I wish FCP Euro would carry Amsoil Severe Gear. hint hint.
Great how-to video as always from FCP Euro. Quick question, why would you not just drop the cover and clean out the entire differential? That’s how I’ve always done gear oil changes in the past when there wasn’t a drain plug. It doesn’t look like it’s that hard to access all the bolts for the dif cover on these or a E90/E92. I haven’t gotten under the car yet to inspect but just curious how difficult if would be.
My car has got new stuffing box for differential at the PTO shaft, after the mechanic, changed it makes noise and smells of burnt? Do not know if differential is dead ❓can the destroyer of he screw the nut too hard ❓
no, if you really want to get all the fluid out buy some cheap synthetic 75w90 gl-4 gear oil, put it in the rear diff and drive around with it in for 15 min and then siphon this fluid out and put the OEM in
My vehicle has 180,000 miles on it, never thought I could change the diff fluid until I found this video… Is this something I should do, or avoid it now that the vehicle is at such high mileage?
I'm not FCP Euro but I don't think it's worth the risk. Just as people don't recommend changing transmission fluid at really high mileages if you've never changed it before (180K miles is definitely really high mileage), dif fluid is in the same category. You can potentially do more harm than good by swapping out the fluid. Or if you *really* want to, maybe only change half at once and see how the car responds?
@@ShockwavesFTW yeah I think I’ll stick with not touching it, I’m at 199k now with no issues. Had to replace my radiator today due to a crack/leak.. otherwise the vehicle is doing fine🙏🏽
They say leave unserviceable trannies b/c you can flush the friction material that was suspended in the bad fluid, causing a worn trans to slip. The basic F30’s do not have limited slip or friction material in the differentials. It’s just gears. No risk in changing and it will be better to have clean serviceable lubricant than keep driving on the old worn out stuff. (I usually take about 4 years,on average, to respond on a topic)
ATTENTION F31 WAGON OWNERS, you'll also need a T50, T60, and 13mm socket with 6" extension to remove the subframe reinforcements as one blocks the harmonic dampener. You don't need to completely remove the one blocking the dampener, which would require removing some plastic splash shield with push pins as well. The other one you will but the bolts are very easy to get to and it drops right out. I couldn't find torque specs for any of them.
@@bathanmark I used the Liqui Moly 75W90 kit from FCP Euro for the front and rear differentials and BMW oil for the transfer case, since I had a bottle already. I did them at the same time.
Hi! Thanks for the valuable info! Can i use a GL-5 oil, instead of a GL-4? (both 75w85). I've been searching and found sources claiming that you shouldn't use GL-5 on manual gearboxes since the additives for EP (extreme pressure) may damage copper and copper (syncromesh rings). But when you are using them on a differencial, the GL-5 is actually welcome, due it's EP additives
Hi Gareth, just bought a used 2014 F30 320d with only 20k miles on it. Still far below your recommendation of 50k miles to change the diff oil. However, since this stuff oxidises with time, should I replace it now considering it’s over 8 years old now?
Do you have a video for Diesel Exhaust Fluid replacement on a 2016 328d? I understand BMW stealerships drain old DEF out and replace with new fluid, but I don’t know if that’s really true, or if it’s necessary.
@randy's Retired DEF fluid is all made the same for diesels (they are meant for emissions). It burns off as you drive the vehicle so nothing needs to be flushed out. You just pour more in when it says it's running out. It is the blue cap next to where you top off the fuel tank when getting gas. Just be careful not to spill when pouring in. You can pick up DEF fluid from Autozone or O'Reilys (the mixture is all the same regardless of brand).
@@marrroquinnn Thanks for the response. BMW always did a “flush and fill” when I was getting my car serviced by them. I’ve started doing the services myself and wondered how one did the flush portion.
If I get one of those transfer pumps, I could use it for transmission fluid, differential fluid, steering fluid, maybe something else. (Not brake fluid). BUT, how do you clean out the old fluid after use, so you don’t contaminate?
No it wouldn’t hurt. The only time it would hurt a car to do a fluid change is if you did a trans flush and used what mechanics have that port at the radiator and pull vacuum on the trans fluid and then adds fluid at the same time. They don’t change the trans filter so all that dirty trans fluid gets everywhere. Will end up messing up a trans. Especially if it’s worn.
Lifetime of any part is the day after warranty ends. For example if the engineer says the transmission is lifetime and sealed with a 100,000 mile warranty the 100,000 miles is its lifetime. So I’ve been told
Sounds like you need to get on it asap! As long as it is still operating properly, no harm is in servicing it now, and continuing to service it regularly.
I have a BMW 2011 328i x drive it wobbles in the rear like the rim is bent, it worsen when riding @ around 20 to 30 mph the higher speeds its lesson. Could you tell me what is the problem? It's not a bent rim I replaced the rear rim, still the same results.

Any value to tipping up the front end to send the fluid to the back of the diff. Maybe get a little more out?
no, if you really want to get all the fluid out buy some cheap synthetic 75w90 gl-4 gear oil, put it in the rear diff and drive around with it in for 15 min and then siphon this fluid out and put the OEM in

So BMW is right. Lifetime fluid. These guys are wasting their time with this service. If you have a diff issue new fluid won’t help you.
Front and rear diffs take different oils?
Do these fluid expire? I noticed a date on my bottle ordered from fcp thanks

Hi Anindya, congratulations on the new buy. While it would be a bit premature in mileage, you are certainly going to cause no harm in doing it early.

Anybody using Redline 50104 75w85 on front and rear diffs?
Would it hurt anything if you were at like 90K-100K miles when you did this?
No it wouldn’t hurt.

They don’t change the trans filter so all that dirty trans fluid gets everywhere. Will end up messing up a trans. Especially if it’s worn.
Anyone know why the front diff takes G2 and rear takes G1?
BMW specification clearly states the oil there is a lifetime fill hence no drain plug ;).
Lifetime of any part is the day after warranty ends. For example if the engineer says the transmission is lifetime and sealed with a 100,000 mile warranty the 100,000 miles is its lifetime. So I’ve been told

Thats the same diff fluid I need on my 335i 2015?
Think so
my 2014 328d xdrive has 176k miles. is it too late to change the fluid? Could it potentially cause issues?
As long as the differential is not showing any signs of bad wear or failure, you would be okay with changing it out.
Did you change the oil in the end? Was it because of the diff noise. Mine at 133k miles and noise from diff, thinking of changing oil
@youonlyliveonce5576 So you are going to change the oil after it starts making noise? Ship has sailed for it not having internal damage.
I have a BMW 2011 328i x drive it wobbles in the rear like the rim is bent, it worsen when riding @ around 20 to 30 mph the higher speeds its lesson. Could you tell me what is the problem? It's not a bent rim I replaced the rear rim, still the same results.

Unless you're paper thin, you may at least need to jack up the car. It can for sure be done without a lift though.
