Front differential on my 2017 X5 I used Redline 75w85 like you did. For the rear differential I used the same 75w85, I could have use Redline 75w90 also. For the transfer case I used Redline MT-LV 70w75, you can also use Rein Automotive TF0870.
For the rear there’s actually one alternative in 70w80 gl-5 bmw recommended specification from mopar believe it or not, here’s video about it: th-cam.com/video/dEUObIuK3Fw/w-d-xo.html
Front should be fine I don’t think you should have problem with the rear as well should be fine as well, reason for bmw using 70w80 is for fuel efficiency which I dk t think you’ll see much if any decrease in fuel economy, remember this is an open diff it’s very hard to mess it up, there’s no friction plates in there all you need is lube and 75w90 is close enough lube is lube 😉
@@MotorsportInspired Hi, thank you for the great explanation. So it is better to go for 75w90 for longevity since it is a thicker oil? Does climate take into consideration?
Technically yes, main reason why bmw specified different weight oil for front and back is for fuel economy improvements. if you run same oil front and back you’re going to be totally 👍 fine plenty people have done it before.
They do this all the time even now with their motor oil. Their new requirements of the Valonline xl-iii 5w30 for my 2010 35d has the same part number as their 0w40 euro full synthetic. Sneaky sneaky sneaky…

You did a great job. I have a 2016 BMW X5 diesel xdrive35d ..going to follow your example. I appreciate your video.
Thank you 🙏

How is your X5 running with the MT-LV? I used the Ravenol transfer case fluid.
@@Simple_TH-cam i didn't notice anything
@@Ashley_van_SchooneveldIs the Mt-lv still working well in the transfer case?
@@Dom-e92I would also like to know this
Great job. You deserve more subs.
I ended up filling the front & rear diffs with Liqui Moly 75w90 GL4/5, haven't noticed any difference from the factory fluid
I'm planning on diff change - I figured Liqui Moly for the front, but good to know for the rear as well as it's significantly less expensive.
Rear calls for 70w80 which only alternative is this ebay.us/zhoRpV
from mopar I used with good results as well affordable as well compared to oe bmw.
Any issues so far with using liqui Moly 75w90 GL4/5 for both front & rear differential?
Can I use 75W90 Fully Synthetic Hypoid Gear Oil (1 Liter) - Liqui Moly LM22090 for the front and rear diff on my 2016 X5 F15 non performance?
Does this apply also to the g05 bmw x5 ?
That pump design is genius. Do you know where to get that valve?
Thanks, I had a spare valve of a transfer pump that was broken I used it here, but you an buy similar one amzn.to/3NgboWC
Are those oils synthetic or regular?
Some GM diffs have a much lower fill spec, 1 5/8in below.
This gm is synthetic
I’m going to trying the valvoline 75w90 for front and back on x5 3.5d ….what u think 🤔? Thanks

@@MotorsportInspired thanks a lots for the response ! Great job 👏

Hello i have one question is good to use the same oil for the front and rear differential?
Technically yes, main reason why bmw specified different weight oil for front and back is for fuel economy improvements. if you run same oil front and back you’re going to be totally 👍 fine plenty people have done it before.
@@MotorsportInspired great thanks! 😊
👍🎄
How much rear differential fluid you changed out?
1 liter
Shouldn’t the car be level for this procedure to put correct amount of oil?

Yes very sneaky another way for them making extra money 💰 on people that just don’t know any better.
