BMW X5 G05 Transfer Case Service / slipping, jerkiness, shuddering

On today's episode of My Home Garage, we tackle the BMW transfer case problems on many models including the x5. slow speed noise, shuttering, jerkiness, under load acceleration you feel front end jerkiness as it struggles to smoothly transfer the power to the front differential.

Thanks for making this video. I just did this a few weeks ago to my 2019 X5. I too didn't notice the issue at the dealer. They mounted two new front tires on it before we took delivery and not long later we noticed the shuddering. Seems like this is the case for a lot of people! For me, changing the fluid with this procedure resolved the issue by roughly 90%. The shudder was very noticeable before, and now it's almost imperceptible. I too plan to change the oil again after a few thousand miles. Looking forward to hearing how it goes for you.

Been about the same. I really need to get on it hard to even feel anything but it is barely noticeable. All slow speed stuff is gone. Even while turning. I also believe the tires something with the diameter change.

[@loxxrider]

@@MyHomeGarage the tires they put in the back of my car were substantially different in diameter to the old ones on the front. If I recall correctly the diameter was different by 0.75" or so.

@loxxrider do you have the staggers 22 or 21 or the 20s with the sq set up

Why no drain plug BMW!

What size of hose do use to get to the bottom of the case? I cannot get the 5/16” hose down inside the case to extract fluid out? Do you reuse the bolt or replace new one?

[@MyHomeGarage]

I reused bolt the hose was 5mm maybe or less. You really need to bend it to get it down needs to slide down straight in that bump out in the housing.

Dude, thanks for a super informative video. Every detail covered. I have the exact issue with my 2019 X5 . Bought it a month ago, all seemed well. It needed 2 front tyres as they wore unevenly. Last owner probably didn't have alignment done. So I replaced the fronts Only ! rears had some thread left. Big mistake. Transfer case started jerking badly. Rear tyres replaced 2 wks later. Problem still not gone & I've to wait 2 wks for my mechanic (new baby). I'm hoping a fluid change (or 2) and ISTA recalibration will fix the problem like your video. Is it possible I've damaged the Transfer case ?

[@MyHomeGarage]

I personally don’t believe so. I believe when you changed tires. The transfer case calibration got messed up and then it was trying to learn the difference in tread then you changed tires again and it’s trying to further adjust. I’m almost thinking when someone’s changed tires. Adaptations should be reset. Mine is at 45000 kms and the transfer case was acting up. When I bought it and drove it felt nothing then they replaced rear tires and I felt it. Difference from front tires to rear is only 2/32 ( fronts were 7/32 and new rears ones were 9/32).

[@theguyfromdrive4811]

@MyHomeGarage I totally agree with you. It drove fine on the old tyres. Problems started with the front 2 replaced and then the rears compounded the issue. Hard to believe all it needs is nice new fluid and a recalibration. It's so annoying when it slips & jerks. You reckon mild driving for 2 weeks will be ok..? Are the clutches slipping? Will I wreck it before he looks at it?

@@theguyfromdrive4811 hard acceleration and getting on the gas in reverse or forward with wheels locked. I would let it move without using acelleratot

[@theguyfromdrive4811]

@@MyHomeGarage Thanks for the speedy replies. Appreciate it 👍. Great video.

[@MyHomeGarage]

@@theguyfromdrive4811 no worries. Keep us updated. I’m curious. Eventually a rebuild kit will come out. The only real issue is the clutch’s why are people replacing the whole case

[@SwOwW728]

Didn’t you show there was a drain plug at the beginning?

[@MyHomeGarage]

There is no drain plug lol the drain plug and fill are the same.

[@Andrew_Rich]

Good job 👍 What scanner do you use to reset and calibration?

[@MyHomeGarage]

I used autel mx808
