The BMW G30 520d owner inquired about shaking and vibration when driving over 25 miles (40 km) per hour.
Well... this requires a test drive and inspection, so we can't determine what needs to be done just through a phone consultation
The owner made an appointment and came in
We took it for a test drive first. It really shakes..
Strange reaction.. It's not common for it to shake like this at low speeds..
So we lifted the car.
Huh?! What?!
Wow.. This is scary.
The BMW 520d's rear flexible joint (also known as the "briquette") has burst to the point where the threads are popping out ㅠㅠ
To think we test drove it like this.. We thought it was just simple driving vibration.. This is brutal
You may know this, but if this bursts, the propeller shaft can hit all sorts of parts underneath, potentially damaging the car to the point of being a total loss..
Thankfully, we didn't push it hard during the test drive because we felt uneasy ;;
The nut was caught on the yoke, keeping it in place..
I don't have a religion, but.. Thank God.
Upon detailed inspection.. Huh?!
There's a record of the flexible joint being replaced. But.. it's a Chinese product ;;
As I always say when working, it's not good to use Chinese products for this part on all BMW models..
Not only is the durability poor, but it's also too hard and often causes damage to the yoke differential
Not all Chinese products are bad. But we need to be selective. Some parts are okay to use, while others should be avoided..

When we explained the inspection results to the 520d owner, they confirmed that they had indeed had repairs done before. About a year ago!?
So we initially advised them to go back to the place that did the repairs and ask for a re-repair. But ;; the owner said they felt uneasy and asked us to do it instead.. Even though it's a duplicate investment ㅠㅠ
Well, if that's what they want, we'll do it.
We always keep BMW flexible joints in stock
It's one of the most common repairs we do.. So it's not difficult~
However, the bolts and nuts are all damaged, so we need to order genuine parts. It can't be done right away and will take about a day
It's really rare to see something like this.. Haha
BMW owners, if you've seen this?! Consider it a consumable part and
Usually, the flexible joint replacement time is around 62,000 miles (100,000 km)..
Or if there are any cracks or abnormal symptoms upon visual inspection, immediate replacement is recommended!
The inspection isn't too difficult. When you get your annual work done, like changing engine oil, they lift the car, right?! Ask them to check it at that time~
We usually do it anyway, but many places don't, so
