DIY Failure Caused Exploded Rear Diff MK7.5 Golf R #vw #shorts

The owner of this car made a very expensive mistake. Let me be clear I am NOT picking on them. This is a weird setup and ive seen professional technicians make that same mistake. But here is what happens when you drive 9,000 miles with no fluid in the rear diff! #humblemechanic #diy

It lasted for 9000 miles with no fluid. That's incredible.

I will not touch anything without watching a YouTuber do it first. Laugh if you want to, but watching over someone's shoulder that is tearing apart the same s*** you're about to encounter is incredibly helpful and reassuring with a tremendous confidence boost if you've never done it before.

Poor man, feel sorry for the owner. Sometimes it's easy to make mistake. I work a lot on my car or family and neighbors etc. don't have a workshop it's more like weekend, driveway, hobby stuff. One time, while resolving some electrical issues, I connected battery terminals wrong way, don't ask me how. Thought that the ecu was definitely cooked, dashboard went black, nothing on it. After surviving minor heart attack, reconnected battery and luckily everything came back.

But wasn’t he confused when the haldex was still full after draining??

[Jotomoz]

Don't close the drain yet so you know you got the right fill plug

Had a buddy change the engine oil in his 5 speed escort. He mentioned it only took 2.5 quarts. We were at work and I wasn't paying that much attention when he told me. 5 or 6 weeks later he tells me his clutch went out and locked up the front wheels. Had it towed to a shop and had the clutch replaced. A few months later he brought it over to change the oil at my house. He climbs under and goes to work. I peak under and see red oil draining into the pan. It all finally made sense. I'm amazed that a new clutch was all it took to get it back on the road. I think that was the last time he ever attempted to change his own oil again.

I'm a mechanic so this might come off as kinda arrogant. But when he went to go fill the haldex and it was full already you think you would have noticed. Also I imagine the haldex does not take that much fluid so you would think man wonder why so much stinky gear lube is coming out of my haldex.

If you work on your own car invest in a factory manual!!! They are not expensive! I have been saying that for years

[stephenwelsh]

I done this when I was an apprentice in VW around 16 Years ago. VW released a Tpi about it not long after. Easily done

[BOBHLDRMN]

It's needles to Every good home mechanic that I know takes their time with their stuff and does it RIGHT ... !

[ThomasOfGilead]

Honestly good for the dude for working on his own stuff. It can be extremely rewarding or extremely humbling, and both are great learning experiences. I hope this doesn't turn him away from doing stuff in the future, just keep on keeping on brother

When I was working on my Honda Ridgeline I meant to drain some transmission fluid if you had accidentally overfilled it when topping it off, I pulled the drain plug in the bottom of the transmission and it as it turns out I actually pulled the drain plug for the transfer case.. I trip to the store for some gear oil later and I was able to fix it and ended up with new transfer case fluid. Lessons were learned that day, definitely be absolutely certain you have the right drain plug because they put those things right next to each other not too many vehicles in places where they should not be

I would not say "in his defense, " because there are multiple issues here. Many people have mentioned to start filling fluid with the drain plug out. I myself do that every time on a diff or haldex just to flush out whatever is left at the bottom, if there is any sort of metal.

What most people are leaving out is what the Haldex actually is, which is the mechanism for controlling the torque split between the front and rear axles. It sits between the driveshaft and the rear differential. Removing a drain plug right under an axle is almost always a differential (might be some cases where it isn't but i doubt it). That's just negligence at that point, not taking the time to educate yourself if you're going to do it yourself.

As with anything DIY, if you dont know what to do or aren't 100% sure or conpentent in yourself, DON'T GUESS. YouTube is a fabulous resource when it comes to vehicle maintenance and a lot of general maintenance items are covered on almost every consumer car, exceptions being low production vehicles like supercars and high end luxury cars.

Wish i had the humble mechanic as my car guy. The dude kicks ass🤘

[Crptonc]

Personally this is actually good news, shows how well built / strong it is - zero oil and it lasted 9k miles ! Wow that’s impressive it’s like a Honda made V-Tec diff 😂

[danhg]

Toyota used to have separate trans and diff cavities in their automatics (much like VW 01Ms) and many shops on install would forget to fill the diff side of the automatic transaxle.

[leftcoastdrifter]

My favorite customers work on their own cars, too. 😊

[aldairhernandez]

What a goat man it always helps to have somone who really know what there doing like this man here🔥🔥

[robertcast]

Thanks to you guy that’s why I watch your videos just to make sure. Thanks pal

[janmartin]

I always use the workshop manual when working on procedures such as this! Haynes!
