After all that work he puts on a brand new actuator... says a lot about replacing the plastic gear

[@jhfl1881]

Nothing wrong with the gear as well. He could have tried to find a stripped gear to show why one should replace it.

[@twilliams3904]

No is watching it🤣🤣🤣🤣

[@ron8566]

Nice work - I learned alot. Rather than fitting a replacement gear I would spend the $80-$128 for a new actuator motor and case with new mounting bolts. Good stuff nonetheless. Thank you!!!

[@luisvaladez8486]

Pull the motor remove the gear assembly from the main motor assembly..then turn the gear 180 degrees. You're good to go for another 100k miles. Nothing to buy

[@edorofish]

The old switcharoo! We caught you!

[@Le3icester]

i just fixed mine i just rotated the Gear 180 degrees works like new lol

[@virgilmobile1]

Replaced my plastic gear as shown.The replacement was out of round.This caused binding as the motor turned when bench testing the acuator before installing it.Replaced the plastic gear again and shimmed the motor mount so it would turn smoothly.

[@aircooledshack7154]

So if replacing the gear is the fix why fit a whole new unit at the end?

[@lakomacias5160]

Im doing 1 next monday...how much should I charge...thanks...you videos are su helpful...new subscriber here😅

[@FraxinusExelsior]

Great instructions!

[@Davenz]

Ours is wearing out in 50,000 kms. We had 4 new Bridgestone tyres that match the door jam label, with exception of speed rating, so rotational difference should not be a factor. BUT, the trifecta of lights comes on every couple of days, goes off after a couple of engine restarts. Any clues why that would be??

[@ibdewett5032]

hey seen video wery good but why put new on if yuo have fix the old one on video
does it need to be ajustet after

[@markobrien4005]

Rebuilds the actuator motor, obviously struggling to get the cover to stay down when peening it, next shot is a obviously new actuator motor being installed. Nice idea but peening aluminum is not easy and to try and get a good seal on that cover would be difficult.

[@Judah28]

Do you have one for bmw 2 series gran tourer

[@askershabdeen3376]

Good job

[@not_virtuality]

I just did this job without removing anything

[@randyerwin2109]

I thank it is great showning the video

[@glenglene8473]

what is the symptom if the gear broke?

[@harrylong9781]

It's $800 for the part online. $ $1,500 dealer

[@Amirsabha419]

Why you installed brand new one?

[@user-hk2zg4ch2b]

BE sure to buy the BRASS upgraded gear

[@user-md7sc5ny1f]

Just a bit of warning. The bolt head holding the Transfer Case is 18mm (not standard!)(The bolt is M12, and 18mm heads are not recommended for designs by standards. However BMW tried and succeeded to make it very difficult and expensive to repair). I have a large key set and the 18mm hex key is not included.
It is torqued really hard and with the inevitable rust it is very hard to take off. You need an impact rated swivel+impact gun since the design of the bracket is Terrible!!. And yes, you need a car lift, and possible a second person to help. And more, a welding torch was needed to heat up de bolt so it can be taken out. Some say that the bolt is locktited in place so when you try without heating it it breaks and then you really need to go to the dealer!
The plate holding the white plastic gear must be sealed against the actuator case rim after the new gear is mounted inside. Otherwise water and salt will go in and ruin your actuator in not so much time!
The car also expects after the repair to have a program run on a BMW OBD programmer, to have an adjustment done before driving. Another program must be run on OBD when you replace the TC fluid.
So yes, these can be done with a specialized BMW OBD scanner tool only not with any tool.

[@carlosfletes1730]

Ese que está instalando, está completamente nuevo XD

[@mikecamacho1934]

Can get a whole new one for under $100

[@imbohica3933]

Wtf man after all that you just put in a new motor

[@tonybainbridge2607]

Why pull the trans mount, no need. Guess he's paid by the hour.

[@supercrack27]

Jajajajajajaja después de tantas historia va y lo cambia por uno nuevo 😂😂😂

[@robwilliamson5950]

No point in replacing old with new or rotating 180 degrees these will fail again at about 100k. Replace the original gear with a carbon fibre one available on eBay. Wtf BMW made a plastic/nylon gear operated by a steel worm is beyond comprehension. 🥶

[@HeadshooterGTAS]

a plastic gear what a stupid idea bmw

[@blackdick74]

This makes no sense why put a new one after all of that?
