X5 Transfer Case Actuator Motor Gear Replacement
I finally uploaded the DIY video for repairing the transfer case actuator with a new gear. I completed the repair in December 2015 and we have had zero issues since!
The BMW service centers will tell you that the entire transfer case needs to be replaced at a cost of over $4,000 simply because they do not replace the actuator motor or the plastic gear inside it. We also did a drain and fill of the transfer case with fresh BMW fluid after replacing the gear. Hope this helps someone get back on the road! https://www.youtube.com/watch?v=UR7Vv5SQvDc Good luck! |
Great video

Re Brand.
On ebay, there are some sellers, but who do you guys use? In other words, who sells the best quality plastic gear? Brand Name? |
A vendor sells Aluminum gear, interesting...

I've also seen a Kevlar reinforced gear and a carbon fiber gear I believe

I got the carbon/kevlar reinforced nylon via Amazon, as well. Seems to be working fine, been in there well over 25k miles .....

I would be concerned with the aluminum gear causing wear on the worm screw. Then you would need to replace the entire actuator.

I was thinking the same thing; I'm not sure what the screw is made of, but I'd rather it destroy a plastic gear after seven or so years of use, and just replace that. Aluminum is usually a soft metal, maybe someone who has tried one can chime in after a few years of use to let us know how the actuator has stood up over time with an aluminum gear. |
Is this repair a recommended procedure, even if you don't have any
dash lights? I ask because I am nearing 100K miles. No dash lights at all. I have a 2004 X5 4.4i |
