ECS also has a DIY where you remove the entire subframe from the car with everything attached except the parking brakes, driveshaft, etc... Someone said it was easier to do it that way. The BMW repair procedures. You can find it in ISTA. |

I would recommend the ECS install method. However, I suggest not removing the driveshaft from the differential, and instead unbolting it from the back of the transmission. These bolts are easily accessible, don't need any thread locking agent, and don't require any special tools to properly torque. You can easily slide the front differential bracket off the front of the driveshaft. You also do not need to remove the parking brake cables as long as you are careful not to lower the subframe too far.

Awesome photos. Really helps see the process. So from what I gather you lowered the subframe. Then braced the diff and removed the front mounting plate sliding it forward down the driveshaft. Then pushed out all the bushings and put it back on. Where'd you get that scissor jack? |

is the main reason you need to lower the subframe because you can't get to the bolt on the far right due to the gas tank?
Wondering if using e torx wrenches would give you that space? https://www.homedepot.com/p/GEARWREN...B&gclsrc=aw.ds |

Just finished up swapping out mine. Figured I'd share some notes to help others.
-The chassis brace that you need to remove uses a T60. Only place I know of on the car with this bolt. It's also right by the lifting point so annoying, so undo them before jacking up the car. - The transmission brace you need to remove. It uses a T55. - remove the driveshaft from the damper, leave the damper connected to the trans. Driveshaft toque spec is 55nm + 90°. - subframe service bolt(x4): https://www.ecstuning.com/b-genuine-...w/07147426660/ - subframe service bolt washer(x4): https://www.ecstuning.com/b-genuine-...h/31336776760/ - replacement subframe bolts(x4): https://www.fcpeuro.com/products/bmw...-9-33302284642 - replacement driveshaft bolts(x3): https://www.fcpeuro.com/products/bmw...s3-26117527475 - Replacement driveshaft nut(x3): https://www.fcpeuro.com/products/bmw...ut-26127536563 - eTorx ratchet wrenches: https://www.homedepot.com/p/GEARWREN...204616566-_-N& Helpful in not having from drop the subframe down as far to get around the fuel tank.

I’m interpreting this as you used the method of removing the driveshaft from the trans but not from the dif to remove it more easily? Is the “bushing” you’re referring to the guibo? And Is the driveshaft torque spec you have listed for the 3 bushing/guido bolts? Very helpful post, but I could use some clarity on those points. |

For those who tackled this job DIY or even brought it to a shop, did you "renew" every single bolt, screw and nut that you removed? I was wondering if all the hardware is actually one time use or you can reuse. Any advice on this ?
