Motor and transmission mount replacement for E60 550

[THaney]

Hi guys,

I was hoping someone might have a resource for me to aid in replacing my mounts on my 550.
I can find videos and write-ups for the V6 but i need one for the V8...


Cheers!

Welcome to the forum.

BMW has never made a V-6 engine.

I will copy the professional instructions from Alldata. They are not easy, and I can't copy the photos easily, sorry.

You'll have to look back at the steps referenced in the "preliminary steps". I will copy them, but you need to put the files together.

Don't forget to use the ISTA computer to reset steering angles sensor, etc......



Oh....you don't have an engine hanger? You don't have a lift? You don't have pole jacks to hold up the subframe? You don't know what an oscillating motor is? You don't have a second person to help, when all this stuff starts falling on your head? You don't have ISTA, to calibrate the steering angle sensor, and reset all the computers you'll piss off?



Sorry man, this IS NOT a DIY job for a newbie. Take the car to a pro.
