I feel the MN 2.5 diesel is a little overgeared and I'd like to change the final drive ratios from 3.917:1 to 4.3:1, as used in the 3.5L petrol ML. I'm well aware that the engine will rev higher for the same speed and it may affect the fuel economy, that doesn't worry me greatly. Does anyone know if the 4.3 gears from an ML will go into a 2013 MN 2.5 diesel?
ok what about putting ml 4.1s into a manual mn with 3.9s in it, if I change the diffs over how much difference will this make, would have to help running 33inch tyres I would think ? sure there would be a formula hey ? didn't SRB do this to his clubby??
You could swap the entire front diff assembly out of a V6 ML into your car and run a vacuum line to the actuator to keep it locked in. Or takes the gears out and get a diff specialist to install the gears into your housing and do away with the actuator setup.
