This motor is used to engage the low-range gearset in the transfer case on your ML-Class.

If this motor fails, you will no longer be able to engage the low-range gearset, or even worse, be unable to re-engage the hi-range gearset.

Fortunately, Euromotiv offers this brand new transfer case motor for your ML-Class so you can get it back on the road, driving as well as it did when it was new.
