2000 Mercedes Benz ML320 Base 6 Cyl 3.20L
Transmissions & Drivetrains
When I start the vehicle and put it into gear and start going, there is a low grinding noise from underneath.
The Low Range dash light starts flashing when I start the vehicle and then goes out after about 5 - 10 seconds.
Usually if it flashes when you start the vehicle - the low range motor on the back of the transfer case is jameed. Easly repaired by loosening the 3 bolts that hold it on. Take it off and tap it gently with a hammer to release the brushes. Put it back on then see if it works. If it does work keep engaging low range once a week to avoid the brushes getting stuck again.
