Hi,
before you repair the Gear Box check first the Bearings of the Drive Motors. To 95% There will be an destroyd Bearing on the Gear Box Side.
Taking out the complete Drive Unit is easiest way. Disconnect Cables / Hand- and Footbrake. Then relaese all Screws of the Gear Box and take in two M16 x 600mm stell sticks where you can shift the Drive Unit off. Thats the way.
