Hi everyone! I want to flush/change the steering pump fluid on my G 350GD. Can I use Dexron III? Does anyone know the capacity? G-Thanxxxxx!

Yes, you can use a Dexron type fluid. The capacity is less than 1 litre and I would probably go for one of the synthetic formulas (eg Fuchs 5000 SL) which will help prolong the life of the system. Note that here is also a filter element at the bottom of the reservoir.

My technical knowledge on the latter models is limited so not knowing what PAS pump it has and in some of the latter models a fully synthetic based oil has been used which is dark greenish in colour. So if you have oil red in colour, Dextron III should suffice. If the oil is of a different colour then we need to double check on the oil specification. Please furnish your chassis number and note please if your engine has been modified or replaced from another model.

Thanx guys! I changed with Dexron III / filter and now it runs smoother. I still feel an annoying noise/vibration on the steering wheel only when the car is running on the road (when I turn only) might be the wheel bearings? Pistonhead: Will email you my number now. Thanx again

Try turning the steering wheel when stationary. A vibration at mid turn is an indication that the steering box hydraulics are on their way out. If you only have the vibration when moving, then it may indeed be wheel bearings. The front axles has a pair of roller bearings for each wheel and when they begin to wear, you will will find greater lateral movement of the wheel. Try to move each front wheel in and out from the side, by grabbing it at the top and rocking back and forth. If their is any play and if the play disappears when someone is pushing on the brake pedal, you have wheel bearing issues. If the play remains, but does not reduce, when pressing on the brake-pedal, your king-pin bearings may be suspect. Wheel bearing issues are also noticeable as vibration on the front axle and steering when braking at speed.
