Power steering effort

Help!, Is there any way to alter the amount of power steering boost on my new G500? The new G's have much harder steering at low speeds. It bothers my wifes shoulder when she runs it around town. It is so bad that she wants to trade trucks and drive my G320. I do not want that to happen, so I need some help

I am willing to persue even fairly involved procedures on this one. The truck is worth less than I owe thanks to a flooded market. I am stuck with it. If I can correct this problem, at least I can continue to drive my oldie but goody

Thanks in Advance

Brent

I don't know why it would be different (I'm not saying it isn't different, I just don't know why).
First thought is possibly the tires or tire pressures are different?

The change that occurred was the addition of a tilt steering column. The older style interior had a fixed column. The new G's are adjustable.

I am really wondering if there is an adjustment of any sort that affects the pumps output to the steering. Maybe a valve that can be altered to increase boost. Do you have any technical knowledge of the workings of this system?

Thanks for any help

G-Man, funny you mention this. I don't know if you noticed this when you test drove the ML way back when, but it's much the same way. All the ones I've driven were the same. Everyone who drives my truck usually lunges nearly straight forward out of my driveway a large amount and then frantically turns the wheel and overcompensates to avoid the curb on the other side of the street. Then they go wow, that's weird steering. It eases up with a little bit of speed and is excellent on the road, but very counter-intuitive in a parking lot or driveway. I'd be willing to make the sacrifice and swap my ML with your G for a while so you can investigate this further.

the pulley change would just increase the volume but not the pressure. belts would be too big

m's are rack and pinion and g's still use the worm/ball style box. totally different animals.
ask your wife to let the g roll a little while turning the steering wheel. ( i told mine she'd kill the tie rods if she was NOT moving while turning the wheel )

i guess the fatter/ wider tires cause more effort than the 320. two more cylinders and the electronic crap probably add a few more 100#.

there might be a spring to increase the system pressure ,but i don't know if this would be incorperated into the check valve for hitting the stops.

the 99 f250 had hydrolic brakes that ran off the power steering pump. when the abs kicked in the steering wheel locked. pucker factor would run high, so i would disconnect the abs fuse when 4-wheelin.

tell your dealer that the steering effort is to high and see if he will replace the pump. you might get one with a tighter tolerances and thus higher pressure. if that does not help you might add a pressure relief vavle in the return line? or thicker fluid after the warrenty go's.

like you boat.
