2002 G500 steering problem
I owned since 3 years now my dream truck! a 2002 mbusa G500. I love that truck. I've been very lucky so far, I never had problems with the truck. the G has now 125000 miles on it. It's my first post on this forum, even if I read a lot on it! it is so helpful!
But since around 2 weeks the steering became suddenly VERY heavy. I know the G steering is always heavy, but now it is more than heavy!
I looked at the power steering fluid, and it seems ok.
I have new tie rods, new steering damper, new tires on it...
when driving it, it feels like if the diff is lock, but without any lights in the cluster or on the dash switch pack. I have no check engine light or abs light, nothing.
during my 3 years ownership of the truck, I NEVER had to lock any differential. I use the truck 95% on pavement. I never go offraod.
I tried today to lock and unlock the center diff to see if the problem would go away. I pressed the center diff button and the yellow light came on the dash and on the button itself. the red light never came on, even when trying to turn the steer side to side riding slowly on grass.
so my question is: is it possible the the differential is now lock, even if I have no light or any other signal at all?
If yes, what would be the part to change or to look at?
Is it a known problem with the G500?
every advice are welcome!
thank you
I'm a little obsessive with maintenance but it keeps you from the trouble and expense of repairs and replacements.
after all, oil & grease lose viscosity over time, dust & various internal particles build up in the lubricants too. All making things drag.
