I just bought a used Silverado, I was checking things out and noticed both
the rear and front differenial oils are a thick white... In my expierence
this is not normal. However, I decide to post just incase it is some
special GM diff Oil. Any thoughts... my first would be water in there.
I also noticed the cruise contol is no longer working... I checked the
fuse it was not burnt but I changed it anyway... no change... any thoughts?
Yes I checked the oil about 15 minutes after it was driven... I remember
seeing normal differential fluid that has water into it and it turns a
greyish white. The color of my differential fluid is like a thick cream
and extremely white and slick. When I explained in to the dealer he was
perfectly comfortable... he could have easily sold me new diff fluid.
