Today it was snowy and at some point traction ctrl kicked in, showing the little vehicle light on the dash. There after the light went off. About 10 seconds after and I noticed a very short, very slight pull to the right, as if my steering was odd. It went away almost immediately.
About 30 seconds after this I got a jolt, like I had a missfire or as if the breaks had been slammed on and released instantly. It happened twice, the second time about a minute later.
Soon as I got home, connected the scanner, nothing. Well there was stuff but not related to this, so different questions for these...
My best guess is that the traction ctrl is applying brake when it should not be, perhaps slightly, leading to the strange steering sensation and then the sudden jolt applied hard?
Any suggestions where to start on tracking this down?
I discovered under hard acceleration that the 4WD light would come on which implies oil temperature too high. I have now discovered that my real differential is leaking oil. I cannot tell if it is leaking from the side-gear or the back gasket or both.
Could this explain the jolts?
