Rachels 1999 4runner, limited has developed an issue with the 4wd. Sometimes either from a stop or after just shifting into 4WD the rear PS tire is not spinning and then you feel a big bump and it drives fine.
I verified this in the snow. When it occurred, the truck would move to the right because the tire was stuck.
In the 20 minutes I drove it around, it happened twice with the button (4HI) and I was not able to make it happen when downshifting to 4 lo. Doesn't mean it won't happen, just didn't happen in the 20 minutes I was trying it.
To reproduce it, I would stop the truck and push the button (4 HI) the problem would occur and the status (4WD) lights would blink. When it jumped and unlocked the tire, the lights stopped blinking and showed I was in 4WD.
Rachel said it happened (she thinks) to her when she started up from a stop at a red light.
If the rear output shaft froze while engaging, would one tire spin and the other freeze? Not sure what else could do it.
Any thoughts on stuff to try.
