New guy here. I need some help with my 4runner going into 4wd while I'm driving. Original engine was replaced around 300,000. Check engine light on, 4wd light on but flashes with a clicking noise coming from under the front passenger seat. Smooth transition from 2 to 4wd but just before I come to a stop, there is a thump as if a drive shaft is involved. Anyone else experience this?
