Hello all I am new to posting on this forum and am having an issue with the wife's 4runner. When in 4-wheel drive, it feels as though the wheels are grabbing one at a time in no particular order, pulling the truck all over the road sharply side to side. the drivetrain also feels tight or stiff when turning or moving from a stop in say a parking lot. Not really a modern tech guy, just want her to have a safe car as the winter gets worst. Any ideas on what is going on are greatly appreciated. BTW car is an SR5 with v-6 and manual tranny. Thanks again.
