I have a 2008 4.7 Dakota, it's pretty high mileage with 225,000. I've had it for about 2 months and have noticed a problem when going around bends, when going around bends the steering wheel shakes and feels like it tries to pull back to going straight. It's gotten bad enough that it makes it hard to keep I'm my lane unless I'm tightly holding to wheel with 2 hands. I've replaced both the front wheel bearing. I have replaced the tie rods which I thought might be the problem but when I jacked the truck up and try to shake the wheel there is no play and looking at tie rid ends while moving the wheel it appears to be very solid. Any help to figure out what might be wrong is appreciated.

 

A binding/loose Lower Intermediate Steering Shaft joint when it's under a steering-wheel "load"? It's the steering shaft between the firewall and the rack, which has a U-joint that is known to cause weird steering/binding issues if the U-joint in the shaft develops play. There have been previous posts/topics here on the subject in the past, worth a search.

 

Regardless of what the light shows, make sure 4WD is disengaged.
