Front end issues
 

I have a '98 Dakota 4WD Supercab with a 318 and auto. My issue is when I apply the brakes while driving, the truck jerks hard to the right. If I let off the brakes, the truck dives back to the left, but not quite as hard. I've replaced both front axles, both upper ball joints, and had the transaxle checked. I've also removed the front drive shaft, all to no avail. Any help would be greatly appreciated.
