[Powerstrokediesel199]

just replaced the ring and pinion gear and all the bearing on my 05 f350 and put it all back together and when engaged into 4wd it pulls relly hard when driving down the road from left to right kind of jerking the wheel outa my hand, and when you hit a bumb it's worse. Need help anything would be appreciated

4HI on dry black top normal jerks the poop out of the wheel in a turn. But I must ask that you define "when you hit a bump it's worse". Bump like a speed bump? Bump like one tire only? Big bumps? Little bumps?

Look, if your back lash it right, and it ain't making funny noises (been there, done that with my 67 Mustang), the ring and pinion is fine.
