When my Dak is at speeds of 63-66 MPH it vibrates really bad. If you want to know what I mean, drive on the highway and drive on the shoulder on the bumps they put on the road to warn you you are near the ditch. And it is like that until I speed up to over 70 or until I slow down. It's only on the passenger side in the front. One idea I did have was that a few days ago I replaced the half-axle and realized that the Brake Knuckle was missing one of the bolts that holds in the brake in place, it was stripped out and my grandpa put in a standard bolt that had a smooth space on it deep enough for the brake to move around the same that it would on the standard bolt used there.

 

Could be a loose half shaft, tie rod, idler arm, shock, ball joint, tire out of balance.

 

Check the factory service manual and troubleshoot it. How exactly do you know it is from the front right?

Typically tire balance vibrations are present at all speeds if I remember right. A bad U-joint would have the potential to create vibrations only in certain speed zones.

 

Have you checked your lug nuts? God knows that's happened to me a few times. I put the wheel on and forgot to tighten the lug nuts before I cleaned everything up. The next day, the vibration was in sane. I thought the wheel was coming off.

 

mine vibs between 45-55 in the floor, pretty sure its the driveshaft though. Where does yours vib at (steering wheel, floor, etc.)?

Sounds like the same thing as my bad driver side ball joint.

 

thanks guys. I tightened the lug nuts cuz a couple were loose and it didn't do it. I'll have to go through that guide Crazy gave me when I get back. I'm flying down to California for a week. I had a couple friends die this week and its kinda thrown me off focusing on the truck. thanks again for the help guys

 

A couple? ****. Sorry, man.

 

Yeah, crazy stuff happened. He shot her, then himself =(
I've been working on my truck to distract me but my fam is making me go on this stupid vacation to Cali. Oh well, the truck will get done in time, haha.
