I have a 2007 Ram 2500 4x4. I purchased it used. It came with 22" rims w 305/45 tires on it. when Im on the highway at 70mph and hit cetain bumps on the road the entire front end begins to shake viciously. The first time I literally thought my wheels were about to come off. I noticed that if i dont immediately hit the brakes it will not stop. I also noticed it wont happen at 65mph or less. It still shakes but its subtle and it stops. Dodge couldnt tell me squat. They said I needed an alignment...duh its from all the severe shaking. Im mechanically inclined and I had a buddy check it to get his opinion. He said it might be the drag link. I bought a new one by moody. Theres definately no visual difference between the two. Any light on the issue will be a blessing...
