I have a question for anyone that can provide some help. I have an '06 F250 PSD and at about 14000 miles it developed a pull to the right after a weekend of driving on dirt roads. The dealer corrected the pull but the steering seemed to wander a bit, it just wasn't right. I then added a 4.5 inch Donahoe lift with 35's and a pull to the left developed. I again had it aligned, but by an independent shop since I wasn't happy with the dealer's initial work. It now drives straight again, but the wandering feeling is even worse. What I've read about alignment basics is that I may have too much negative caster, but that's just a guess. Has anyone else had similar problems? Are they are suggestions for correcting it?

Thanks

 

Front end alignment troubleshooting is like any other variety - a process of eliminating variables. No offense intended, but you increased those variables by adding a lift kit and changing tires while you had front end issues to sort out. I used to do front end alignments for a living (have bad memories of I-beam suspensions still and I was fairly proficient. Steering behavior results from several interactions - front suspension camber, caster and toe are just three of many. I wouldn't venture to guess what might be causing your wandering. This could easily develop into a serious safety issue, is it isn't already. If I were you, I would get your truck to a shop that specializes in 4WD alignment problems. Here is a fairly good summary of caster, camber and toe-in (I've seen a lot worse): http://tinyurl.com/nk6nj
