Vibration @ 55mph and above w/creek sounds at all speeds.

Insist the tech rides with you. Start driving, tell him when it happens/under what circumstances and then have him drive that same stretch of road.

 

You really need to be working with an MD Alignment shop. A couple great ones have been mentioned. These people are on another level from any dealership or truck stop. They’ll get your truck straightened out. At the rate you’re going, you’ll be broke AND still have a shaking truck.

A tail light less than 50%? Boy, that's a new one, and I don't know what QVR is, but sounds like another fleecing. You know dear, you are talking to drivers, for the most part, that vibrations were just part of the job. I drove an R model Mack that shook so bad, it would pop out of gear. When confronting the boss, he said, yeah, yeah, the truck always rides rougher on a Monday than a Friday. There was some truth to that. But all trucks shook, except Peterbilts, and was something you just lived with. Today, that is unacceptable, and you have to go faster than 60, and many times, todays mechanics don't know much more than you, you'll get it right, and I'd like to say that should be that, but again, it doesn't work that way. Repairs on a used truck can do you in. Not the biggies, so much, but that tail light, that would pizz me off.

 

It sounds like you have a pretty good idea what’s going, especially for only being in this 6-1/2yrs. And, 3 trucks? Holy smokes! You’ve seen and dealt with quite a bit, then. I admire your courage and tenacity to get after the O/O thing. Keep your chin up.

 

I may be the TTRs wet blanket, and I never want to thwart someones initiative, but with all honesty, get out now. If you are already in debt, it will be 1 step forward and 2 back from here on in. Most here know what you are trying to do, peddle your way through it, and most, me included, have been through exactly that. I don't mean to be rude in any way, but you don't know enough about trucks or have the resources to have a truck today. The only thing that saved me, and others, is we did our own work. You are NOT unique, and some say as many as 50% of O/Os, some say 90%, throw in the towel every year. With so many great company trucking jobs out there, I say swallow the pride, rid yourself of that headache and let the boss worry about repairs. Best of luck, get rid of the truck. With your experience driving, a company would hire you in a minute, and wipe your debt clean in 6 months, and spend Xmas with the family. It's not a matter of "giving up", there's no shame in trying.
