pro-trac alignment

We only use Hunter machines too. I saw this Pro-Trac on the internet and kinda giggled. I have see these type before where you just hang a laser over the side of the tire. They would get you in the ball park, that was about it.

 

If it did balance to zero why use the centramatics?
I swear by the tape weights and a well calibrated balencer , and or a on vechicle spin balencer.
Now if the vibration is in the rear of the seat or at the floor look else were, drive shaft or rear tires.

 

Seriously a 6 degree shim?? If you needed that must of a castor change you have a bent axle or the tech/ machine was hosed! A 2 degree castor wedge is about a 1/2 inch thick. I think they took you up to 6 degrees castor is what you mean.

When you check castor the most important part is the difference between the 2 sides. It's referred to as cross castor. Ideally you want the difference to be zero. I will let as much as .05 degrees difference go but after that it has to be fixed.

 

A SIX DEGREE!?
WTF?
The bigest i have ever seen is a 4 Degree or 4x4 is what i have herd them called.
But if you havent been in a wreck or anything like that chances are that the axle shifted and or you rear axles are out. Also tire wear from a previous condition will make a truck pull and you need to flip the one tire around to neutralize the pull after all adjustments are done

 

In Houston

 

Pro-Trac = a joke. Every star and moon must be in line for this contraption to work as advertised, and yes, I have used it. In fact, when I took over the Service Dept I no longer performed alignments because the Pro-Trac system was basically worthless and impossible to "prove" results to a customer.

 

Hey I know this is a old tread but In Houston I used these guy http://qualitymultiserv.com with good results . They check the truck with vis check for free and tell you what's wrong with it. Prices were reasonable . I haven't been there in a while cause I don't go to houston anymore hope this helps .

 

Is Pro-Trac the same thing as MD Alignment?

 

Yes
