Re: can i align truck myself
Not cool and definitely not necessary. We are just discussing car alignments here.
Strong language sure, more for the shock and to make someone think though.
To put this in perspective, my day job involve me being in charge of machining of parts with values in the millions of dollars. 1 part alone can be valued at over 2 million dollars, and I might be over seeing several at one time. Tolerances of these parts can be very close, as close as .0001" sometimes even less when we get into light bands.
I have access to some of the best inspection equipment available, including laser inspection equipment. We have proven time and time again laser has limitations, and although it gives you nice clean numbers it is not always gospel and the data must be looked at carefully. It is a great tool sure.
We don't machine a single part using the laser systems to determine size. For that we use good old fashion inspection equipment, not tape measures very often but not far from it at times either. The laser is only used for final verification of features we already know are correct using "tape measures". When you get to .0001" tolerances a laser is worthless.
My point is it naive to say a laser will always be better than a string/tape measure method. Some mechanics can, others will fail depending who is on the string/tape measure.
The original question of can you do an alignment at home is YES and you CAN get just as good of job, and in some cases better (some worse).
In no way do I claim to be an expert, but I have done a fair amount of research, college level suspension classes, and hands on. I didn't climb out from under a rock last week, in fact I was around syty's 14 years before the poster in question joined this site, and cars way before that.
