Hi all,

The GMC alignment kit is now complete and will be tested by a number of users at the upcoming unofficial southern Oregon non-rally (SOOR) in a couple of weeks. I published the 30 page illustrated guide on my web site (http://jerrywork.com) today. Go to the GMC Motorcoach page and click on "- Everything you need to know about aligning your GMC to run straight and true". The file posted is release version 0.5 beta. Once I get feedback from these SOOR users, and any comments/corrections you care to email to me, I will produce a final release 1.0. The file is in .pdf format. I left it about 8mb in size for best image quality and will likely reduce the file size for the official release version.

The guide is in several sections:

The first talks about why it is hard for most commercial alignment shops to properly align our GMC motorcoaches.

The second talks about the different components an owner needs to do their own alignment measurement and my objectives for this kit.

The third section is a detailed nine step process that takes about 30 minutes by which any GMC owner can do an accurate measurement of front and rear ride height, front camber, caster, toe and centering of the steering box, plus rear camber and frame parallelism on all four bogie wheels.

The forth section gives detailed instructions on how to build or acquire all the components for an alignment measurement kit like this one.

My hope is that through the largess of this forum group you will help each GMC club acquire this important safety kit and make it available to all GMC club members. You can use my guide to build a kit and donate to your GMC club, or help them acquire a kit from me if you prefer. I don't care how the clubs get the kit, I just want to make sure each club has a kit available. Our GMCs were noted for their fine and easy drive style when new, but many current owners experience a far less comfortable or safe driving coach. From what I have learned, I believe improper alignment of the front and rear may be the basic reason these coaches handle far less well than most. And, improper procedure by commercial alignment shops may well be the root cause issue.

The .pdf file you download contains copyrighted, restricted use material. You are free to use the information for any non-commercial purpose yourself, and may post the file or links to the file (wait for release 1.0) on any GMC club, vendor or member website, but you cannot use the materials for any commercial purpose without my expressed written consent to do so. Thanks. I look forward to your feedback.
