I have been using this technique for well over 20 years and I thought I would share it with everyone. I just happen to need to do a little adjustment to my Cab so snapped some pics. Here are the details on how to do an alignment at home for FREE.
The list of tools you will need-
Duct Tape (or something equally as strong)
Angle Finder ($5 from Harbor Freight)
2- Tape Measurers
17mm Socket/ Ratchet
Your favorite music to jam to
Before you get started it is important to note- The alignment must be performed in this order. They can be skipped if your not planning to set that adjustment, but Toe must always be set last.
1. Set the ride height (ride height effects camber and toe)
2. Set the Camber setting (camber effects toe)
3. Set the Toe setting
How to set Camber
I didn't set mine this time around so I will rough some pics together to give you an idea.
First, make sure the car is as close to level as possible.
Take your square and the angle finder and place it flat on the wheel perpendicular to the ground. You may need a piece of metal long enough to span across the entire wheel if the wheel isn't flat. This measurement is your actual camber. I am sitting at around 1 degree.
Calculate what you need to add or subtract to hit your goal. Jack up the car. Set it on jack stands. Remove the wheels. Slap the angle finder on the wheel mounting face of the rotor. Make note of what the finder reads at this point. Remember that with the wheels off the ground this will not be your true camber. You just need to add or subtract to the number you have when the wheels are off the ground. Loosen the strut bolts adjust to perfection.
How to set Toe
First you need to jack up each side, spin the tire and draw a line around the it. Pen, pencil, chalk.. doesn't matter. And it doesn't matter where, just somewhere close to the center. Make it as straight as possible. My tires are new enough, I could still see the mold lines to use as a guild. I also take this time to wipe off all the loose dirt off the tread.
To properly set toe the car must sit on the ground. For you folks that have your cars stance "on the ground" this will be a pain but it can still be done. I have found that if you set it on a piece of wood it makes it a lot easier to turn the steering wheel back and forth. You will be doing that quite bit until you get the hang of it.
Run two tapes on the car until they come out the other side. About 6ft will do. One in front and one in back of the front tire.
Place a decent size piece of tape on the end of the measuring tape. I like to put it on the 5 or 6 inch mark that way the tape "tongue" doesnt interfere with the tire. Align the tape with the marks you made on the tire. Also make sure that when the tape measurer is stretched tight it doesn't interfere with anything under the car. This will affect your measurements.
IMPORTANT NOTE TO REMEMBER- It is not the actual number we are after here. We are looking to compare the front to the rear measurement.
Measure what you got. I had almost a 1/4" of toe out. This is what I get for playing with my ride height.
Take you 22mm wrench and loosen the tie rod jam nut. The hexed area just to the right is what you will use to adjust your toe. If you are way off you will want to do a little adjusting from both sides. Do note that the tie rods are not reverse tread. They are both lefty loosy/righty tighty.
As you are adjusting, make sure the rack boots dont get all twisted.
Before you turn the wheels back and forth, make sure you kick the tapes out of the way so they dont end up under the wood and get ruined.
I usually like to give mine a little toe in. The reason is when the car lowers down under load, the car will naturally want to toe out. Here is what I ended up with this time.
Can this little bit make a difference? Yep and a big one at that. Now my Cab doesn't want to dart around when it rides over ruts or cracks in the road.
Setting the Steering Wheel Straight.
Through a combination of tie rode adjustments and wheel relocation you can get your wheel to be dead on.
Note that the more you practice at this, the easier it is to replicate next time.
