Setting caster & camber at home.

Recently I swapped out my old drums and 66 spindles for a set of 72 discs with stronger spindles. I wanted to check my camber since it looked like I gained a little more between different spindles and springs settling a bit since I did my suspension 2 years ago. In the middle of installing my Street or Track suspension when it hit me how helpful it would be doing my own alignment even though I never did one before. I spent about $125 on a gauge and did a successful alignment. At the time I set camber at 1 3/8*neg camber and 3.5* caster with 1/16" toe in. the car drove great but I did have a bump steer issue going over crests in roads or RR tracks. With the 72 discs, I installed a Baer bumpsteer kit. I didn't make any real attempt at setting bump steer which I plan on doing. I simply installed all the spacers and called it a day. It's a lot better! I plan on doing more on the bump steer later on, just mentioning it now.

So, here are all the photos! I checked camber on both sides before I started, it was just a tick over 1 3/4* neg on both sides. This is the left side.



This is the right side. As you can see, I had them pretty even. I'm pretty lucky as I have a section in my garage where the floor is dead flat.



First part of doing alignment, I had the wheels straight and needed a line on the floor parallel to the wheels. I used this piece of angle aluminum and drew a line on the floor with a pencil.





A little background info is helpful at this point.According to the Ford shop manual a 1/32" shim is worth approximately 1/2* of caster and 1/16" shim on both bolts is worth approximately 1/3* of camber. Armed with that info I went on. Previously my left upper control arm was installed with no shims. I had to add a 1/32" to each bolt on the upper control arm to make camber even with the left side or very close anyway. I ended up with a base line of 1 3/8* neg camber. I was now at 1 3/4* neg camber. I could have left it but I didn't really see a need for that much. I wanted to back down to around 1* neg camber. I also wanted to increase my caster a little bit. Why? because I can! So I set my shim packs up. On the right, 1/32" on both to equalized both sides. Then I added a 1/16" to bolt bolts on both sides to reduce camber a little bit and then added a 1/16" to the leading bolt for a little extra caster. I know, why didn't I just make the leading shim a 1/8" instead of 2, 1/16"? Now I can easily alter caster and camber equally on both sides. Everything is known. If I want a little more caster, just yank out the 1/16" on both sides and replace with 1/8" and caster will be equal. It'll add about 1/2* in my case with my set up.

Right side shim pack.



Left side shim pack.





If you noticed, the end of the gauge is angled at 40*, this gives me 2, 20* angles needed for caster and hence the pencil line on the floor.

This is the left wheel. I turned the wheels 20* to the left and zeroed the caster at 0* and the bubble at the end is level as well.



Now I have turned the left wheel to the right 40*. You'll notice the bubble says 4* caster in the center.



Here's the right side, turned 20* to the right and gauge zeroed.



Now, the wheel turned 40* to the left and caster is 4* according to the bubble.




Here's a picture of the shims installed, right side shown.



I also adjusted the strut on the right side because when I check caster I was about 1/4* off in caster. I'm anal and I could adjust it so I did! It took a very minute adjustment of the rod, maybe 1/16th or less.



Here's the camber on the left side, reading about 1 3/8*, you'll notice 1 side of the bubble is on the 1* mark.



Here's the right side. Pretty good, huh?



Sorry no pictures on setting toe. Between being sick, roto tilling and slugs of beer I set the toe. I was at 5/16" toe in. I set it to 1/8". I had to turn the left sleeve towards the front about 1/16th of a turn and the right side the same amount except to the firewall. OK, so I set this all up in my garage. How does it compare to a laser alignment in a garage? I bet pretty good. Not that I'm a cocky SOB but simply because I put the attention into it. What good is a laser alignment by someone who doesn't give a crap and simply sets each side with in range even though they're at opposite ends of the spectrum? I like the spindle mount gauge with it's 40* angle. It's easy to install, easy to use. I took my TTD's off and put my old steel wheels on because I was too lazy to make an extension to thread on to the spindle threads but I will make one...one day. BTW, I'm not a professional mechanic, just a weekend warrior. It just takes the willingness to try and a couple hours, the results are well worth the effort. IMO a caster camber gauge should be part of your tool box. It'll pay for itself very shortly

I hope you enjoyed my write up. I forgot to mention I used 3 mil black plastic contractor garbage bags folded up for my turn tables, they work great for that! Oh, the car drives very nicely the short bit I drove it.Funny, the car steers very easy even with the 4* caster. Not sure if it's because of the rod ends in place of the tie rods or different angles of the tie rod arms since they're a little lower. Whatever it is, it's easier then when it was set at 3.5*with the stock spindles.
 
Your UCA ......aren't they adjustable ???


Yes they are. Adding more caster that way will very slightly lengthen the control arm. Maybe not enough to be concerned about but anyway, I wanted to keep them short as possible. Adjusting caster that way means dissembling the suspension and you have to do both sides exactly the same. Truthfully I was also some what lazy. It's easy just to stick shims in.

What's great is you do have the option of building caster into the arms. Stock arms do not have any caster at all. I can't say for certain but from doing a lot of reading on these suspensions, they seem to be some what caster limited. It seems like about 2° about the most while keeping camber in check. With these arms you can put some caster in rightoff the bat and add more with shims and or the adjustable struts. Bottom line you end up with a very adjustable suspension.
 
I had a chance to buy this second hand on a Dutch site.
I also has adjustable UCA.

That's a TCP suspension. Your arms have the mounting holes offset 1 inch so you don't need to drilled new ones 1" lower on the body. Make sure you initially adjust both arms exactly the same before you put them on the car then ship which ever side is off so both sides have exactly the same base setting. Then adjust the turnbuckles to set caster and camber to your specs. This way both sides will react the same.
