Now that we have that squared away we can burn (fully weld) the spring perches in to the axle. I opted to leave everything tacked until the very end then I finish welded everything at once.
Now more measuring and shock placement.
Now that we've cycled the leaf spring we know how much wheel...
Now you can see that as the suspension cycles upward the pinion angle also rotates upwards. The u joint needs to stay within 4 degrees of alignment between the line coming into it and the line going upwards that the 3rd member is on. Although the difference was only 3 degrees in this first...
Unfortunately this entire process involves a lot of putting parts on, taking them right back off for days at a time to get everything built correctly and to ensure accuracy.
In saying that, I did all of this from a wheelchair for 21 straight days to make the BOO BAR POKER RUN. It's hard work...
I had to make my own shackles too. You can obviously buy everything but I like to save money and I enjoy working with metal so I opted to make my own. I essentially semi-copied a known companies design and theirs run for $350. I made my own for $20 and my time.
These are my first gen MexicoJoe...
After all the new geometry is tacked in to the frame rails we need to set the pinion angle of the 3rd member and driveline. Toyota uses a double cardon joint in the driveshaft between the front and rear shafts. Because of this you want the u joint and line angle to be straight. Set the pinion...
You have to! Plus, the colors on the fish pop so hard right out of the water vs 20 minutes later. It's incredible if you look at the detail on a Halibut right when you pull it out vs 1 hour later.
First: I had to cut all of the stock Toyota suspension geometry off of the truck.
Second: Start measuring and marking for Long Travel suspension geometry. There are plenty of write ups on how to go about calculating and measuring the new geometry. I can link my Tacoma World page below for...
I had just completed the work on the back of the truck the night before we left for the Boo Bar Poker Run 2020. Here is a detailed guideline to how I made the rear set up.
