This is a great build! I plan on using a very similar suspension setup for my future build (as in "I'm stealing your idea....mostly!")! How is this this guy turning out weight wise?
Thanks Mark! Please steal away, that's why we post our builds here!
I don't know if I had posted this before but I had originally planned on using a pair of the fiberglass mono-leaf springs that I pulled off a Ford Ranger project I had going for this build. After getting the axle unwrapped and set on stands with the springs it just wasn't looking like a good option; the springs are almost 48" eye to eye and I would have had to run them as spring-under to keep the altitude in check and it just seemed like a hack kind of solution compared to the rest of the work I was doing.
After the mono-leaf I committed to air suspension and imagined running a 3 link or 4 link setup so I bought some poly bushings and sleeves to fab links. Again, I should have thought the whole plan through
. I mocked up how upper and lower links would have to be positioned and didn't like the loss of ground clearance I would have had to live with.
After more brainstorming I sketched up the wishbone link that you see. I ran the poly bushings at the axle to take some of the harshness out of the connection, but mostly because I had them and didn't want to let them go to waste haha. The Johnny Joint at the frame connection was a piece I had in the shop from a set of long arms that I never started for my Bronco II so I figured it was PLENTY strong for this application. The panhard bar was a "some assembly required" part from an online supplier that I setup to be as long and horizontal as possible.
The adjustability front-to-rear at the Johnny Joint and side-to-side with the panhard bar let me tune the suspension to center it left and right plus center the wheel in the fender wells. In the future I think I'll be upsizing the wheel and tire combo to match my Tacoma but that's on the back burner!
If you have any questions on the setup please ask, I'm glad to help!
