Leaf springs are a pain to get right on a rock crawler but when you set them up the right way leaf springs will flex and perform brilliantly off road.

I had a great uncle that built quite a few off-road vehicles mostly for farm work, but whenever he set up leafspring suspension, he would stack a bunch of iron weight plates on the front of the vehicle to simulate transmission and engine weight, if the vehicle was not so equipped.

@ryanreaves1203 2 күн бұрын

I had really good luck running 7" long shackles on my k5 blazer because it allows it to flex really well but also allows the leaf spring to be closer to the frame giving it a lower ride height because the shackle ends up sitting flatter.

Building a frame from scratch would have been a far easier, safer and quicker, and not to mention the cost, chopping up three vehicles to bodge one together not a brite move in my books, so far I cant see you winning the challenge at the moment. So I am not sure whether to vote for you yet.

I'm gonna say negative on all 3 of those. Building a frame from scratch would be cool, but its not cheaper, not faster, and definitely not easier. The rear will however be a custom ladder bar frame out back. Stay tuned for that.

@MrSnowlver 2 күн бұрын

Ideally you want your shackle to be vertical when fully loaded and at ride height. Ff you remove weight it will look like it did on the toyota. If it leans too much with the top toward front, the spring will bind. Springs get longer when they compress

I might install a mini winch at the back of my shop to pull vehicles in. Might be worth doing something like this at your place; one in each corner probably. The small ones are about $100 a piece and can be bolted to the floor with anchor bolts. (Red Head) Is a good anchor.

Little tips next time you try to put weight on the front (for settling down the leaf) Take a jack under your axle, pass a chain underneath it then go wrap around a crossmember or frame... Pump the jack and it will collapse your suspension!👍

Probably mentioned already but you could do a front shackle so the axle moves away from the foot well when the spring compresses.

@muddyWW 3 күн бұрын

Why didn't you use the springs from the Dodge? The axle you replaced was a D60 so it should of bolted right in. They were longer which gives a little more suspension travel, the springs already was able to support the weight of the engine and you could always pull or add leaves (from the Toyota maybe) to adjust ride comfort/suspension travel/ ride height. The body looks high enough that you probably don't need a ton of lift and like you said you could always drop the front mount down a little and add longer shackles ( I think the sliders would be better and custom mount them like the Comanche). Those Toyota leafs look too short and too much arched for good suspension travel

@Garth2011 3 күн бұрын

@williamherring5441 3 күн бұрын

One guess is the Toyota springs might be shorter which gives up travel, but they are softer and might flex better with the diesel.

@monoeyemulisha7203 2 күн бұрын

When it comes to King Pin 60s about 10% of the parts are interchangeable. Ford is an oddball, GM and Dodge use a hand full of the same parts and don't even bring up the international or Jeep 60s. The Yota has a GM 60, the hubs are the giveaway. He cant use the factory dodge spring setup because the axle out of the Yota has been narrowed. you can tell this by the length of the long tube on the axle. Its shorter than the the one the Dodge 60 (GM 60s are wider than the Dodge 60). As for the spring, Having a shorter length spring makes it easier to move the axle forward. The factory dodge springs were to long and put the tire into the body. You can compensate for soft springs by adding to the spring pack (which would be a good idea) or get a custom set made.

@muddyWW 2 күн бұрын

@@monoeyemulisha7203 In the video at first the shackle doesn't line up with the driver side frame rail, after a cutaway and the next clip the shackles are mounted to both frame rails, the front mounts also look to line up with frame rails. So either that means the spring perch (other side is cast in the diff) has not been moved on the Toyota axle or they did some "magical stuff" that wasn't filmed or shown. The factory Dodge 60 and a factory GM 60 spring perches only are a 1/2" different from each other. Moving the axle forward with the shorter springs does make sense, but they are using the Dodge factory location for the spring shackles and you can see in the video that the front hangers are away from the factory location on the Dodge. So their plan to move the axle forward using the shorter springs doesn't pan out. You can take the Dodge springs and re-drill the center pin location letting you move the axle forward. But that might not be needed as you can re-drill the holes in the spring perches (if they aren't all ready there) and move the axle forward that way. Or even make some offset plates that move the axle forward and back. And before anyone says that the spring will crack at a new drilled center hole has either never done it or did it wrong. I've re-drilled 2 sets so far and never had them crack at the hole, I've had them crack at the spring eye.

@Garth2011 3 күн бұрын

Lots is involved in this kind of work. I'd like to know how the measurements are made when the two frame halves were mated to keep left and right rails exactly the same position to prevent crab tracking or thrust angle, wheelbase etc. Same with the changes in the leaf spring mounts...those also have to be front to back in the exact place for wheelbase dimensions and side to side for "thrust angle" for lack of a better term. I guess in the next few videos that will be explained and shown. Would love to see this all finished and placed on a 4 wheel alignment machine !!

You're overthinking how a machine made for crawling over boulders at 1 mph needs to be laser straight. We are getting things really straight for sure but it could be off by inches and you'd probably never notice.
