Comanche SS Posted August 4 Author Share Posted August 4 This post is roughly 4 years in the making. Got the TTB crossmember cut out, tacked together and mocked up. It fits wonderfully, some slight adjustments needed, but it couldnt have gone any better really. Before the I-beams were installed, I had purchased and wanted to do TTB, but I didn't have what it takes to do it back then. I put the I beams in instead, and was unhappy with them. Ive spent probably 100+ hours designing this in CAD...it looks simple but it really is not. Getting two items that have a fixed distance, rotation, and yaw squared into a chassis that is only available thru measurements and not in CAD, and then cycling those two items in a suspension cycle to make clearances. and then turning the tires each way and doing the whole process over and over again at various points. Nevertheless it pays off when the very first prototype works this well. It bolts right up, the spacing and clearances are all spot on. Have a perfectly centered track width, WMS is 65'' as factory ford intended. Cycles 8'' uptravel clean, and down travel will be limited by the U joint angles. Should net around 16-18'' usable travel with 4x4 when all said and done. Lots more to come with the design of Double swingset steering, and the control arms, shock mounts etc...

Working on designing the steering as we speak, then control arms and shock mounts Link to comment Share on other sites More sharing options...
Comanche SS Posted August 5 Author Share Posted August 5 Got the control arm mounts started…Will be bolt on with the shock mount and adjustable caster on the radius arms. Link to comment Share on other sites More sharing options...
Comanche SS Posted August 6 Author Share Posted August 6 Had to revise the Control arm mounts for the angle of control arms, and the angle of the beams. Now that the beams are actually under the truck with the crossmember, it’s much easier to get real world dimensions instead of trying to measure thin air and draw in CAD you just hopes itll work.

Comanche SS Posted August 15 Author Share Posted August 15 Steering swingers starting to take shape. Also, received the parts to finish all (14) rod ends that the front suspension and steering take. Link to comment Share on other sites More sharing options...

Comanche SS Posted August 20 Author Share Posted August 20 Some Glamor shots…so relieved this is working, now it’s just a matter of pulling it all apart, welding, painting, and assembling. This has been my biggest design and fabrication challenge to date. Definitely learned a lot along the way. Link to comment Share on other sites More sharing options...

Is there a reason you didn’t go with the regular ttb y link setup? I’m guessing the angles would have been too severe?? Link to comment Share on other sites More sharing options...

Y link steering introduces bump steer, when the inner steering pivot is not in plane with the beam pivot it travels a different arc….same concept with wanting a track bar to be the same length, angle, and plane as your steering in solid axle setups Link to comment Share on other sites More sharing options...
Comanche SS Posted Monday at 03:13 PM Author Share Posted Monday at 03:13 PM Spent a few hours this weekend welding and another few hours sanding, painting and preparing. Hoping to get all this back under the jeep this week, my sinuses are really feeling all the fumes I was breathing this weekend lol Link to comment Share on other sites More sharing options...
