High travel, high clearance & high octane, a streetable adventure LJ story

I'll see if he can get some. 77 ford hp44 i narrowed to waggy width with flat top chevy knuckles and relatively straight arms.

If i remember right good ackermann follows a path from the center of the rear through the balljoint to the tie rod?

Ackermann is a bit like pregnancy. You are or you ain't. But yes, a line starting at the center of the rear axle and extended forward to end at the center of the tie rod attachment point should intersect the center of the kingpin axis.

If he has highly compromised Ackermann, the result will be darty steering with a very non linear response to steering input highly affected by road surface and chassis weight on a tire. As in whichever tire has the most weight on it will impart the most steering output.
 
I tested full articulation some more and found the with the 37" monsters (yes, they're starting to look bigger than they did before) and 14" travel suspension I am sending the tire through the spot welds on the fender.

Cutting out the spot welds will cause the inner-fender to separate from the outer fender. To prevent that I flipped the inner-fender flange from down to up.

So I ordered angled 16ga sheet steel (I ordered extra if anybody else wants to repeat this I can send you a few pieces), cut them down to 10", drilled a bunch of holes in them, put seam sealer on the back being careful to avoid the spot weld holes. I probably went overkill on the spot welds but I wanted to make sure this area didn't fail after all of the other cutting I've done.

Paint sanded away:

New flange cut to length and drilled:

It hurts to be ruining the paint I did last year but it's the only way to progress.

I then mounted a tire and would lift, mark what needed to be cut out, lower, cut, and repeat until I had clearance all the way around the tire. This picture is part way through that process:

Once I was happy with my wheel arch I traced it to a sheet of cardboard and copied it to the other side:

At this point I am very happy that I didn't go with 16" coilovers. I never would have fit them...

Now that’s it’s been a few years, are you still content with the 7 up 7 down travel?? I’m doing 14” 2.0 radflo coilovers this winter with the motobilt rear frame kit which is similar to the rails you made
