Powerman5K Posted February 7, 2023 Share Posted February 7, 2023 I have a friend that is the county's Auto Mechanic teacher for our trade school. He has agreed to align my truck for me and use it as a teaching point for his students. Only problem is, his computer data base for alignment specs don't go that far back. Does anyone know or can point me to the correct alignment specifications for a 2WD 1980 F100? I already know I'm screwed and won't be able to adjust my camber. But I'd like to be able to get all the others dialed in as best as I can. Thanks in advance. Link to comment Share on other sites More sharing options...

85lebaront2 Posted February 7, 2023 Share Posted February 7, 2023 I found it in the Documentation section of the site. Thanks! A couple of items, first be sure he checks ride height at both ends as the caster varies with ride height at both front and rear. Second be sure your radius arm bushings are in good shape as they also affect caster. Camber varies with front ride height, rear doesn't have much effect on it.

I just changed them. Camber is crazy positive but can't be fixed due to me having King Pins. Everyone on here keeps saying the same thing "You have to bend your I beams." I've called every shop and restoration place in the DC area and no one will touch them. I just have to live with the camber and rotate tires like heck!

AmericanSavage Posted February 8, 2023 Share Posted February 8, 2023 Does anyone have thoughts about these at Summit? It would save folks a lot of money if they worked well! And so many line up shops are refusing to touch anything "old" anymore. https://www.summitracing.com/parts/tnh-3300 Link to comment Share on other sites More sharing options...

And so many line up shops are refusing to touch anything "old" anymore. https://www.summitracing.com/parts/tnh-3300 Toe can be done with a pretty simple rig. First something to scribe a line in the tread while spinning the wheel. Set the truck back on the ground, move it back then forward for the suspension to equalize. Use a couple of cheap squares that will reach halfway or a little more up the tires, a 2X4 and two C-clamps to determine the difference front to back of the tires. I aligned or BSA camp 1987 F250 with twin traction beams using this for toe-in and two blocks we trued on a shaper + a level for setting camber (LF front was cambered in badly at the top, eccentric bushing was 180° out.

Rembrant Posted February 8, 2023 Share Posted February 8, 2023 Here's an alignment report from my 1984 F150 2wd. Keep in mind it had ball joints and not kingpins, but should be the same overall more or less. At the time of this alignment, the truck had all new ball joints and factory original concentric 0 degree bushings. Link to comment Share on other sites More sharing options...

The problem with the king pin axles is there is no camber adjustment provision other than bending the beams. If it is way positive, I would check two things, the actual ride height and the inner pivots for the I-beams. Same if it is way negative, except you can add spacers or replace the springs.

mat in tn Posted February 9, 2023 Share Posted February 9, 2023 The problem with the king pin axles is there is no camber adjustment provision other than bending the beams.

Same if it is way negative, except you can add spacers or replace the springs. in looking for new springs for my 81 f250 camper special I was surprised to find the same springs listed for f100 through f250 from most available sources. yet I did find also that there are sources who sell the same spring for 80-96 while a few list the 80-81 as a different spring. I'm wondering now whether you have a spring spec'd for a different model holding it too high either due to coil rate or static height differences. a "one size fits all" mistake. taller /stiffer spring will add camber every time!
