T100 4x4 IFS pic/info request (alignment/ torsion bars / ride height) (2 Viewers)

TLDR:
The ride height specs/method outlined in the FSM are not clear to me

Adjusting torsion bars… what’s a good way to set ride height? Droop? Hub to fender rake front/rear?

Can anyone share reference Pics/measurements from underneath front of truck looking straight back??
Distance between LCA and bump stops, LCA angle, hub to fender measurements, etc etc

Looking for stock specs/references/pics


Long story:
I completely removed a 3” trail master bracket lift that the PO installed. Returning the T to factory configuration. I’ve got the lift off and everything bolted back together with new steering parts/ joints and shocks. I’ll be going in for an alignment soon and want to dial in the ride height before I do.

It’s obvious that I have some adjustments to make on the torsion bars because I have a lean and one lower control arm is pitched lower than the other ( not equal)

Without getting too scientific here, what’s a good method for setting the ride height before I go for an alignment?

I’m noticing that the camber adjustment is maxed out on the passenger side (where the LCA is pitched down a bit).. currently camber is close to 0*. This would indicate that I cannot raise this side any more or I would end up with positive camber that I cannot adjust out. Correct?

Driver side the LCA is almost parallel to the ground but still has some camber adjustment left (again sitting at close to 0* now)

Plan of action?
-Raise driver side to be similar hub to fender measurement? Nearly max out the camber adjustment and hope it aligns.

- lower pass side equal to drivers side? .. gain some camber adjustment .. should align fine

I doesn’t seem right that the LCA angle is almost level with ground.. should have slight pitch down? Also truck would stink bug quite a bit in this configuration.

Is there a stinkbug from the factory?... most pics I found show truck pretty level.

Any suggestions ?

Thanks

How to Properly Adjust 1st Gen IFS Torsion Bars to Factory Specs (Via the SM) - YotaTech Forums

86-95 Trucks & 4Runners - How to Properly Adjust 1st Gen IFS Torsion Bars to Factory Specs (Via the SM) - I decided to create this write up to assist with those of us replacing torsion bars, repairing or restoring a front end. There has been a ton of mixed information floating around the 1st Gen...

Theses are from the FSM. It lists different values for loaded and unloaded conditions .. and it’s kinda confusing me on where to start. What does loaded mean ? With gas and passengers ?

I thought it might be easier to get a rough idea on some preliminary settings from ya’ll versus the FSM

I tried doing this once when I replaced my factory torsion bars for +2mm thicker bar for running larger tires. I finally gave up and just took it in for an alignment and asked them to set height as well. I got back perfect set up even with thicker bars. I am still running those thicker bars 25 years later and any time I do an alignment I have them check ride height.

Thanks for the reply I’m gonna try to get it close and have the shop look at it too

Remember to unload front jack it up from frame till both front tires are off ground. Loosen the locking nut and right to raise and left to lower. Hope I remembered that correctly. After any adjustment put it back on ground and bounce the suspension better yet drive it around the block.

Pics I found of a clean stock truck for reference of the LCA angle

Side profile .. looks like there a just a smidge of rake from to rear . Maybe an inch
