Need help! Unknown issue causing excessive tire wear!

Back story: I've been noticing excessive tire wear up front for about a month an a half now. I've taken it to get the alignment done twice since then. First time they said they couldn't get it within specs due to the LCA's adjustments being seized. Ok got it, 16 year old truck from Maryland. Took it to a family friend who is a certified Toyota tech. He replaced the LCAs with OEM and said that he had to do an insane amount of "fabrication" to get it to light up with the existing mounts. (Red flag?). He aligned it and it aligned fine.

I drove it from MD to North Carolina and within 3 weeks noticed it was acting a little sluggish steering. I would steer and there seemed to be a hesitation and even an over correction. I noticed it began to look like my front tires were worn a little more at this point but associated that with the issue I was having before. I have a lifetime alignment package through the Firestone maintenance shop here on base. They worked for 2 hours because "it just wouldn't align". Finally they aligned it (it was past closing) and I drove it to confirm that the sluggish feeling was gone. And it was. Well over the past three weeks I have been noticing my tires wear little by little. I've crawled under the truck to confirm everything was ok, nothing loose.

I tried researching possible causes for excessive front tire wear, called Maxxis to see if the tire was bad. No response. I've been way to busy with no way to take it to a shop or have alternate means of transportation so I've been keeping an eye on it while I save money and research good shops in my area.

This past weekend I had to head back to Maryland to pick up household goods in preparation for my upcoming marriage and trying to furnish my first house. And upon returning a inspected the tires again. And found this.

This is my front passenger side. This is much worse compared to the drivers side (seen below)

And the fronts are MUCH MUCH worse than either back tire. Seen below.

My father has been circulating the pictures around his dealership and they came up with a couple ideas.

1: the alignment shop couldn't align the truck properly and maxed out all the settings.
2: the cant is off, one tire is behind the other.
3: something severely damaged on the front end, they recommended completely rebuilding the front end.
4: bent steering rack.
5: excessive weight in the rear of the truck is ever-so-slightly taking the weight of the front end off the tires causing them to skid.

Now for what I feel and hear:

When parked, if I back out and turn the wheel. There is a pop from under the front. (I found that this symptom has been associated with a worn steering rack bushing)

When accelerating, the FRONT tires squeal when accelerating all the way through 3rd gear, but only occasionally.

When turning (over 30mph) the front tires squeal occasionally.

When hitting a dip in the road, the front tires only will chirp loudly.

When gradually braking to a stop, front tires will again squeal.

What I've replaced thus far:

LCAs , both upper and lower ball joints on both sides, and both inner and outer tie rods on both sides.

Does anyone have any ideas? Or at the least know of a good shop in the eastern North Carolina area?

A bit of important information I accidentally left out. These tires are 5 months old. And have only ~4,000 on them
 
Your lower ball joints are probably going out. ???????

I had a similar issue when mine were past the 10 year mark.

Sounds like possible frame damage... If all the parts have been replaced and different shops have the same issue... If the rear suspension isn't holding up its possible that the front geometry is changing enough to scrub the front tires. Mine sits perfect on an alignment rack, but the front changes depending on road surface and angle you can see the camber go positive at times

Truck has never been in an accident. Only thing I can think of that could even come close to causing frame damage is this (it was caught on video)

Yeah something is seriously fishy with your front suspension. No tire should be doing that at 5,000 miles.

Go get it aligned again, this time at a different shop. Tell them nothing ahead of time, be sure to get the digital printout. Post the printout here.
 
A few questions, the truck tracks straight otherwise? No shimmy? I ask this because unless the non-adjustable castor was somehow severely thrown off- note the vid did not work for me- by an impact, then it could be a driveline issue. You mentioned a clunk noise. I have seen issues in the past with axles binding and causing this, but not on our setup. For sh-ts and giggles, I would take some measurements myself before going back to the alignment shop and spending more loot. Measure (on flat ground) the distance between the fender and the edge of the front tires-back, top, and front. If something is bent it would definitely explain why your friend had such a hard time getting the part to fit. Also, I have seen many shops force alignments. They get the cars to align to the machine specs, but not always true front to rear. In other words, a false alignment. I see it a lot on salvage cars mostly where f/e damage is present. Also measure the shocks position- bottom mount- to the frame and see if its different from side to side? spitballing here...
 
hmm, I would drop the front diff fluid then. I would guess that if there is an issue, then the fluid may reveal metal or other damage inside the case

Truck wanders slightly both left and right, but no shimmy. Smooth ride all the way up to 80mph. Steering wheel feels like there is play in the rack maybe? It's nice and smooth on resistance however it take maybe 5-10 degrees to notice a change in direction.
 
Maybe jack up front and spin a tire and see if the other tire spins with it? Previous owner could have welded spider gears and ADD or some oddball thing like that.

Finally got a print out of it aligned. Shop said it was just "Radial wear of the tires". I took it to another shop and showed them the print out, their mechanics unanimously agreed it was either a bent driver's side lower control arm, or the frame was pushed back on the driver's side.

I didn't hit anything to cause either of those issues. And the lower control arm is so new it still has the sticker on it from Toyota!
