Chasing a right pulling vehicle problem

I've been trying to hunt down ways to fix my elusive pulling problem. I initially noticed i had pull when i bought it, but it wasnt bad, so i Ignored.

I added 3 inches of lift. Everything improved a bit, pulling remained and got a bit worse.

So far, i've spend shit loads of time trying to figure out this problem.

My fixes thus far:

New rack and pinion
Energy suspension bushings (R&P, and sway bar)
New inner and outer tie rods, both sides
New upper and lower ball joints
Road force then lug centric balance
Alignment (probably done about 10 times)
upped pressure, lowered pressure, ran door spec too..
New wheel bearings

I've tried everything i can think of to make the annoying problem go away.

New problem (noticed by alignment shop), I've seem to run out of caster.

How can i fix this once and for all.

 

2 wheel alignment or 4?

Most places will only do the front since the rear is solid axle...they have to make sure they're compensating for rear thrust angle and then the front wheels can be within spec, but cross camber is off and it'll pull...just went through that myself.

When you get it aligned, was it always at the same place? What kind of printout did they give you?

 

Yeah, check the rear axle housing, sometimes a big hit can 'alter' a few things, throwing it just slightly out of wack, front can be compensated if not that bad, otherwise you have to get the rear axle running true for it all to work again...

 

If you have 3 inches of lift, you will likely need aftermarket Upper Control Arms to get your caster in specs. This is common with 3" or more lift in tacomas. Did you try cross rotating your tires to see if it changed anything? Does the pull change at all when you are braking?

 

Did you check the calipers? Toyota 4 piston calipers are pretty well known for freezing up and dragging

 

Well at least you basically have a new front end with all those parts you've replaced

 

Check your rear brakes also. Back in my tire shop days, if it pulled to the right, it ususally meant the left rear brake was tighter than the right, and vice versa if it pulls to the left. I know that sounds crazy, but it is true.

 

I know you said the alignment has been adjusted, but was the caster adjustment made? Sometimes the alignment tech will just do toe and camber and call it a day. It sounds ridiculous, but it happens a lot. If the caster is off, one wheel is touching the ground further back than the other one, and will cause a pull.

Sometimes it takes a hot shot alignment guy to do it properly.
