Car pulls right

[chargd72]

Ok guys.  I'm stuck on this one.  My car has been pulling right for a long time now.  Here is what I've done since the beginning.  Rebuilt lower control arms and added new bushings, new adjustable SPC upper control arms, new upper and lower ball joints, new tie rods, new Helwig sway bar, new torsion bars, new ridetech adjustable shocks, new Dr diff front brake kit that came with new hubs and bearings.  After all these upgrades, I got new wheels with brand new tires, I aligned the car and sure enough it still pulls right.  Pulls even harder upon braking.  I have access to an alignment rack so I can go as many times as I need.  Any direction would be helpful.

Did it pull to the right before all of the mods as well?

It was pretty much all over the place before.  Alignment was WAY off and about every bushing on the entire front end was toast.

 i would check the wheel base on both sides, the rear end my be off, they make shims to correct that.

Power steering? Jack the front wheels clear of the ground and start the motor to see if it wants to "self-steer".

Another good thought.  I do have a slight leak in my power steering system.  I could be losing cylinder pressure in the box.

Yep.  I was wondering if my leaf bushings could be the culprit.  They are pretty bad as well.  Might as well replace those too.

I have a similar issue pulling left. everything is new and the front end is aligned.

read about repositioning the power steering valve to help compensate.

Throw it on the rack and set it up for a 4 wheel and check the rear angles. Also check thrust angle. If everything else is in check and the powersteering is centered, set the caster on the left side .3 degrees less then the right. For example: if the right side is at 5.0 degrees, then set the left at 4.7.

Swap front wheels/tires left to right and see if it pulls.

Swapped out completely new wheels and rubber with same effect.

Started it with the wheels up this weekend and no self steer.  Seems like the steering wheel had even resistance turning in both directions.

I'm going to swap out all leaf spring bushings and see if that helps.

How about putting it back on the rack before you go throwing parts at it? What were all of the measurements that you took and what were your final adjustments? If you set your caster even, that is your pull.

I did adjust the caster offset as you requested and it still pulled right.  I haven't checked the rear angles yet but the leaf bushings are a must.  They are so dried and brittle they are flaking off to the touch.

What were all of your final settings?

[chargd72]

Left:  -1.1 camber       Right:    -1.1 camber
          5.1 caster                       5.5 caster
          .15 toe out                      .15 toe out

The car wandered just as bad with toe in as well.

Edited.thats alot of camber for a street car. -.5 is plenty for spirited driving. If you wish to keep that much camber, then i suggest also moving the left side .2 more positive then the right. On a rear wheel drive car i dont reccomend toe out but you have so much negative camber that you may be inducing your wander because of it. The toe out will help control the instability some, but i suggest less negative camber and toein
When you were aligning it, did you take note of the thrust angle?
