Offset T/A Rubbing - Can Someone Explain This?
My passenger side brand new offset trailing arm is rubbing the frame pocket on the inside of the passenger side. The car has never been wrecked and the old trailing arm never had a problem.
When I installed the offset arm and had the car aligned, they could not get the toe set - even after removing all of the shims on the inside. I called the T/A maker and they said they have been using the same jig for many years to make the arms and it could not be out of spec. They suggested I check the side yolk play. I do have some, but I guess I do not understand the geometry at work. I could see yoke play changing the alignment after it is set, but how could it force me to remove all of the shims on the inside of the arm to come close to zero toe just for an initial setting?
I am having the differential rebuilt in a few weeks and I am debating if I should remove that arm and have it checked.
Any thoughts on what this could be? Again, I had no issues with the stock arms.
Thanks!

Were you able to check the pocket before you put in the new TA's? I know some folks had problems when a previous owner had lost or removed some shims and just tightened down the bolt, crushing the pocket and making it 'wonkey'.
Were they able to get the toe set on the other side? Did it use excessive shims on one side? I'm just wondering if there was something with the geometry of the rest of the rear-end.
Lastly, are you using stock camber rods (with the cam bolts) or the upgraded 'turnbuckle' type rods?

Hmm, I would take it somewhere else to get the alignment checked out. The TA's should end up close (ish) to the center of the pocket or at least be about the same on both sides and the front and rear wheels should either be in the same plane or the difference should be the same on both sides. Your car may have been wrecked back in its checkered past. you can take a tape measure to it and see whats going on. Measure center to center front to back, side to side and corner to corner
