Six Packers,
Finally after repairing my frame and installing new bushes and up rated
springs from TRF, the frame is on all four wheels again, but that's where the
trouble begins. Note- trailing arm boxed sections, lower cruciform and other
pieces were replaced ( see web page if interested). I was very careful in
putting theses sections in and used a strong back to keep the frame from
flexing.
It's just a bare frame sans engine, trans, and body. Unloaded that is. When
I look at the rear wheels the lower edge (Toe In?) is in A LOT more than the
top of the tire. The leading edge of the tire is in a lot to compared to the
back of the tire. I know shims will cure some of this as will the weight of
the drive line and body, but things look way out of kilter. I messed with the
shims by removing all or adding up to five at each bracket to see the effects,
but the wheels didn't change that much.
I've put a straight edge across the forward end of the trailing arm boxes
perpendicular to the frame (perpendicular to the Datum line) and it looks
fine. No drooping of the frame out riggers. Then compared and measured the
left and right points of the frame where the bumper brackets would attach
(front and rear) and there was only 1/4" difference between the left and
right sides. I didn't compare the front to the rear, since the frame was made
with an upwards bend at the rear.
What is normal (?) for the rear of an unloaded frame? I'm sure things will
settle some, but how much is to be expected. Should I not even worry about it
till the frame is loaded up?
Oh, yeah, I've double checked the trailing arm brackets and I have one notch
ones to the inside with the notches up and two notched ones to the outside
notches also up. It is a '69 so the three notched ones aren't used.
