I'm doing a major rebuild of the front suspension.  Before disassembly of
the right side, I noticed that the A-arm would twist with the trunnion
changing angle as I moved the stub axle back and forth.  Strange, I thought
until I found that the lower A-arm had separated at the weld points under
the trunnion.  No problem, ordered a used lower A-arm.  Yesterday, I started
putting the left suspension back together with new bushings, newly painted
arms and a new trunnion.  To my dismay, I noticed the same twisting action
on the lower A-arm as I moved the stub axle back and forth!  What's going
on?  Is this normal?  If so, the separation of the weld points under the
trunnion must be a common trait.  Is it??  Or are both of my vertical links
somehow bent out of line??
 
Thanks for any and all comments.
