Fwiw
93 250 with sub 50k miles.
I fought with this, did the springs to ZERO benefit , had it aligned zero benefit.
The kicker was/is....
I went it to the old family shop and explained my issues, please look at the pivot bushes and whatever you need to do to fix negative camber issue, and report the details.
I want the camber fixed.
Owners were on it.
You don't need piviot bushes these are good.
You just need adj. Camber Bushes ...
Employees set rig on machine and did an alignment....
Don't know how much they cared but "it's in spec"

aint the answer...
I asked boss ***?
He apologized and said
Yes it needs adjustable camber bushes, No my guys failed to do them.
Let me have it another day and I will fix it at my cost,( a $250 to me savings).
Looks good after they were installed.
