Type 85 Alignment - Caster Error Cause

[Evan Parker]

Bent struts are one of the spices of life :)  at least you don't have to
replace any of the subframe if it happened.  Go check the parts of the
knuckle and see if it's all gripped around the strut the right way.
Even if it's shifted, a tiny little bit it'll set  stuff off to go
wrong.  I bet $5.00 this would be what the issue is.

Bent strut.  Had that happen.  Only a frame alignment rack can check
these things as it locates the bottom and top of the strut and all
points of the frame and subframe.  Took out the dampener and heated the
strut cherry red and used a frame puller to bend it back the 1/4 inch.
Ah yes, we kissed a curb only a little bit.

That would be the only thing that could affect caster, yes (besides an
accident bending something).  Caster is not technically adjustable on
the type 81/85 or 89 cars, but there is some small range of placement
choice with the subframe mounting (slightly movable captive nuts in the
frame).

Can't figure that one out... once everything is bolted in place, there
should be no place that has play (I presume you mean "in and out" by
axial).

So it might be a good idea to pull the under-covers and take a look at
where things are moving.  Perhaps the bolt locking the shaft to the rack
input is loose, or the "breakaway" linkage thing could have some play?
