ATA and BTA casting numbers on diffs. I THINK it relates to the manner in
which the geary-bits are mounted together inside the case, ie the BTA
carrier is a more substantial casting. Am I thinking along the right lines?
Can a BTA carrier be used inside an ATA case? Can the crown & Pinion from
one model be used on another? Has anyone actually broken a diff internally.
If so, why and where did it fail. I'm interested in finding out where the
weakness lies.
On a related matter, am I right in assuming that a correctly assembled recon
diff should show signs of wear evenly either side of the middle of the teeth
on the crownwheel or should it be irrelevant where the teeth touch?
