What make/model cor is it? The arrangement of the trill beam can differ from make and model (eg. S5 and XL cors have a different arrangement), but generally the C-D trill beam on the top joint is the longest one and the one most likely to bind up if the pillars move.
On pro level cors with a combined trill beam with both the LH trill touches mounted on the same pinned steel, the C-D trill is in three sections all pinned to the steel axle while the other trill touchpiece for LH3 (B/C-C#) is free to move independently.
The trill linkage is prone to being bent on oboes/cors if the top joint trill keys aren't held down or the RH C-D trill key is held down during assembly or if the RH C-D trill key spring has gone so it's free to flap about.
