For a couple years setup needed 20 North steps, same with West and at 30 min. good tracking. Now needs 40+/- steps and poor star images?

So little to go on.
Mount ? OTA ? ST-4 or ASCOM guiding ? OAG or Guidescope ? Guidecam ?
What did you alter that changed the Cal ?
Post two PHD2 GuideLogs showing the difference.

And where in the sky are you calibrating? At high declinations, getting enough RA movement to calibrate requires some adjustments.

ieq45pro, st4 guiding,asi 120 camera about 30deg up horizon. Graph shows DEC going off guide course. Cleaned cable also tried another cable, no change. I fear my 4 year old mount is losing dec communication.

How many pixels? It's easy to configure PHD2 to cover the usual 25 pixels on a single step. PHD2 will complain, the calibration will be bad but it will try to guide.
Lately I set it up to cover only 20 pixels. Works the same as 25 for me. During tracking, rarely my guiding goes above 1 px.
