Tail vib diagnosis

[Mostly]

I have a lot of lateral vibration on my tail.
Up to around 10 ish
I would expect it to be up/down and front/ back
Does someone know what this means?

Merci

A. You could be loosing a tail hub bearing
B. The tail shaft has too much side to side play or the tail gear is loose on the shaft
C. Your tail grip angles are not equal. Tail grip slop! When the grips relax to the far grip slop angles the angles aren't equal. This can also be caused by other mechanical issues allowing the grips to angle differently. Such as linkage or even the slider control Y arm.
D. Slider chatter due to a slider bearing going out.

Hi
Thanks for the info.
I changed the tail slider bush/bearing assembly
Got the vibs down with main blades to under 3, so hopefully will be OK/

Thanks for the help
