Problems with the print at a special hight; UM2

[Prinstonson 0]

At a special hight my Ultimaker 2 makes a weird displacement in y-direction.

what i have already done to fix it:

-cleaned and oiled the axles

-lowered the printspeed to 80 %, the heat is about 220 ° C

-the heatplate is tuned

if somebody could help me or give me some tipps i would be appreciated.

i add photos for a better recognition of the problem.
