HA (above) crossbar

Hello.

says times it is possible to change the rubber bearings on the S4 V8 at the lateral handlebars on the HA (top) individually???

Audi meant the crossbars are only available for 115 EUR!?
But I really only need to change the two rubber bearings on the right and left side of the crossbar (top)!
Is that possible??
Has anyone done this on the part yet???

This is the part with the Audi-NR: 443 505 352 P
and 443 505 351 P

Thanks for the help

Greetings Thomas
