Thanks for the help!!!
It just so happened that in Borisov, everyone closes at 19.00. And if you need to fix the problem, wait until morning.
I arrived at the Tech at 19.10 with a rumble in the rear suspension.
Well done guys. We looked at everything we could, and found the reason. We helped to find and deliver the necessary spare part. And until everything was done, they did not let go, and the time was already 20.40. There are more of these guys. I don't know what the master's name was, but thanks to the dispatcher Dmitry separately.
