Repair tips?

Hello, my friend ordered the following for my S60 T5: 2x crossbars 2x trackbars 1x upper motor bearing makes approx. 550 € *sigh* The upper motor bearing is not a problem according to VolvoProfi… Has anyone ever changed the crossbars? Do I have to hold the spring with spring tensioners in check, or how? I ask all these questions now without having seen in the service manual. the trackbars should not be the topic! Are 106€ measured for the track in order? I am happy about tips!!! I’m going to do the oil change. I had a Motul oil, I believe 0 or 5 W 40. Can this be? But has not been one of the Volvo recommended ones… What do you mean? Greeting, Tom – the next weekend dances under the elk 😀 … and is looking forward to it already. Finally push the keyboard aside and take the screw key in the hand.
