How to attach high torque with moving wheel suspension?

Moin, as part of a track bar change on my car, I’m a bit desperate how I can/should apply the required torque of 165Nm of the track bar head to the axle/wheel suspension. The biggest problem was that the suspension turned at some point – for example, I pull the torque wrench on the right side to me (direction rear), which turns the suspension like in right-hand steering. To a certain extent, it can be resisted, but it’s not possible. At the end of the day, even a second man couldn’t do it anymore. I could have had the suspension turned on at most (and probably with force), but somehow that seemed wrong and I had some doubts about damaging something. Most videos just banged the head with the impact screwdriver, but I’m more of a fan of the right torque. Do you understand what I’m talking about? What possibilities are there? How do other screwdrivers solve the problem? I will have some time, if/if I have to change struts and crossbars – with the QL 165Nm are demanded again.. Thank you!
