Set steering game!

Hello together, I’ve had a little bit of fun with my BMW E28 524d, a steering game, because of which you didn’t get a TÜF anymore. Since the TÜF, I’ve changed the middle track bar + all the other joints. I’ve set the track by hand a little straight, so after eye measure^^ because during the first test drive, the fall fit at all and the tires from 50 kmh, nice to start squeaking (starter error *gg*) According to the “So is made E28” I may have a steering game of 25mm maximum. According to my feeling, it has become a little better by changing the joints and the middle track bar, but I still find myself between 20mm and 25mm. But I would have liked, ideally, no steering game -.- I have already taken the cover under the steering wheel down and looked at whether with the steering stick, which goes to the steering gear, but there does not happen to be a game above. I have made the joints pretty hard too, so that there is not really a thing to be fixed there?
