MN Model D90 Rock Crawler Steering Replacement

This is a replacement for the factory steering rod of the D90 Rock Crawler from MN Models.

The original steering has a lot of play and bump steering, meaning, the models either goes up or down at the front whenever you steer left and right. This is much less with this drop-in replacement (not completely gone at maximum angles).

The parts are mounted with some leftover screws of the D90 model. There are 2 ball joints which are snap-fit and work so far flawlessly for me. The servo part has to be printed with support under the ball. In my case, this surface was a little rough and I had to file it smooth. The 2 small walls on the lower ball are just for easier mounting and it does not matter if these fall of.

You can mount the servo part in 2 positions on the servo-horn. I have chosen the position closer to the servo.

I recommend to also adapt the original wheel knuckles and file them a little to increase the maximum steering angle.
