try loosning the allen bolts on the bottom of the chassie get a thin piece of paper put between the spur gear and clutch bell slide the motor to the clutch bell tighten the bolts. try taking the servo horn off and the steering trim to zero on the controller point the wheels straight slide the horn back on fine tune with controler. check to make sure your battery is charged in your reciver pack when mine gets low my steering gets weak. check to see if your servo saver has enough tension on it. if it bottoms out while braking you might have to adj your brake bias less front brake more rear brake good luck.
