I have a 1990 ls400 and the tilt control makes a noise but hasent worked since I bought it and I have seen multiple videos on people fixing the power tilt by placing a washer behind the gear insdie the motor but I cant seem to figure out how to take apart the plastic around the collum it self and am scared of breaking it. Just curious if somebody else has done this or if the ucf10 is just entirly diffrent Please let me know. 🙂
