Not sure what you mean in end points???
Just reset the servo with the top bracket off and with the wheels straight and trim in the middle and dir set in the middle I put it back together,
I've done this a few times now and still get that noise but if I wiggle the steering left and right a tad it stops???
Also standing behind the car the car steers more left than right on full lock???is there an easy solution to sort that out???
Not even run the thing yet so just hope there's no problems :-(
