I have an older circa 1987 16 hp 6 speed 44" ride on mower. One of the tie rod ends keeps dropping down from the steering plate where the 2 tie rods are under the steering plate or bellcrank as the part is called in the parts manual. Not sure on the best remedy I was able to push it back in but it will not stay for long any suggestions will be appreciated. Can't locate a repair guide for this unit.
