Can't keep my deck level

[BlazNT]

The parts all function as designed.....rotating the adjuster does move the left side up or down, it just won't stay where I put it..........

That is exactly why I asked if yours looked the same. If they are warn it could allow movement. Lock washers do not always work either. If everything looks as it should replace the lock washer with a new one.

The lock washer is there.
Guess I'll replace it and see what happens.............

Thanks!
