Good morning brothers,

I have a 3-stop Tac-32 that was recently re-packed and new check valves. About a week after the repair crew changed everything I get a call and they tell me the elevator is making a loud noise when it gets to the 3rd floor. I get there, I ride it up and about the last 2, or 3 inches of leveling into the floor there is a hard vibration. Sounds a feels very rough. It’s just on the 3rd landing in that spot.

A place the car on inspection and ride it down, feels fine. Then I ride up and the car starts bouncing like CRAZY. Bump, bump, bump.

I’m unclear as to this being a valve issue or something wrong with the new packings. I pulled the up leveling screen out and cleaned it and also added a gallon of MaxGlide oil additive but no change in the condition.

Any thoughts on this?
