Dragster Steering Box Maintenance /

I was running the dragster lately and found that the steering would lock right up in one direction but not the other. I’ll tell you that it was a bit scary… anyhow, I eliminated all moving parts of the steering system until I found the culprit to be the steering box. After pulling it apart and cleaning the old grease out, the actuation was automatically better. So I liberally applied new grease to the steering mechanics and it works flawlessly now.
I’m not sure how often that I should put new grease in there, but I’ll know right away what to do when the steering starts to get heavy.
For what it’s worth, this steering box has “P-S Mach. Prod. TAK” cast right into the aluminum.
Hopefully this helps someone else with the problem.
