Hello, once again I need some help. My steering was really bad, I followed the manual and did step by step checks. King Pins good, drag link ok, need to replace tie rod ends (next project)and finally got to the steering box. I decided to flush the box and put in new oil (Napa 80-120)before setting the two adjustments. Made adjustments with wifes help. Really happy with results. Now the problem (s); I have small oil leak through the threads on thrust adjustment. I did not put any type of sealer on threads, what should I use? Next, oil seal on pitman shaft leaks really bad (started after adding new oil). Since I plan some day to install power steering I don't really want to pull the steer box right now. Can I put a different type of lube in to reduce the leakage? Once again, thanks for any idea's. Roy
