I just found that the seal for the output shaft (pitman shaft?) on the steering box of my truck is leaking pretty badly. Can someone tell me how hard a job it is to replace the seal? I have a factory service manual and it doesn't give any instructions for replacing the seal. And because of the power steering I know that there's some high pressure involved. I can pick up a rebuilt unit from NAPA for a bit over $200, I don't mind trying to replace the seal if I've got a good probability of success, and I don't mind replacing the whole box if that's the wiser choice; I only want to do the job once (it's darned cold outside - Northern New York).
Opinions?
Thanks,
Dave Young
