Ah ha! I have been waiting for your answer. When I dropped the drag link it took about 100lbs to turn Dr. side wheel. To grease the king pin it would blow the top seal. I heated housing trying to get the pin to accept grease and reseated end caps. It took some grease but blew seal again.
The coach has been sitting for years and grease has turned to wax. Shop did not know king pin was stuck. I called him and he said steering should overcome stiff king pin. I kinda wondered on that statement.
I have thought all along that this is my problem. The wheel after grease is about 25% better but still stiff. I haven't driven it since greasing the pin.
Should I have them hone and re-grease?
This coach sat for years in the AZ heat. I do plan on changing the ATF in the steering system and filter. I heard the engine radiator fan make a sound like cavitation when I first left but it went away right away and didn't make any more sounds in 3K miles.
This coach is really low miles but sitting is its own worst enemy. Thanks for the reply's and any more input would help. It has been sitting for a year now since last trip so I too am to blame..Best, Don
