mackey58 Posted October 25, 2023 Share Posted October 25, 2023 Is there a way to adjust a steering gear box on a 90 RD.our mechanic thought there was to take out excessive play Quote Link to comment https://www.bigmacktrucks.com/topic/73461-1990rd-steering-box/ Share on other sites More sharing options...
mechohaulic Posted October 26, 2023 Share Posted October 26, 2023 possible to find out model of box ? sheppard/ ross ? '90 too new for me to correctly answer. in the day the boxes had a 3/4? lock nut on side adjuster had screw driver slot . big sheppard boxes had adjusters top and bottom but they were for pressure relief settings.non-adjusting power steering boxes ON occasion would improve with changing filter and fluid. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73461-1990rd-steering-box/#findComment-540994 Share on other sites More sharing options...
mowerman Posted October 28, 2023 Share Posted October 28, 2023 I know my shepherd does not have one, but all my players in the sector,shaft bushing but I’m sure he would’ve noticed that it’s very common for the gears to wear out after a long. Period good luck. Bob Quote Link to comment https://www.bigmacktrucks.com/topic/73461-1990rd-steering-box/#findComment-541105 Share on other sites More sharing options...

Joey Mack Posted October 29, 2023 Share Posted October 29, 2023 I assume you are checking for backlash in the box, at the steering box and not at the steering wheel? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73461-1990rd-steering-box/#findComment-541145 Share on other sites More sharing options...

Yea it needs a new box in my opinion, 466k ,for miles .now try to find one lol don't know if I would consider 466k miles totally relative to the steering box wear . could do a million mile cross country in a straight line very little turning at same time a unit running local or quarry type work steers more. if all checks ok from steering wheel to box ; wear defiantly in box ; I would attempt fluid change - whether new fluid of same viscosity or up the fluid to different type. auto transmission fluid to hyd or vise versa.
