Manual Steering

[DVT873]

Probably RH Sheppard gears. The phone help used to be tretty good. Have not had to call them for a few years. Good info on their website https://www.rhsheppard.com/customer-serv...bulletins/ If the bot takes down the link google RHsheppard power steering. Should come right up. Had a truck long time ago that one of the gear gear hoses had gotten hit and was restricting flow. In a few cases the truck builder doesn't put a big enough pump on.

Bought one of their flow and pressure test units decades ago. Pricey. http://www.rhsheppard.com/wp-content/upl...2-2019.pdf Rarely ever need it but sometimes it is the only way to find out what is going on. Hopefully you won't need to go that far. Good luck.

If it isn't Sheppard look up TRWRoss. They did not do much with dual gears.
