Hey guys, been chasing a steering issue on my 40 and could use some help. This is a full Saginaw (3.5 turn) setup with @orangefj45 kit and the “ham” can/Volvo pulley. It started loosing assist when wheeling in 4WD, basically feels chunky with bursts of assist and non-assist when turning. I get some whine when it’s doing it. I’ve tried tightening and have replaced the belt, PS fluid level fine. It’s gotten progressively worse, where it now does it in 2WD in parking situations. I should note the 40 is locked (ARB) on 35s. What should I try next? Replace pump? Rebuild box?

thx!

Any possibility you don't have enough belt wrap around the P.S. pump pulley, should wrap 50% of the pulley, not just barely kiss it. Belt should only go from crank to P.S. pulley, then directly back to crank, that's how you get a 50% wrap.

If you hear a whine (as opposed to a belt screeching), that describes a pump problem. Pumps whine when they are low on fluid. Is it possible you ran it low on fluid and you now have air in the box and system? Good luck.

I suspect the pump, the belt has good wrap and temp doesn’t seem to make a difference. Suppose it could be air, but haven’t opened the system or let it run low.

Traveling and didn’t get to replace yet, confirmed good belt contact with pulley. Will report back after I replace pump and bleed system.
