Exclamation Weak Power Steering Pump?

At idle, my truck has a hard time turning the 35" tires I have. Anything higher than idle, and she is good. Basically feels like I'm in manual mode.

Is this nature of the beast with a PSD over the axle and oversize tires? Or do I possibly have a problem. Last time I had a problem like this, it was because my Bronco had 283,000 miles. PS pump was a bit worn out on that rig.

Mine turns 33" tires with no problem. I don't think you should be having problems with 35" tires on a truck that has as few miles as yours.

I would try flushing the PS/PB system and filling with a good synthetic, like Mobil 1 A/T fluid. Then see what you've got.

I agree. Try flushing the PS fluid. I've heard this does wonders.
