Power steering wanes at warm idle
1992 Laredo 4.0L
I start up my Jeep after sitting overnight and the power steering works fine. I can turn the wheels both directions with ease as the Jeep sits at idle.
After I start driving for a bit, and the engine gets warmed up, the power steering fails if I try to turn the wheels while stopped at idle.
If the Jeep is in motion, or if I raise the RPMs while sitting, the power steering works fine.
Hopefully, I'd like to diagnose this problem before I start throwing parts at it.
