Hello,

I have a 99 4R that has stiff steering until warm or until I drive it and turn the wheel a few times.. It starts to happen when the temp is 50 degrees or colder.

I have replaced the steering rack and lines. Pump reservoir is clean as a whistle and has new o-ring, no leaks. All steering components are new and everything is oem. The stiff steering was prominent even with the old rack during fall/winter.

The fluid in pump reservoir is spinning/circulating slowly while engine is running, no bubbles. Im not sure how much it's supposed to spin. Any idea? Slow spin or hurricane?

New synth fluid, no squeals from belt. maybe a little at full lock once in a while.

Does anyone know what the problem is? Can it actually be the pump? The belt is working and fluid is circulating..

Any feedback is greatly appreciated.
Thank you
