Hello!
In the warm season, there was not enough cooling for the power steering system. After active movement with intense steering, the steering wheel became very tight.
Maybe this was due to the width or size of the wheels.
And maybe the insufficient performance of the elements of the hydraulic booster system
Changed the pump to a model for a diesel base 2500 .....
I bought from America Remanufakturing AC Delco Professional steering gear .... for $ 500. By the way, disgusting quality and assembled from improper components. The shaft with the torsion bar was not from this model of the steering gear.
I am disappointed!
In total, $ 500 for the wind and the steering gear in the form of unnecessary parts and useless scrap.
The old steering gearbox has received full service with a complete repair kit of oil seals, bearings, rings and more ....
And implemented in its rightful place.
By the way, my friend and, in combination, an excellent auto mechanic, said that if the problem persists, he will install a steering rack from Toyota Sequoia in my Suburban.
But, with the capture of Toyota, we decided to wait).
And, here, Mopar is dearer to us in religion)
So...
Captured a radiator from Chrysler (from Grand Cherokee) .....)))
As an additional cooler, he introduced it into the power steering system.
Used Gudear hoses.
General understanding in the photo.
Now everything is fine and the steering wheel is light in all driving modes.
P.S. If the Google translator makes you laugh and mislead, then this is only his fault)))
