When the truck is not moving and idling power steering is intermittent. For example when you are parallel parking and trying to crank the wheels around you might get halfway and then all boost is gone. If you take your foot off the brake and let the truck coast a few inches the boost returns. The pump is quiet but I'm assuming that it is bad.
I'm figuring that I'm not the first one to see this and would like to know what you found wrong.
you are not supposed to turn the wheels under powersteering, while you are not moving in any vehicle... let alone the heaviest truck on the road...... my tires are oversized and do the same thing, i cannot remember how well it did with stock tires, but regardless your supposed to be rolling to have the pump turn the tires or it will cause pre-mature failure, it is not meant to handle that abuse... just keep it at a slow crawl while you crank the wheel.
Power brake boost is provided by the power steering pump, apparently not enough pressure to go arround.
