Does this mean I will need to replace the rack (~$1.2k with aftermarket parts)? How long can I go w/o replacing it?
Power steering fluid level in the reservoir is between min and max. I don’t recall topping it up in last 12-18 months or finding a leak underneath the minivan. I did not feel any perceivable deterioration in steering. I don’t drive it much but plan to keep the van for ~5 yrs.
