Why would a Rack and Pinion on a 2002 Trailblazer leak?

A Rack and Pinion on a 2002 Trailblazer may leak due to worn seals or gaskets that have degraded over time, leading to hydraulic fluid escaping. Additionally, damage to the unit from impacts or corrosion can create leaks. Low fluid levels or old, contaminated fluid can also contribute to seal failure. Regular maintenance and inspection can help identify and prevent these issues.
