1992 Mercury Marquis Repair Question
Mercury Marquis Steering Problem
Why do you not believe three different experts? Are you having to add power steering fluid? If not, it's not power steering fluid you're seeing.
If you can stick your finger through something, it was either built that way, as in a bracket or engine mount, or something is obviously broken.
I guess I need to back up. What do you mean by "gear box". To some people that means the transmission but you listed a steering problem. I show a normal steering gear box and a rack and pinion assembly available for your car. Which do you have? Neither one is filled with grease. Both are lubricated with the same pressurized power steering fluid that operates them. Rack and pinion assemblies commonly leak from one of the end seals. The fluid will go from one side to the other through the small air transfer tube and will leak from the accordion boots on either end. Fluid normally leaks from the pitman shaft seal at the bottom of older-style steering gear boxes. Those seals can be replaced but that usually doesn't address the cause of the leak. Have a helper turn the steering wheel back and forth from about the 11:00 o'clock to the 1:00 o'clock position with the engine running. If you only see fluid running out when it's being turned, you need more than a new seal. If you watch that shaft real closely in relation to the housing, you will see it move sideways first, bottom out, THEN start to turn. Because of a worn bushing, that shaft is able to move away from the seal and let fluid leak out.
