Steering Stiffness in 96 XJ
I drive my 96 XJ occasionally and when I do it's typically on the highway for a few hours at a time. Over the past two months (September & October) I've noticed that it's taking more and more arm strength to turn the Jeep.
I know that power steering fluid becomes less viscous (and thus less efficient) in cold weather, but, the weather hasn't gotten that much colder yet and it does not improve after the engine and environs have gotten to running temperature.
The first thing to go on the XJ after I purchased it (used, 3-4 years ago) was the power steering pump. It just failed one day on the highway. Since the installation of that new / current pump (3 years ago) I've had no issues.
I've not yet done any work on the system. Tomorrow (by the time most of you read this) I will have (hopefully) flushed the system with new fluid. The current fill of fluid is neither black nor foamy and looks to be in good shape.
I'm fearing that there is an issue that's burning up the PS pump and hoping to hear from you what could be causing that and/or any other ideas or experiences you've had with similar situations.
