I’m at 192,200 ready for the next oil change/tire rotation. Liberty is running very good. How many miles can the bottom end go? Hoping for 400,000.

I’m still using Mobil One 5w-40 as directed by the owners manual. While doing the oil change found the front driveshaft needing to be serviced along with the power steering pump. Ordered a rebuild kit for $88 plus tax for the driveshaft. Wondering if a reseal kit is available for the power steering pump. With summer not far away thinking the hood vents that WWDIESEL installed would be a good thing to do here in south Mississippi for the summer. Also been running 42 psi in the Uniroyal Laredo tires and will go with 38 psi since the steering is a little twitchy. Detroit TruTrack would help to keep the Liberty from changing direction when I get off the throttle I hope. Setup a tool trailer and now using the Liberty to tow to job sites. The rear airbags work well to level the rear. Weighed Liberty and trailer at local landfill. Liberty is 4500# with me by myself and with tool trailer is 8500#. Coolant gauge stays a tick below the halfway mark all the time.
