Jeep 20,000 Mile Check/Inspection

The fist “major” inspection for the Jeep Wrangler JK/JKU is the 20,000 mile inspection.  I do routine maintenance at 5,000 tire miles for a 5-tire rotation, and I use the oil life “%” as the schedule to do oil changes.  

As you can see below what you need to inspect, I used this opportunity to also do a general look at all the major parts of the jeep wheel it was up on the lift.  Dee has always been a huge help when it comes to general and upgraded maintenance items with my jeep and all my family vehicles.  

After we got the tires off we were able to inspect the brakes.  The Jeep Wrangler JK/JKU is the only vehicle that I know of that the rear brakes wear faster than the fronts.  I think that is because the advanced roll stability system that the jeep uses and it “pulsates” the brakes when needed.  I think that the system uses the rear brakes at higher speeds and around corners.  So with just over 20,000 miles, I need to replace the brakes.  I do not know what Im going to do.  Do I upgrade to a big brake kit? Factory replacement? Upgraded factory replacement? I am not sure, but need to get this addressed in the next month or so.

Next we inspect the tie rod ends.  The Synergy tie rod ends are filled with grease, grease does seam out of the rubber boots and make a mess, so wit the tires off we can clean and inspect the boots.  All looks go, boots have a good seal, the retainer ring is seated properly and we top off the grease.

I recently changed my front and rear differential fluid so we don’t need to address that item on the list.

Going down the list, we inspect the CV/Universal joints, and all the suspension.

Adjusting the parking brake is not an easy task, you actually need to remove the brake caliper and rotor, so I will leave that until we replace the brakes soon.

Now with the 20,000 mile inspection complete now to a few other items to do while the Jeep is up on the lift.  I need to install my Rock Hard oil pan, and transmission skid plates and the AEV rear differential skid plate.  As I have said in the past I remove these three skid plates when I am not off roading or for the winter.  I reduce quite a bit of weight and it reduces the rust on these as the winter road salt is very abusive to metal here in Ohio.

With everything complete, now off for a few camping trips and start researching what brakes to buy.

As a Boy Scout Eagle Scout, camping, camp fires and maps have always been a passion. After getting my professional carrier established as a Boeing 737 Captain for a Major US Airline, I was able to get back to my routes of playing in the woods, mud and building things. I got my first Jeep in 2012. It was a 2002 Jeep Wrangler TJ, I did not modify it, and it had many mechanical problems, as I was a novice, and not mechanical, I sold it for a new 2013 Jeep Wrangler Sport Unlimited. In 2014 I installed an American Expedition Vehicles (AEV) 2.5" lift with Kelly Safari 35" tires. In 2015 I continued my build with AEV front and rear bumpers, snorkel, skid plates, and off road lights. Up until now, I did off-roading at the local Southington Off Road Park, Rausch Creek in Pennsylvania, and Badlands Park in Indiana. JKFreaks.com was an outstanding resource and I was able to make life-long friendship. In 2015 I did my first big trip with the jeep, first we stopped in Ouray, Colorado. We had two days of trails and did Imogene & Engineer Passes. I left part of myself in the San Juan Mountains and my want to return has been strong since. After Ouray, we went to Moab, Utah for Jeep Jamboree. Moab is "Jeepers Paradise". Endless miles of trails, from dirt roads to the most extreme, Moab offers endless possibilities for the Jeeper, hiker, mountain biker, everyone. Since 2015 I have returned to Moab in 2017 & 2019. In 2018, I traded in my 2013 JKU Sport for a 2018 JKU Rubicon Recon. I did this drastic move, because I was at the point in my build where I needed to upgrade my axels. I made the very difficult decision and striped as much as I could from my 2013 Jeep to move to the new jeep, as they were both the same style of jeeps; JKU's. I spent the spring and summer of 2018 to build my jeep. I once again installed an AEV 3.5" lift, 35" BFGoodrich KO2's and AEV front and rear bumpers. With this build I wanted to move from the "Rock Crawler" to an Overland build. I can still do all the difficult trail of Moab, Rubicon Trail, but also the fire roads and cover many miles full of camping and off road gear. With Overlanding in mind, I have build a cargo platform for my ARB 50q Fridge, and specific loading of the camping gear. Where is the Future? Buying an Earth Roamer and exploring as much of the country as possible? Thats a goal, but I hope in the coming years to get a roof rack, roof top tent, and then doing more Expeditions though Appalachian, Rocky Mountains, desert of New Mexico and Arizona, and the National Parks west of the Rocky Mountains.
