Differential Fluid Change (JK/JKU)

Differential Fluid Change (JK/JKU)

This is a combo post with a little update on Dirty’s build and we made a maintenance “how-to” as part of the job. I’ll kick this off with the maintenance “How-to”. We strayed a bit from our typical write-up and opted for a video. It’s on changing differential fluid. While it’s geared largely toward JKs and the rear at that, much of the practices and certainly our opinions overlap many other makes and models of vehicles and axles.   As…

Klondike can now breathe a little easier

Klondike can now breathe a little easier

This is a little bit of old news to our Facebook and Instagram followers, but about a week go we installed an AFE Power cold air intake. Normally, we are not fans of CAIs, especially with the Pentastar engines. We know several people that have pretty severe oil consumption after running their JK/JKU (3.6L) in dusty environments. Sadly, many ultimately needed a new engine to resolve and the fault was put on the CAI they ran. Even the Mopar branded…

JK/JKU Parking Brake (E-Brake) Adjustment

JK/JKU Parking Brake (E-Brake) Adjustment

If you own a JK or JKU, and especially if it happens to be a manual transmission, you know how crappy the factory parking brake is. There are a few factors to this. For one, it seems the lever and activation mechanism is prone to breaking and, even when it is working “correctly”, seems to not reset well. The other major factor is in the drum itself. While it is supposed to auto adjust (we don’t see how), we have…

Getting Dirty ready for Spring!

Getting Dirty ready for Spring!

It’s been since mid November that we last made an update on Dirty. This is partly because we are nearing the end of her build (for now) but largely due to the fact we just don’t do much with her over the winter. Ohio roads normally see lots of salt and we just prefer to leave her inside when there isn’t a good reason to have her out. While we went into winter with some thoughts of doing some snow…

KL Cherokee 3.2L Pentastar Engine Oil Change

KL Cherokee 3.2L Pentastar Engine Oil Change

No matter how you use your vehicle, routine maintenance is a necessity. Changing the engine oil is one of the higher frequency ones. Sure, you could visit the local quick change place and have them do it for you, but really, it’s a pretty easy job that can be done with a few simple hand tools and time. Hopefully this “How-to” write-up will inspire you to give it a go.   Before you begin: As I mentioned you will need…

PUG Update (Engine not the Dog …or is it?)

PUG Update (Engine not the Dog …or is it?)

David Zats with Allpar released an “update” (if you want to call it that) on the almost forgotten upgraded Pentastar V6s. If you read that sarcastically, that is good because the update is that there isn’t one beyond “it’s still coming”. That’s right… no dates, no information on what vehicle will get it, nada! There is some chatter about competing with other V6s backed by multi-speed transmissions. To this I would say, work on housekeeping of what you have before…

JCR Offroad JK Inner Knuckle (“C”) Gusset Review

JCR Offroad JK Inner Knuckle (“C”) Gusset Review

With every Jeep generation release there has been improvements when compared to it’s predecessor. Unfortunately, sometimes these improvements create weaknesses in other areas. This is exactly the case with the JK’s inner knuckle or “C”. The JK Inner knuckle is larger than previous Wrangler generations which allows for larger u-joints. The larger u-joints are great, but it seems opening this knuckle up to make room for them increased the leverage just enough that the “Cs” themself are now a weakness and are…

Looking for more power? 345 & 392 Hemi Crate Engines are available from Mopar!

Looking for more power? 345 & 392 Hemi Crate Engines are available from Mopar!

Let’s face it… most, while we love our Jeeps, it sure isn’t because of what’s under the hood… Unless of course you have already swapped out the engine 😛 Luckily for all of us still singing the high RPM song on hills have some off the shelf options from Mopar. Just in time for SEMA and showcased in an awesome concept, Mopar released several crate engines..   Mopar launched several create Hemi engines on November 1, 2016, to make it…

ARB failure testing

ARB failure testing

I thought this was a cool video to share. We run an ARB along with 35 spline axle shafts in the rear of Dirty. We made this change when we needed to replace the factory locker and have been very happy with the upgrade. Yukon now has a line of air lockers that I believe are essentially the old ARB design. After watching this video you might get an indication of why they should not be compared. ARB continues to…

2007-2011 (3.8L) JK/JKU Oil Consumption FIX!

2007-2011 (3.8L) JK/JKU Oil Consumption FIX!

There is no doubt that the 3.8L V6 engine that is found in early JKs and JKUs provided barely sufficient power for the minivans it was originally intended for. Still, when you think about all the Jeeps that are ragged on pretty hard and revved to the limiter on the trail, the little engines do seem to be holding up fairly well. Don’t get me wrong, I’m not a total fan of the engine. In fact, I find it down…
