The JKU storage is about 100mm in length and width shy of being convenient for storage. You can make the most of what you get to make it work but it's certainly not as easy as the options available for larger wagons.

If your coming from a diesel Patrol to a petrol Jeep and even the torqy little pentastar you are going to have to change the way you drive. IMO these petrols need to be run between 2400 and 4200 RPM and to be geared low to accomidate the higher rpm and then they plenty capable. So many of my mates can't and don't like to drive my Wrangler because they are just diesel lazy, and can't change their style.

Not all Wranglers are created equal, if you can I'd get a rubicon, if not I think you will want to re gear to at least 4.1 but might as well go to 4.56 if your doing it for off road use

Stock axles are good for about a 33" tyre and will need replacing if you want to go bigger offroad imo. The rubis maybe good for 34 or even 35.

Balls, unis and bearings are fairly frequent maintenance item I don't know how much this varies from the patrol I would think slightly more frequently due to the heavy duty build of the patrol but not too sure. I'd say their an 80 to 100,000km schedule item.

The unsealed electric thermofan in the 3.8 can be a cause of distress for water crossings and deep mud. But can be replaced with a sealed unit or you can let your car cool fully before crossing and drain/clean the mud after crossing. Not sure if they fixed this on the 3.6.

The Engine Coolant Temp sensor in the 3.8 is a cheap item that can cause headaches as well, pretty sure they can be bypassed with a switch to manually control the fan not sure on the he 3.6. Replace them every 2 to 3 years and you shouldnt have a drama. Carry a spare if you see the needle get to half way and the fan isn't cycling odds on you need to replace the ECT sensor.

The catalytic converters in older vehicles can start to cause people grief particularly the oil eating 3.8 for short transit drivers. These and DPF's are going to be the bain of all modern engine owners existence. Look for a car that gets driven moderate to long distances regularly, the cats will likely be in a lot better condition than an around towner.

The 3.6 is definitely a bit of a different engine. The 2016 and later versions had a host of upgrades including liquid cooled Exhaust Gas Recirculation. Not that i've heard of many issues with them but for me it's too early to be reliable so I'dd be looking for a 2013 to 2015 model. Probably not too many hassles servicing them but I wouldn't think it's going to be an easy engine to backyard rebuild. Not many of the modern engines will.

@OzRick25, great info, thanks. More things to keep in mind.

Yes diesel can make you lazy, you get to enjoy that low-RPM torque, can make life a bit easier. I drove a JKU and it took a bit to adjust to the petrol engine and its characteristics. Wasn't a bad experience at all, was a fun drive.

I'd like a Rubicon but there's no 4 doors for sale at the moment. I suspect they'd be more $$ than I'm willing to pay, too. Do you rate the regearing in the top five mods to do? Usually I'd attend to bar work, lift, tyres, storage, and then lighting.

That all depends on how often and how seriously offroad you get. Most offroad I do is Vic high country. My priority would be the tyre I need to get me where I need for me that's only a 33, then the gears that will run that tyre comfortably, and the minimum lift to clear them. Depending on what diff ratios you end up with and tyre size you feel you need you may find your ok without a regear. If you end up with with 3.73 in an auto you may find your happy enough turning a 32 or 33. Obviously if you need 35 or bigger a lot of that stuff is going to have to need to happen pretty close together. And before you go messing with lifts it's best to know how much weight you'll be carrying and where that will be to match your shocks and springs correctly so bar would be ahead of at the same time as a lift. gets expensive quickly sometimes...

I wouldn't do much permanent stuff in the storage department until you have lived with the vehicle a while as you are going to want to work out how to maximise every available space, there are a lot of different things people have done on here and in the US so you should be able to get a few ideas. I'm not sure how long the waco 40 is but the rear storage area only gives you about 750mm length between uprights (my 38l Engel eclipse just fits with one handle removed). Saw wise I have been chucking the 038 in the rear passenger footwell but have just got a smaller ms250 I'm hoping will fit in the rear. I have a king swag that goes on the rear seat or up on the roof rack if I get desperate.

Which Wrangler do you have, and which engine?
I've always liked the look of the Jeep going right back to the CJ but never considered buying one.

One day I decided to buy a cheap small 4wd as a second car, something to bash around and not care about. I bought a TJ Wrangler and fell in love with it immediately, as soon as you drive one with the top down on the beach, they are completely different to anything else out there.

I bought the JK (2011, 3.8L) and have spent a lot of money getting it to how I wanted it to look and don't think I'd ever go back to any other 4wd brand.

I wasn't sure at first but I was sold after driving a JK and having the opportunity to take it offroad. It's not for everyone, which is why I suggest test driving a few, but it has a unique character and feel. The solid axle on-road handling (or lack thereof) probably won't come as much of a surprise to you but it definitely feels different to the Patrol.

While the smaller interior is something to consider, it's more modern than a Patrol and just as comfortable in my opinion. I have packed two double swags, a 50L Waeco CFX, a 60L plastic eski, two bags of wood, gazebo, folding table, gas stove, a container with misc goods, chairs, bags, sleeping bags and pillows and managed to fit it all inside with my amazing Tetris skills but that was with both sections of the rear seats folded flat.

I have gotten smarter since then, with a DIY roof platform for bulky things like swags and camping gear that packs up small enough to fit inside, like the gazebo that I can fit in width-ways to sit on top of the fridge behind the rear seats.

The two best things about my Jeep is that it has allowed me to DIY just about every mod you can think of and also the Jeep community - there are heaps of clubs with organised activities and heaps of camping opportunities.

Well, actually there are 3 things if you count my current JKU's 3.6 compared to the JK's 3.8, which sounded nice but was very thirsty and lazy as all hell to boot.

"13 model, but I'm really looking at any manual 3.6L, 100,000km or so, and less than $30,000."

Mate, I just got a JKU 2013, Manual, 35,000kms for $26,000. You'll have no trouble finding one for under $30,000 if you're happy with 100,000kms

Plenty of really good info in this thread so far.

Just to throw my 2c in.

Storage has already been covered. The JKU is on the small side, but I personally have found the space more usable than a typical big open cargo space in a wagon. I manage to stuff a bunch of stuff up around the roll cage, and there are aftermarket bins that you can get that sit in the dead spots over the rear wheel arches, I have my 2nd batt on one side and compressor on the other. Whereas in previous vehicles all this stuff was just flying around the cargo area. When we go away I put my 40L Waeco on the back left seat and strap it down there, as we don't need to fit 3 passengers on the back seat losing one to the fridge is no big deal.

Roof racks will generally cost you more than an equivalent size rack on a wagon. This is becuse the JK needs the rack to transfer the weight down to the chassis/tub/rear bumper/a-pillars depending on which type you get. Most of the decent full length roof racks will have a exo-cage style mounting system onto the a-pillars and rear bumper/chassis. I have a RhinoRack 3/4 length roof rack with their backbone system made specifically for the JK that has an internal structure inside the hardtop that transfers the weight done to the tub, is rated to carry 120kg dynamic weight, I am not sure what the other full length racks a rated to carry.

Other's have touched on the massive aftermarket support. But also when it comes to servicing, there are so many passionate Jeepers out there that there is always someone else who has been there done that, so it's very easy to diagnose and fix anything that might break or have funny symptoms.

What lift and tyre setup does your Patrol currently have? Has your Patrol ever struggled on a track offroad due to needing more lift or bigger tyre? Has your Patrol ever struggled onroad to drive it's tyres and weight say uphills or reaching your fuel economy target?

Do you expect that the JKU will perform better in any/all of those situations? Or are you happy to just update your vehicle and take it from there? I am not sure what your expectations are, but if you watch Ronny Dahl's vids on youtube, his dad's 2007 JKU on 33" tyres and stock driveline (i.e. open diffs + traction control, standard gearing, standard front D30 diff and housing), auto, front swaybar still connected (usually the first mod for most Jeep owners is to fit disconnects)) goes everywhere with little to no fuss that Ronny and co's 79 series Cruiser's with 35" tyres twin locked etc goes, and carries all the camping gear that he and his passenger/s need.

I have a 2009 JKU CRD. Like you my last 4wd had done 316,000kms when I sold it and I did all the work on it myself. Serviced every 5,000km as well. I knew it very intimately. I also loved it to pieces, what started out as just a bunky 'cheap' 4wd to get me to my fav camp spots while I didn't have a job, ended up being the longest I've ever owned a vehicle and the most reliable, it had got me all over WA without any probs. But so far with the new (to me) JK so good. I love it heaps. I have done all the work on it myself as well apart from things that I can't such as dyno tune and ECU remap etc. I find that it is a simple vehicle, very easy to work on (the CRD's engine bay is more cluttered than the petrol), simple susp, simple steering, simple driveline, I also service it every 5,000kms and its very easy. JK's are built like lego, everything simply bolts on and off, no weird hiding places for bolts that you can't get to like every 2nd bolt on any Toyota vehicle. My only purpose for owning a 4wd is to get away and explore, and ideally to remote places, not so much hardcore social wheeling (which is what most people all over the world seem to use Wrangler's for and less so for touring/overlanding). My longest trip so far is 12,000km Perth to SA to NT and back again with many kms spent on dirt outback roads where we could, it takes time to build the confidence up in your vehicle after the last one has done so well but for me I'm almost there again with this one, as no issues at all and it just handles everything so well.

That's an unreal purchase. What state are you in? I find in NSW there's heaps of JKs but not so many JKUs in 3.6L.

My Patrol has a 2" lift with 33" tyres. Offroad, it's a good combo and I've never turned back on a track - just pick a suitable line and go at it in the right gear. On-road, though, there was a noticeable change in performance after adding the lift and tyres, and it was expected. The 2.8L engine can struggle on hills, in a 110 km/h zone uphill I might do 90 kmph. This also means it runs at 17L/100km when loaded with camping gear.

From what I've read on the forums, 14L/100km in a JKU 3.6L is normal?

Actually the first thing I did was search Ronny's channel to see if he'd done a modified episode His dad's Wrangler has a good setup, it's a good reference for my own needs if I was going to build a Wrangler for touring/camping.

Your entire last paragraph is exactly where I'm at right now. Know the Patrol so well, hard to part for something unknown.

Interesting that you have the CRD. It's a 2.8L right? Do you find it lacking for power at all?


Wranglers get a lot of grief online and it's hard to discern what's just hating and what's legit issues. It seems that a large portion of the hate is based on issues with previous models, but it still gives me second thoughts.

How reliable will the 3.6L engine be after 200,000kms? 300,000kms? Will it last another 5 or 10 years? My Patrol is 18 years old with 306,000kms, could I expect the JKU to be around in 15 years with that many kms?
