Another Gldiator build
- Thread starter R3
- Start date
Love to, but entire drivetrain is 100k mile warranty and don't want to mess with that. After 100k I'll look to delete, unless current admin decides that making the DEF is less beneficial than just letting the trucks go.
I'm not anti-environment at all, but I am anti-"don't let me drive home because DEF heater takes a dump". Which has happened once already. $3500 DEF tank replaced under warranty in December.

Next up on the list Is the steering system from PSC and ACCUAIR. looking to work these over a 4 day working weekend. Thur-Sun this way I think I can get all the simple stuff done in 4 8-10 hour days. I know @3VOLVE is interested in helping maybe room for one more. Might add the new semi float to the list of to-do's that weekend as well.
@3VOLVE you can have the springs after the air bags go in if you need them for the HI Velocity Yellow Machine.

I may be free depending on the weekend as well if you would like some additional assistance.
Wish I could be there. I will be out of town mid-May.
Added a little more storage for my tow strap and Bubba rope. Install was fairly easy but cutting the aluminum tailgate was a bit of a challenge. Soap helped a lot in keeping the cutting wheel clear.

Little update on the EoC delete and Optilube additive.
I opted for the resonator exhaust system downpipe back. Note, if you order this system it doesn't come with the tailpipe this is not very clear when you order. Lucky The previous owner had a 3inch CAT back system already installed. Starting the truck is noticeably louder but in a hotrod way. Nice growl. On road cruising it is a touch louder than stock but not enough to warrant turning the radio up. Step on the throttle to pass and the growl is noticeable ( sounds like a 60s Dino Ferrari at full song). Best part is the tune 30HP and 50 torques and no smoke!
Tune from EoC is a towing tune. I wanted a tune that cleaned up the emissions crap and improved efficiency/power just a bit. The thing with Diesels is power is dependent on how much fuel you can burn. This in a compression ignition motor produces heat and the more power you make the more heat needs to be handled. This is why the new pickup truck front ends look like semi trucks. The Gladiator has limited ability to cool the power plant. On the forums there are lots of threads on cooling the 3.0 Eco diesel.
So back to the tune. This turns off the EGR , DEF, SCR systems. The EGR solution is a simple block off plate for now. Will look at a complete removal in the future. The new Pipe gets rid of the rest. Driving I notice a much improved throttle response right off idle, almost a little touchy. I do not have the trans tune installed yet so this is based on OEM tuning. The truck runs just like factory with more torque and better fuel mileage. When I picked up this rig the winter fuel mileage was around 17-19MPG. Enter Opti Lube XPD fuel treatment. This alone raised fuel mileage to the 21-22MPG range. Now that the rig is tuned and deleted I am clocking 25-27MPG. The test track is a 124 mile round trip to DC from King George with a mix of stop and go, stupid traffic, and cruise on 301. My rig is running 4.10 gearing for now and 39 inch BFGs with flat front fenders and a 3.5 Clayton overland lift. I have been holding speed down to 60-65 mph on the open parts of the ride. I am seeing 400 miles of range on a regular basis but only if I take the time to fill the tank completely full. the extra 2-5 gallons makes a difference.
Overall I am very happy with the EoC system with the exception of the Catch Can mod. the tuning needs to accommodate this modification to keep the CEL off. Also since it is a CANBus system, the extension harness is a critical part of the system and if resistance is too high the whole system freaks out. For now I will leave the CC off.
For those with EcoDiesels, the fuel additive is a must to improve lubricity and reduce the potential of CP4 failure. The Deletes, will only serve to make you diesel live a long and happy life keeping the soot out of the combustion chambers. The EGR process is quite detrimental to the diesel engine.

Great write up and great info to have.
I am not a fan of OEM warrantees anymore, they cover enough but just enough. the rear axle shredding itself is due to a bad bearing design.... Had to replace and pay for it due to it having 4.10 gears......factory replaces the OEM parts and the design is still bad.
My history with Diesels, Detroit Diesel 12V92... semi pulling rig.... No emissions Ford 6.9IDI natural motor. Upgraded with a turbo and adjusted fueling. Ran 350,000 miles without a hiccup. 97 Power stroke 7.3 motor, some tuning ran 400,000 before selling. still running strong today. 2005 6.0 motor. Tuned and deleted with Head studs, still running strong after a turbo replacement at 225,000, 2008 F 450. full deletes, turbo upgrades, injector upgrade made 650HP and 1460 torques.... current owner is still working the truck as a Hotshot service approaching 500,000 miles and a second set of turbos.
I have friends that wait until the warrantee is up and end up trading their truck due to issues caused by emissions equipment or shortly after the delete kit installed due to build up of soot and damage caused by such. While there are some rigs that must have been built on a Friday and will have issues most will not ever need the factory warrantee to be exercised.

The evolution continues. Datin Fab rack installed last weekend over the Softopper canvas. Lots of parts and nuts and bolts galore. In the end a very solid rack. Installed the Overland systems 270 degree batwing. Now all that is left is all the rest. Will shoot a picture or two later this week.
Working on an enclosure for the aux power and second battery. Looks like all this will live behind the driver seat after removal of the 40 side of the rear seat. Still lots to do and time is running short.

Had a great weekend with @3VOLVE installing a complete PSC steering system in the Rattle Wagon. Despite the jeep Diesel being small... it still takes up a lot of room in the engine bay. Pulling inner fenders, boost tubes, air box and associated mounts makes this a 4 hr job with two competent set of hands turning wrenches.
Net result Steering feel is about the same but no more play. My rig had almost 3 inches of dead area in the box. New box is tight and responsive. I will have to learn how to drive all over again. Something of Note, we did not install the ram ( stock steering) so If anyone is in the market I have a complete ram assist for a stock JT/JL steering system. The aftermarket knuckles and steering gear installed requires a separate mount and a special cylinder. All to be ordered soon.
Next big rocks in this build:
Aux Power cubby in the coming weeks
Accuair suspension and rear axle install. Hopefully 2nd or 3rd week of May before it gets too hot.

I need to get a PSC setup done in the Gladiator before we head out west. But I think i am doing so other radical mods first. Rear seat delete, flatbed conversion, etc. When you are playing in the rock gardens ram assist is a must with 37" tires or bigger.
What I found with Ram assist has nothing to do with the size of tire. it has all to do with stress on the steering gear. The Red Jeep was no stranger to big rocks and had been on 37s since shortly after buying it. What I found is tie rods and Drag links take quite the pounding trying to battle big rocks and odd angles. This stress broke a Drag link end at the jam nut one time and broke the drag link itself another time. Sharing the steering load with a slave cylinder take a lot of stress of the single points of load for the drag link end and tie rod ends. Sharing that load across both allow the steering gear to live longer in tough challenges.
Physics plays a role too. if your wheel is jammed against 10 tons of bolder or a huge clay wall, no amount of force will turn the wheel as the rock or clay wall will always win. On the flip side if the wheel can steer the cylinder will make it easier.

Eh, my experience is a little different. While I agree with most of your points, without hydro assist, even on flat/level ground, if I have a 12.5" - 13.5" wide tire deflated to 7 or 8 PSI, I can't steer at all unless the vehicle is moving. I never have that issue with tires that are 11" wide or less. I never needed ram assist to deal with stalled steering with 35" or smaller tires.
