    Yes they are E Rated. So are mine.

    Tire Pressure Calculation

    What these guys are saying^. Chalk test can help you dial it in but yeah go ahead and drop them to 36 if you'd like. You may notice more sidewall deflection when rolling over a curb or something like that, but the tires should hold up just fine even as low as 32 for normal driving. If you were...

    Tire Pressure Calculation

    What does your door jamb sticker say? I would run them at that pressure and see how happy you are. If your tires are E Rated they will never be as soft as the factory ride, but they shouldn't ride like they are made of limestone either. For the record I run my tires at 34 psi cold, the sticker...

    New Wix ED oil filter

    Haven't tried it yet, I have been using Doc's Diesel filters for my truck for the last year or so. However I use Wix filters for all my equipment at work and haven't had any issues with them in the last 5 years. I'd trust their filter on my own vehicle.

    Just bit on an ecodiesel

    Ditto to what UglyMonk3y said, I just roll my front wheels up on a set of 6 inch Rhino Ramps to get a little extra clearance. It's not entirely necessary but it makes it a little easier to do.

    An Engineer's Ultimate Guide To 3.21 VS 3.92 Axle Ratio

    Me and my 3.92's would love to help pull this thread to 3,000 posts! For the record, my previous truck was a 4th gen Big Horn 5.7 w/ 3.21's. it was a great truck too. But I love my 3.92 EcoD. When I ordered my current truck the E-Locker was unavailable on the 3.21 and 3.55 so it HAD to be a...

    TPMS range

    I believe from the factory the TPMS light will trip for a low pressure warning at 28-29 psi. I don't think there is an over inflated warning.

    Are there any high mileage Gen3 Eco's with stock tune on here?

    I'm in the same boat as tom318. 63k miles so not too high by any standard but more than the average lease term in 2.5 years of ownership. No tune here but I would consider one after factory warranty is up. Only ever had one clogged injector hiccup that was fixed by a long drive at higher rpm and...

    Question regarding weight in Truck bed:

    I think you're correct, In my experience my truck does seem to hold the road a little better when hauling something light back there. Had a few hundred pounds of tractor tires in the bed and she felt very planted.

    Tried using a zf 8hp transmission pan...oops

    I don't tow that often but I wound up doing mine at 60k and was kinda shocked at how dirty the fluid was. I assume a lot of what I saw was just break in material though. I'm not a transmission expert so take that with a grain of salt. My dealer wanted 900 if memory serves me correct. Doing it...

    No start, hard start

    Sounds exactly like a dead/dying battery. I would get the battery tested and replaced. An old battery can cause your starter or alternator/generator to fail early.

    6.7 fuel filters

    My truck runs the same primary filter. I'd recommend Doc'sDiesel filters.

    Fuel injector cleaning service star case - tied to fuel pump recall?

    Not certain as to what the Star case is tied to, but I will say my dealer tried to charge me 700 dollars for a similar injector cleaning service when my truck produced a CEL noting "fuel injection quantity lower than expected P026C." Read as, a partially clogged injector. Even with truck under...

    *Ecodiesel Owners

    Mine also indicates 19-21 PSI when warm and idling in gear. I'd definitely be heading to the dealer if you're smelling burning oil, could just be a little residue burning off, or it could be a serious issue. Fingers crossed for you.

    Slumping fuel economy

    Alignment, tire pressure, brakes dragging, wheel bearing failing, differential oil breaking down, dirty air filter, dirty fuel injectors, blocked fuel filter. A whole lot of things could be causing it, and I don't want to insult anyone's intelligence. But, maybe put the truck on jackstands and...

    Low hum noise on 4WD

    @Gnix, I'm not sure the lift would have changed all that much except the angle of the front CV axles, I'm unsure that would cause your noise but I wouldn't rule it out (my truck is factory height). However in regards to your random brake squeaks I actually replaced my front brake pad hardware at...

    Low hum noise on 4WD

    On occasion yes you will hear a little bit of noise especially when running at high speeds or during tight turns on dry pavement. These 4WD AUTO trucks have an electronically actuated clutch in their transfer cases, this allows some slip when in dry conditions so that the...

    New to me ecodiesel questions...coolant color and poor MPG?

    Yeah, that sweet smell is totally normal on cold start ups. It will be more noticeable when the outside air temps are low and the engine has to high idle for a few minutes. I'm not certain of the exact reasons but I believe it is the emissions systems compensating for a "running rich" condition...
