    Found my rattle

    Could be a leaking/broken exhaust manifold or bolt. Common problem unfortunately.

    ecodiesel driving experience

    This is my first diesel engine. I have had a few 2019 and 2020 RAMs with Hemi's. I do not miss them one bit, and have been loving the EcoDiesel driving experience. Engine sounds great, MDS is gone (I never hated it, but didn't enjoy it either). I don't care about not having eTorque/stop/start...

    Tonneau Cover Questions

    1. No. Engineers do plenty of testing for aero. And as someone else mentioned (though I haven't looked up any studies specific to tonneaus), there is actually less drag when air molecules flow past other air molecules (i.e. the air flowing over the truck and over stagnant air in the bed will...

    Audio Advice / Help Needed: Rear Headliner Speakers

    You could do higher ohm, or less efficient speakers in terms of power handling. The sub shouldn't be getting any more power, but who knows. The amplifier/tuning for the subwoofer is GARBAGE. If you want anything to sound decent, just unplug the sub. The 6x9s do just fine on their own with the...

    My truck will be sitting dormant for 7 months

    Welcome home brother. If there's a next time, I'd recommend doing a little prep work for anything more than 2 months! On my deployment a few years back, I went to the closest fuel station where I was going to park the vehicle. Added Sta-Bil to the tank (not sure what a diesel equivalent would be...

    Limited Leather dash delamination.

    Tint on the windshield will help slightly, but not worth the cost or hassle IMO. You are much better off using a full coverage dash shade when parking outside in warm weather. The dash getting extremely hot in direct sunlight when parked is likely the causal factor here. Huge temperature...

    2021 eco diesel gas mileage

    Unfortunately this TSB has been a bit cryptic. Normally they specifically show a date range of affected vehicles, and so far I haven't seen that within this TSB. The only document I've seen is dated early December 2020, so one would assume any truck after that date is fine, but that may not be...

    Check engine light on new vehicle

    Hah, that'd be great, but dealers have 0 need to give away anything right now. If I don't buy it, someone else will.

    Check engine light on new vehicle

    Different cause but same situation on my end. Went yesterday to look at trading my '20 HEMI for a '21 Ecodiesel. Turns out the truck died on the GM while driving (he was going to use it as a demo for awhile, but it had <100 miles before this happened). Got word this morning they hopefully found...

    Air conditioning Hack

    And this right here is why I'm hesitant to have it done. It's an intensive job. If the tech isn't super careful, **** will get damaged or broken. The fact he (or the service manager) didn't man up and admit fault is pitiful. They need to go work at McDonald's instead.

    Bad fuel mileage 5.7 hemi

    Don't trust the computer readout. It's frequently 1-2 MPG optimistic. Hand calculations are your best bet. And no, MPG doesn't really go up. My 3.21 5.7 eTorque has a fairly flat line in regards to its lifetime MPG of 17.7 (nearly 10,000 miles). I drive pretty conservatively too. The computer...

    Does the cleaner itself have a scent/odor? Hopefully not, but may not be avoidable...

    89 octane recommend, does it really make a difference?

    It adds 15 seconds to the process if you are quick about it and use tap-to-pay on a Costco Visa card. I couldn't give a **** less what the person behind me thinks. If they're mad, tell them to call Costco and request they implement a mid-grade button. Going to the station 2x as often (because...

    Harman Kardon Boomy Bass

    You can disconnect it at the amp under the driver seat, but you need the pinout diagram to know what pins to remove from the wiring harness. Crutchfield has it in their research doc, which you should be able to find online. There's also some posts on here detailing how to unlatch the wiring pins...

    89 octane recommend, does it really make a difference?

    Probably not. I've never noticed a tangible difference. And my mom has run 87 octane in her 2009 Aspen w/ a Hemi for over 300K miles just fine. Data logger may say otherwise, but even in terms of knocking and MPG... my truck runs seemingly the same on 87 as ~90 (93/87 50:50 split). I fill up...

    A/C Performance

    If you're referring to the Mopar extended service contract, it's highly unlikely it will cover a TSB repair. As long as everything is functional, they have no reason to pay out a claim to improve/update your HVAC to the current revision. Your best bet is to point out that you had the issue under...

    Adaptive Cruise Control.....Yay or Nay?

    Worth it? Yeah, I'd say so. It's a nice lazy feature. But the feature itself is lazy (seemingly moreso than other FCA products I've owned)... meaning, it drives me mad how slow it is to respond to changing situations, and the range is pitiful. Seriously FCA. A full redesign with all new hardware...

    Limited Leather dash delamination.

    Can we get a photo? Curious what that looks like.

    Rear Cab Wall Vent's

    Without recirc mode on, yes, because the blower won't be able to push nearly as much air. Think about it. You left open 1/8 of what was designed for airflow purposes. If the cab didn't ideally need that much, the engineers wouldn't have made the vents that large, nor made 2 of them. My sound...
