    ROLL-UP INFO: FOTA 18.11.x & uC D/L 18.45.01 SW Update 13-17 RA3/Vp3-NA & Ra4 VP4-NA

    I didn't complain about mine or called them. I'm thinking its just taking more time than they thought to update the database... perhaps they found that they have to go through it manually.

    ROLL-UP INFO: FOTA 18.11.x & uC D/L 18.45.01 SW Update 13-17 RA3/Vp3-NA & Ra4 VP4-NA

    UConnect had been saying my 2016 RA3 with Nav update was up to date at version 17.11.07. Nav server 9.10.32.682628. For grins yesterday I checked and now indicated 18.45.1 was authorized. Perhaps there had been a authorization issu? Anyway, I have a Mac, where I downloaded the update, double...

    ROLL-UP INFO: FOTA 18.11.x & uC D/L 18.45.01 SW Update 13-17 RA3/Vp3-NA & Ra4 VP4-NA

    So let me get this strait, for my own edification. There are two updates going on, the first is to fix the GPS roll over issue (I'll call that GPS firmware). Its the one being automatically pushed everywhere. The second is the full software update to 18.45.01 or 18.50.35 depending (which may...

    Is Uconnect Nav worth the ridiculous cost?

    Navteq and some others morphed into HERE a few years ago. Garmin has been using HERE maps for a couple years now. They are not nearly as good as the old Garmin, lots of complaints. Google has their map data base. TomTom I believe still has a maps data base, also used by Apple. Perhaps also...

    UConnect update?

    I have the OEM 2016 RA3 unit PN 68249986AI that I paid to unlock the nav. Its been working fine except it tells me I'm I've reached my home destination about a mile before I actually get there. A couple days ago I saw the update pop up as I started the truck and scheduled it for about 1 AM...

    4wd grind with open diff?? I feel like a noob on this

    4WD will bind (wrap up drivetrains) because in a turn the front axle spins more than the back (has to travel a slightly longer arch) but the transfercase has locked both drive shafts together preventing them to rotate at different speeds. It doesn't matter if you have locking diffs or open. On a...

    Anyone HAPPY with Borg Warner 44-44 / Auto 4WD

    Unlike some other transfer cases (like the MP cases Jeep and GM use) there is no partial engagement of the clutch pack, its either turned on or off (connected or not). 0-100% is done entirely mechanically via the ball ramp. The more the ball ramps up the more torque gets transferred. Wether it...

    Anyone HAPPY with Borg Warner 44-44 / Auto 4WD

    I wish I could find the document I was reading back in September. May have been on techauthority. I do recall that there were some differences between years, I was looking at 2016. So tell be again what is the difference between 4Auto and 4Lock besides the indicators that light up on the...

    Anyone HAPPY with Borg Warner 44-44 / Auto 4WD

    In 4WD auto, one of the two half axles is split (disconnected) until the computer thinks it needs to power the front wheels. In 2WD its always split. In 4WD lock, the axle disconnect is locked in, thats why RAM calls it the locked position, not that the transfer case is locked. Thats why most...

    Anyone HAPPY with Borg Warner 44-44 / Auto 4WD

    I think the variation in clutch pack preload due to production tolerances (or even running changes) would have a much more significant effect in the 44 style case. I think slightly larger tires on the front may kick the clutches in earlier and firmer, once there is front wheels spin or when...

    Autopark while backing (too fast)

    I got one for my 2016 the other day, and am reading through the thread to see if I want them to mess with it.

    ABS Issues

    Did you read the ABS codes with a scanner that can read them? Otherwise you may want to disconnect and reconnect the sensors to scrape off any corrosion. You may want to look for poor connections or shorts elsewhere in the harness. You may want to pull the sensors to see if they are dirty with...

    beware the scehduled maintenance service "recommendations"

    Its worse than being fleeced as most of the FCA service manuals say not to do these types of cleanings as they do more ham than good. So they are damaging the vehicle along with fleecing you for profit. They have no intention of improving your ride or longevity. The ratings may work as when I...

    2010 Cummins, 105,000 miles

    I had a 2006 Megacab, before the problems introduced in 2007. Biggest issue then seemed to be the few where a leaky injector washed oil off the cylinder wall. Lots of potential $$$ there. It was a manual transmission, seemed to be able to pull a house off its foundation idling in 1st. It did...

    4wd auto shifting

    Does the transmission have a different shift program based on 2WD vs 4WD auto mode. It doesn't shudder in 4WD lock?

    Intermittent trouble code

    The Evaporative Purge Monitor tests the integrity of the hoses/tube between the throttle body/intake and the fuel tank. If the PCM detects that the purge vapor ratio and the ESIM switch closed ratio are below a calculated value, the PCM commands the purge solenoid to flow at a specified rate to...

    Tpms has me stumped

    Does the TPMS indicator flash for a few seconds and go solid or flash for several seconds before going solid? The sensors have a radio transmitter and when batteries get weak, the signal weakens. Sometimes the computer picks it up, sometimes not. When it doesn't pick up a signal, it sets a...

    4WD Lock or 4WD Auto?

    Just a correction to my post above, for whatever its worth. The lock position does lock the front axle haves together and applies a bit of preload on the transfer clutch pack. Not full lock, but provides quicker torque transfer than the auto position. Auto seems to wait for wheel spin tp be...

    Help, need an OEM radio with code, can't unlock mine

    The VIN and radio SN are used to create the anti-theft code for most recent FCA radios which is then verified by the PCM of most vehicles. A code from a radio removed from a different vehicle is not going to work. You either need the original code, or have someone generate the code from the...

    "Limited Slip" vs "Anti-Spin Differential Rear Axle"

    Limited slip works better in a number of situations, there is a thread around here somewhere. It doesn't need as much power to operate and can be driven with more precision. Traction control augments the limited slip rear axle at higher speeds. Front axles don't have limited slip. so it depends...

    2018 Ram 1500 service manual?

    I had alldata years ago for our Aveo. It was basically a scanned copy of some version of the factory service manual. It seemed to be accurate and complete data. Dunno how they get the information now as the FSMs are all no longer published, everything is on line. The FSM CD that you can get...

    Har folding tonneau cover

    After about a year or two hard use, my BakFlip leaked like a sieve at the hinges with just a little rain. I had to use tarps under it to keep things dry. You will see many reports of this. The BakFlip has many nifty features but water tight over time is not one of them. I've been using the...
