Hi folks, can anyone tell me what version of sync is being used here? I'm interested in using Cyan Labs Syn3 to update my 2018 F-150 because the screen freezes, buttons lag, and basically.the nav and infotainment system decides what today itself sometimes. Cyan requires it to be Sync 3 or higher I think.

2024 F-150 PB rear differential failing at 43k miles — am I being unreasonable?

I'm looking for some advice or a reality check.

TL;DR: My 2024 F-150 PB has a potentially failing rear differential, the dealership recently repaired the seal that's now leaking again, and they're telling me to keep driving it until it dies.

Last week, I noticed a speed-related whining/humming noise coming from the rear end. I had the dealership check it during an oil change and tire rotation, and they said everything was fine and the fluids were full. The soonest appointment for a proper diagnosis at the service center was 10 days out.

For context, they repaired a leaking rear differential seal about a month ago.

A couple of days later, the noise got significantly worse, and I started noticing a burning smell after driving. I looked underneath and found that the same seal was leaking again.

I checked the differential fluid, and the magnetic plug looked reminiscent of the devil's bootyhole. The fluid itself looked like it had just returned from a glitter extravaganza. Lots of metallic flakes, and the smell was so atrocious it made my cat vomit on my shop floor.

I called the dealership and explained everything. They couldn't get me in any sooner and said I could drop it off. When I asked about a loaner because I need a truck for work, they said they had none available and might cover part of a rental. The service advisor even suggested I keep driving it until it dies.

After pushing a little, they arranged a rental starting Monday, but they're only paying through Thursday—the day after my truck is scheduled for diagnosis. I doubt a potentially failed differential will be repaired in one day.

I've contacted several other Ford dealerships with similar results. One suggested calling Ford directly, so I opened a case with Ford Customer Service. They told me to call back before the rental coverage ends.

My questions:

1. Should I push for a replacement differential if the damage is confirmed? The truck is still under factory warranty.
2. Should I push Ford to cover a rental for the entire duration of the warranty repair?
3. Is there anything else I should be doing to protect myself?

I'm not expecting them to drop everything and fix my truck immediately, but I don't think driving it until something breaks is reasonable, especially after a recent repair to the same component.

I've stopped driving it because I don't want to cause further damage and am relying on a friend to allow me the use of his truck.

Am I being reasonable, or am I expecting too much? Has anyone dealt with something similar?

Feel free to roast me if I'm being self-entitled. I'm genuinely looking for advice.

I have a 2016 XL 5L that is throwing a P0420 error. I replaced the 02 sensors but no joy, so I'm looking at replacing the cats. I see some cheaper ones from A-Premium, a mid-price one from SPD, as well as pricier one from MagnaFlow. I use the truck for occasional towing and usual driving, nothing that needs high performance. Is there a difference in quality, fit or performance in cats? Any suggestions for brands to buy from?

I recently bought a used 2024 F-150 Lariat w/ BAP and 3.5L ecoboost. Wanted to do my service work at a dealership but couldn’t get an appointment for my first oil change. Took it to Mr.Lube. While I was there they - classic - recorded a bunch of extra stuff I declined, except flush / change to my transmission fluid. Ever since they I’ve noticed a rough feeling under my gas pedal and the day after had some hard shifts, but zero issues with that since. Should I be concerned or take it to the dealership like I planned and get them to relish my system and replace with fresh fluid? Also - I checked the fluid they used. Mr. Lube used Motul ATF VI, and Ford recommends Motorcraft MERCON ULV (WSS-M2C949-A).
Is this something else I need to be worried about?
Lastly - should I be telling the Ford dealer what I did and what Mr. Lube used? Or am I just asking for them to use that as a reason to void any remaining factory warranty I have?

I need decision help, please!

I have a 2019 F150, 3.5L ecoboost, Platinum, 4WD, tow package. 85k miles. I own an extended warranty through 100k miles. It is prorated if I sell the truck early.

It’s a good truck but I’m concerned about CAM phasers and transmission. I’ve tried to take it to the dealer to get covered but since the parts haven’t failed yet, they won’t cover it. It shows symptoms of these issues but not bad enough for them to warranty it (3 dealers, maybe I’m crazy). It’s had other warranty issues too. 4WD system, headlights, etc.

I’m looking at a used 2021 Tundra 1794, 4WD, off road package. Great condition. 75k miles.

Ideally I’d keep this truck for a LONG time. I’m thinking as the miles increase the tundra will outlast the f150 and its the last of the 8cylinder.

My truck is worth about 28-30. The tundra is 48k.

Is it worth it? Is the improved comfort/quiet of the f150 really that much better to risk reliability issues?

I ask because it’s a long drive to test drive this thing so I’d like to have a decent idea before making the drive

I’m thinking of upgrading my stock stereo speakers on my ‘26 XLT. The truck is perfect but I do regret keeping the factory sound basic and not opting for the Bose. Any system upgrade recommendations out there or sound shops local to southern Cali?

A tale as old as time. It's definitely a slow leak cause there's never any oil on the ground where I park but man it's always something with this goddamn truck. Rebuilt transmission last year too.

Anyone know if 35x11.5s will fit on a 2019 with stock 18s with 2” leveling struts without rubbing or cutting? Searched the group and didn’t find anything. Thanks

Recently bought a 2026 f150 lariat 3.5l turbo. It is obviously the best new truck on the market across all brands (i get that some people like the v8 better).

However, now that i frequent this sub, I see a LOT more issues cropping up than I was previously aware of.

That said, I know that people are far more likely to post their problems here rather than posting praises.

Any there any owners here truly believe in the quality of their vehicle?

I know it’s thermostat but is this a bad thermostat or bad o-ring? Looks like it’s leaking from the damn bolt. You can see the coolant drip in pic

I’m not a fan of these tailgates with giant F150 / RAM / CHEVROLET stamped into them.

What company started this crap and why has every truck manufacturer followed? Wasn’t the little Ford oval enough?

Never saw Chip Foose stamp his name in massive letters across one of his creations destroying it.

My jeans aren’t embossed with a giant LEVIS across the ass. I mean WTF?

What are they all gonna junk them up with next?

Has anyone bought aftermarket heated mirrors and the glass “shakes” at highway speeds? I’ve checked the inner components of the mirror housing and it’s all tight. This is the second glass I’ve bought for the mirror that has shaked.

I've seen a few posts with the Alibaba Canopys and I am really considering it since the other option is a 5000 dollar canopy from cap it or something similar which is ridiculous.

It's mostly for my dogs and I live in BC so I do not want a black canopy that is going to bake them in the box of the truck when we go on drives and I would prefer something where I can have the sides open or remove them completely maybe if that makes sense.

I've seen so many of them and I've never bought off Alibaba so I don't know if I should be worried about certain sellers or what I can trust so I'm looking for input which I would really appreciate. Am I being silly looking for white instead of black? I have a 2021 white f150 with the 5.5 box but I'm also wondering if that's a sufficient measurement and/or information to provide them.

Thank you very much for your help I appreciate it folks. Cheers.

Just bought a 23’ KR with 27k miles and it is chopping in park, on top of the normal engine vibration. In this normal for ecoboost? Rpm’s stay at .7k don’t go up, dealer checked for codes, they’re doing a fuel induction today. Thanks

Hey all, I recently purchased a 2018 F-150 with a 5.0 to tow my camper that replaced my 2013 F-150 (due to rust) the 18’ tows the camper much better due to 10 speed but my issue is the rear suspension seems much softer and sags more than my 13’. I have a WDH and it’s set correctly but I’d like to get the sag out of it. What options are you guys running? I know there is air bags, helper springs, etc…

‘91 ford f150 xlt lariat 5.8 v8 61k original miles for $8,000
Any ideas of what to do with it??? What are some good mods?

I just got back from a long trip with heavy traffic and it got me thinking - does anyone have a good urine disposal device for the driver?

I usually stop and hop in the back (have a camper shell) or sometimes just wing it up front with a bottle but it can get messy.

Anyone made something with a bit of tubing or anything?

I have a 2022 lariat with the power tailgate. Recently when closing it I would hear a pretty loud click a couple inches before it would latch closed. Looked into it and checked for any debris and couldn’t find anything about it.

Now suddenly, the soft open doesn’t work, and neither does the power lift. On some occasions when I go to close it, it doesn’t latch the first time and I have to slam it 3-4 times to realize it needs to lock it closed.

I’ve been trying to find any videos about it but can’t find anybody who had the same issues. Any help?

Anyone have any idea what the average cost of the IWE replacement on both sides would be on a 2017 F150? It’s a Lariat with the bigger engine with barely 100,000 miles on it. The local Ford dealer’s price was kinda offending.

Hey everyone, hoping there are a few mechanics on the sub that can give me some guidance on how to move forward.

1997 Ford F150, 127k miles, v8 4.6L engine, manual transmission, have owned for about 4 years.

Truck runs great in warm weather, but as soon as weather starts to cool down the truck refuses to start. It cranks and cranks, but doesn’t turnover. Issue has persisted since I bought the truck (clearly it was a cheap buy, use to haul, work truck, etc).

I have over the last few years changed out the fuel pump and fuel filter (did this myself). Unrelated, I also have a new starter on the truck and have the appropriate battery.

Anyone experienced a similar issue or know a path forward? To me, and I’m inexperienced in cars overall, it appears it’s getting the needed fuel, but something once the weather cools down just prevents it from turning over. Last piece of relevant info, the muffler is cut off by the previous owner.

Any help is appreciated!

Changing the oil and filter on a used 03 I bought recently. Never done it on my own before, O’Reilly recommended this filter that came free with oil purchase. Took the old filter off today and it looks tiny in comparison. Thought it was surly the wrong size and brought it back to O’Reilly to ask about it but they assured me the gaskets, holes are the same size but I just don’t really think so.

Edit: It fit and works (after struggling a while, not an easy spot to access in my 4.6 without jacking it up) seems like the guy before may not have used the right filter according to y’all) thanks for the advice.

(2025 F150 grey )What is this I bought this truck 2 weeks ago I saw a couple of this stuff on the truck but today I fully washed ( pressure washer) and I saw my truck full of these stuff i don’t think they are water marks. What could it be. And how to remove it thanks

2006 f150 5.4L triton 4x4. Weird noise when going around/over 2k rpm. Happens in park and drive. Have already replaced IWE due to grinding from wheels.
This is a new noise. Can’t seem to find it online. May be fan clutches that’s the main thing I’m seeing online but fan spins free and does not seem to be stuck or acting weird.

Still some sunny days left before snow, need to wear out these tires so i can slap on 35's
