Just hit 60k miles in my 3.5EB and figured I'd change out the spark plugs. Really straightforward job. The original plugs looked pretty decent, with minimal ground electrode wear and only ~.003" increased gap over the brand new ones.
I find winter blend gasoline to drop MPG a bit, also check your tire pressure. Mine were 6-7psi low when I checked them the other day and I noticed a 2mpg increase since airing them back up.
My 2021 has only had 1 recall I had to take to the dealer for. The wiper motor one, but it was already there for the max tow axle bolt issue. Others have been addressed via over the air updates.
Purchased my 2021 in April 2021. 3.5eb 157" wb 4x4 max tow, right at 60k miles now.
I've had an exhaust rattle from the resonator, fixed by adding a Corsa exhaust.
Rear axle hub bolt broke around 50k miles (which is super common with the max tow package)
Air bag clock spring started making some...
I put the same Corsa system on when it came out in June of '22. It was a little louder than I really wanted so I put the Corsa resonator on as well.
Mine is the 157" wheelbase so I just cut the extension pipe before the muffler and put the resonator there.
I have a 2021 F150 XLT 302a and it sounds like my clock spring is making noise when I turn the wheel. It started out quiet and keeps getting louder. The truck is out of warranty with 60k miles on it, so I'll just replace it myself.
My issue is there are 3 versions available and none of them...
Forgot to update this thread. I found GTR Lighting 4257 bulbs from The Retrofit Source fit great and work well.
And for the hyperflash, it flashes at thw regular rate outside the truck but only the turn signal indicator inside the truck flashes quickly. If that bothers you, you can use forscan...
VLEDs told me their 4257 bulbs would fit but they were too wide for the socket. Could have filed them down but that would've voided the warranty if I had any more issues. Ended up returning them.
We're talking 200 lb max tongue weight since its an unloaded open car trailer. Tires were the 20" hankook dynapro atm before and a 18" Goodyear wrangler territory AT now, which looks more aggressive and holds more driveway gravel than the hankooks did.
That's what I mean. It's really strange when it happens. Like a clunk where you can tell and the rear tires have broken grass in the tread for 1/4 of the tire from that slip and the fronts have none. Never had a truck do that before this one.
