Yeah, whoever designed that control to close so hard you can feel it in the cab needs to go back to school.

So in other words. This is how they built these model year trucks. It's too involved for a TSB, so deal with it, fix it on your own or sell it. We really don't care!

Pretty much.. they created clunk.. and they don't care.

Once again, adding tech to the vehicle is causing issues. We never had auto flaps years ago and the trucks worked just fine. If these auto manufacturers got rid of stupid crap like this, active learning transmissions, lane departure/active cruise control, etc, we'd have so many less potential issues.

Let's just go back to a nice vehicle with power windows/locks/steering/brakes/mirrors, etc, add in a good radio that provides SiriusXM, bluetooth and regular radio, and if you want heated seats, you get it from a hard switch, not software thru the radio and I bet these issues go away and people will enjoy their cars again.

They are trying to increase their profit margins by adding in more tech. Not only in the initial cost of the vehicle but also their service centers once warranty is up.
We make cabinetry for auto dealerships. The owner said it will soon come to a point where all vehicles will be leased with a maintenance plan as the costs for servicing continue to skyrocket.

Strangely simple fix to do, not sure why they don’t.

I'm new, if this is the wrong place to put this reply, please move it. I've been reading about F150 noises here since mine started giving trouble, so I am interested in others comments. I have a 2018 F150 XLT 5.0 10 speed 4x4 with 24,000 miles on it.

Last Feb it was -25F and I was pulling a trailer and the truck started making faint grinding noises. Let off the gas, the noise got quieter, step on the gas, louder. It kept time with the road speed, not the engine. It could not be heard in park. It needed to be going at least 20 mph to hear it. Early March I took it to the dealer. They said it was SSM 47812 whine noise and is normal. This noise is loudest in park. My noise never occurred in park. I paid for a transmission oil and screen replacement.

With driving the noise gradually worsened. In Early April I was pulling a trailer and smoke poured from beneath. The underside was dripping with trans fluid. The noise got worse too. I took it back, they said the pan gasket was probably leaking so they ordered a new one.

April 16th I took it in for the pan gasket replacement and complained about the noise getting worse. Keep in mind now, the noise is driveline related and keeps time with speed, not the engine. They said it was TSB 19-2093 bell housing noise and replaced a bunch of parts. The truck never had that bell housing noise. I took it home and 20 miles down the road smoke poured out again, and the underside dripping with fluid as before. The trans temp gage was at 236.

Here's the noise now as best as I can describe. At idle in park, none. In drive 0 - 20 mph, little noise to none. 20 mph - 40 mph a sort of grinding noise, not very loud. 40 - 60 mph a whirring noise as in: "whir - whir- whir" - the faster speed, the faster and louder the whirring. At 60 - 80 it's a high pitched whine that is very annoying and the trans temp soars and it pukes out fluid and smokes. Over 80 the noise is gone.

I immediately turned around and took it back. They have no idea what the trouble is. It's been in the shop 3 times and each time they said it was a problem that did not apply or exist.

Any ideas on what to do or what the problem is?

After reading this...my unit will not grace the light of day in a dealership, or if it does, there will not be any update flash business happening. Mine runs perfectly, and to think that a flash can induce other problems....I'm good the way it is now - thanks, over and out!

My truck is fixed. To reinforce your point, the dealership induced two problems it never came in with. The truck had driveline noise that kept time with road speed. The faster it went the louder the noise. Back off the gas, the noise lessened. This meant the noise was from the output part of the transmission, the transfer case or the pinion.

There was no noise in park nor did the noise change during shifting which ruled out noises from the engine to the input parts of the transmission.

The dealership insisted the noise was related to straight cut gears and normal, so I presumed it was the transmission and paid to have the oil and screen changed. They overfilled it which is why it leaked.

I took it back. They then said the problem was in the bell housing, pulled the transmission and replaced some parts. They overfilled the transmission again and did something they would not admit to that caused it to rapidly heat up. This did not cure the noise. The transmission leaked oil again.

I got real PO'd, and insisted they fix it. They then gave it to their lead mechanic that could instantly tell what the problem was by driving it. The rear end pinion bearings were pitted. The bearings were replaced and the noise went away. He said the other mechanics used the wrong dipstick to fill the transmission and did not say what they did to cause the heating problem.

After 4 trips to the dealer adding up to 22 days in the shop it's fixed. Runs great. No noise. We went camping on a 450 mile trip with a 4,000 pound camper and the temp never got above 197 degrees.

The mechanic that fixed it said he's replaced several pinion bearing sets on F150's that tow or haul a lot as the 75w85 gear oil is not thick enough. He replaced it with 75w140 as he does with all his repairs and the bearings last.

@ilander001 , was the noise louder at certain speeds? My truck has a whine that is audible between 50 and 60 mph. Above or below that, I can't hear anything other than tire whine and wind noise, but dead on at 50, a whine from the rear starts up. I haven't taken it in yet, but ring and pinion would seem to be the only logical thing. I have only towed once (a light weight trailer, for about 120 miles round trip), and this started well before that, and was not changed by the towing.

The user above you posted that it was his pinion bearing that was noisy. Not the ring-and-pinion interface. Your ring gear is more than likely fine, but I suppose you'll not know for sure until the rear cover is removed and the assembly inspected.



ilander, if you return, would you please post which rear axle is in your truck? Is it the 9.75 or the 8.8 Super? Thanks in advance.
