Hi all New to this forum

I what does it mean when my rapping noise in the front of the motor changes to a rap rap rap screech noise?

 

welcome to FTE without hearing what the noise you ask about we can't help you,, make a video of it,post to you tube since you say you have a 2013 make a post in https://www.ford-trucks.com/forums/forum193/ asking for help
and that you will get a lot of

 

To be blunt I am afraid to run it.

 

we need to hear what it sounds like, otherwise the only advice is have it towed to a shop ,

 

normally to help we ask for
year of the truck
model
engine,trans,

without being knowing more than what your user name tells us 2013 f150 3.5 ecoboost , and not able to hear what noise you are asking about, the many dealership master techs and a few factory engineers, in this forum have zero information available,that can better help you. as "noise from the engine" is meaningless, could be simple a bad belt idler, or deeper and very costly timing chain issues, engine bearing issues due to lost oil pressure, there's a large list of items that can make rapping noises
that leaves only 1 logical thing to tell you,have it towed to your local dealership or trusted repair shop

 

It means something bad happened. Like @charlie g said, we can't tell from what has been described so far what caused the rapping sound and what caused the screech. If I were guessing by probability, this would describe your air conditioning compressor seizing up. If I were a pessimist I'd guess the engine seized when a piston turned sideways or something. Somewhere in-between I might guess an idler pulley lost a big chunk, ran as long as it could, then seized. There are maybe a dozen other issues I can think of off the top of my head that might fit this description. If this is a 2013 F-150 3.5TT with 150,000-199,999 miles on it that is getting driven between 50,000 and 74,999 miles per year, I'd guess it's sudden drastic increase in workload might be related, especially if all these additional miles include towing or hauling.

Probably a good instinct!

As for next steps, your best bet with us would be to start a new thread in the 2009 - 2014 F150 forum describing the issue and including the year, make, model, odometer, and anything else you think might be helpful such as recent surgery and damage, how the vehicle gets used, and how many miles you've owned it. This will help the folks in that forum to better understand the symptoms through their screens and keyboards from the far side of the Internet.

Welcome aboard!

 

 

i would start by checking the idler pulleys and water pump, as it's more of a bad bearing noise than a deeper engine .does removing the drive belts stop that noise?

 

Opening the hood and inspecting it coming from the front right side bank area near the top of the motor

 

remove the drive belts does it go away?

 

Dunno it was towed to the stealership this morning

 

Well I feel sheepish


It was the waterpump bearing

Kid that picked it up with the tow truck said thats what it sounded like to him

 

please don't feel that way, we all try to help as best as possible, that noise to this old tech sounded roller bearing like from the water pump. belt idler, alternator , just which one not being on top of the motor from nj i couldn't help only try to advise
please let us know what the dealer tells you

 

They also told me I had a bad pass side front wheel bearing which has been 2 years since they told me last time they checked it out. And two front strut springs are broken. Turbos leaking oil, amongst other things

/shrug they want 1600 for the struts my local guy is at 1100 same job...

 

hear the new we did a free safety check for you and found hoping to drive up the costs, you have the right to tell them to pound salt ,take the truck to your local shop, 1100.00 the struts sell on rock auto loaded with new springs for under 100.00 each
