Paging F150 Mechanics - Update in Original post.
Posted on 1/23/17 at 9:08 am
Posted on 1/23/17 at 9:08 am
I have a 2011 F150 4x4 that has started making a low growling noise. It's not constant but I really noticed it this morning like it's getting worse. I switched to 4HI this morning going straight down the road to see if it would change anything and the driver's side front end popped a couple times. Again, I wasn't turning. Any ideas? Could it be the IWE's going bad? Vacuum solenoid?
It's got 112k if that helps. Thanks.
EDIT FOR UPDATE: Mechanic found a vacuum leak in the line near my driver's side front hub. It wasn't getting enough vacuum to fully disengage the hub so sometimes it was still engaged, sometimes not. Replaced the vacuum line and all is good. Thanks for the help!

Per post in this board, timing chain.

This if you have the Ecoboost.

It would be helpful to know if it makes it in gear. At what speeds? Does the sound change (pitch) when accelerating or coasting?
Posted on 1/23/17 at 9:35 am to ducksnbass
The 4H on those more or less act as a AWD system, meaning all 4 wheels are always searching for traction but the most power is sent to the tire that has least traction. The popping in 4H is normal
Ecoboost or 5L?

Sorry, that would help. It's the 5.0L
I only really notice it at low speeds, Example, I noticed it backing out of my driveway this morning, (long flat driveway) and driving on my street. 15 mph or less. Not sure if it's doing it at higher speeds, I have BFG KO's and flowmaster exhaust so it's kinda loud on the highway.

I have 2011 V8 F-150 and I swear everything that can go wrong with it has. Right at 100k and I don't think it will last much longer. What is it with this year model?

No check engine light or anything?
If not, could be a hub issue.

Nope, no engine light, no light of any kind.

Posted on 1/23/17 at 10:35 am to FishinTygah84

I had the 2011 Ecoboost and right at 80K things started going bad. The timing chain sounded like it was going to blow up every morning. Glad I got rid of it, but it sounds like they got things worked out on the newer motors. The 11-12 motors were still new so they had some kinks to work out.

Mine is a 13

Is it also lifted? If so that can put a lot of pressure on the front drive axle shafts and joints.
Like someone said it could be hub bearings. A good shop can put chassis ears on it and maybe able to isolate the noise.

Well maybe they didn't work the kinks out. How many miles do you have? I know some people said they were covering the timing chain on the 80K emissions warranty.
Posted on 1/23/17 at 11:10 am to jdavid1
60k warranty, not 80. I'm at 107 and from what I've read they're still seeing issues up to the new 2015 models
Posted on 1/23/17 at 11:22 am to PapaPogey
Damn I thought it was 80. That sucks. Glad I went with the 5.0 on my new one.
