Sport mode 4wd steering pull

[Blackscreen67]

Does anyone have a steering pull when accelerating in sport awd mode?

Mine has a hard left pull that gets worst as rpms climb past 3k.

In 2wd normal mode it' fine.

Tires inflated correctly? And I don't mean checking using the onboard TPMS, wheels aligned?


You will get some torque steer but I actually found it less in sport/awd than normal/2wd

All tires are good psi wise, and alignment is true.

It's without a doubt a power distribution issue.

Had my original sales guy ride with me and he saw it pull the wheel while in sport mode accelerating.

Pulls as if the left front is over powering the system badly.

While he was in the car and open road. Did a light acceleration rolling from both a dead stop and at hwy speed. As soon as power comes up it instantly wants to go left. I took my hands off the wheel on a flat section of freeway and no cars around and jist lightly let rpms creep and could've crossed 2 lanes of traffic in no time.

We got back to dealer, hopped in another 4wd limited.

Had only 3 miles on it and drove it like I stole it and it stayed true in both normal and sport.

I’ve never experienced this.

I'm starting to think mines a 70k lemon!

This sound is after it had already warmed up, and remote started.... 30 miles on the clock.


Bought it with 4 on the OD....

How bout this sound?

Mine has made that rattle on startup since I picked her up with 6 on the odo. I don’t love it but I asked the dealer about it and got a shrug.

The thing that bothers me isn't the sound, it' that it does it inconsistently.

I mean loud enough to drown out the exhaust sound.

It's not injection "clatter", that I know 100% because it'll fade in and out then go away.

My sales guy said "it's because it's twin turbos"....

I tilted my head like a confused dog and said..... all my cars are twin turbo and none sound like this.

That still doesn't top when the sales manager told me the front left pull is because its really only spinning 3 wheels and not true all wheel drive....

I was speechless!

Mine does it every time on cold start. I have always assumed it was injection clatter you described as it goes away after ~30 secs. But yes, it is louder than the exhaust.

Solution: don’t start your vehicle before you get in as the truck’s awesome sound insulation will mask it. Haha

In the video listen for the flutter.... Like a baseball card in tire spokes. I think we're talking 2 different sounds.

Personally daily driving a highly modified diesel I'm used to clatter and embrace it lol. The first time I head the noice im talking about I nack away from the vehicle not knowing what was happending.

Haven't been able to duplicate that level of the noise since, but same sound.

Some of the gen 2 ecoboosts have been having issues with knocking and ticking. Yours does not sound like either example.

Sales manager is full of crap, if that was the case then you’d have everyone in this thread saying that there’s pulls to the side as well. Also, that noise isn’t something mine does either, I do get a tiny bit of flutter on cold startup but it’s over within seconds. This almost sounds like a exhaust gasket leak, especially if it’s constant and doesn’t go away. Maybe you should consult a second dealer.

 

[JohnT]

Mine makes the same sound for about 20 to 30 seconds, it almost sounds like a variable exhaust or an interference fit collar on the exhaust letting gases blow by until it warms up.

what happene if you put it in sport mode, then manually put it back into 2WD, I do this on the highway. That may isolate it to the transfer case or front drive axle

Honestly it does it at any speed. I have done the switch while on the highway though, and it is straight as an arrow after switch back.

The pulling issue could be as simple as a hub not engaging, probably on the right if you’re pulling left. That does not mean it’s a simple issue to fix, especially if it’s an electronic/ computer issue. There are other potential causes, but I’ve actually experienced the pulling with problematic hubs. I guess the question I have is does it only do it in Sport Mode? Or does it do it in any mode where the Expy is in an AWD/4WD setting?

As for the noise. That’s just not normal. Not sure if the problems are related or not. Your dealership seems to be jerking you around, which is also not normal. It’s not like Ford doesn’t pay them to diagnose and fix these issues. If they can’t get it fixed, get a second dealer’s opinion or see if they can fix it. Next step from there would be to declare it a lemon and tell them you want a new one that isn’t broken.

This is from about an hour ago exchange between my sales rep and I.

I'm done, and told them they can keep the car. Nor did I ever take them back the title on my trade since I only had the car for 2 days. On the 13th and 14th.... they had it the rest. I never tried any other settings except sport and normal.

To top it off not one of these things did they put months vin service record, nor outlined any fix to the original issue.

I have seen several issues lately that involve what I call radial tire pull. It may be the issue and may only occur while 4WD is engaged though the instances where I have seen it happen involved front tire on 2WD vehicles. It is simple to diagnose and only involves rotating the tires left to right and see if the issue changes sides or disappears. Here is a short article and it is ashamed that mechanics today are not taught more about diagnosing issues.


Release the steering wheel and the vehicle veers to one side. Most people think first of a wheel alignment problem. Surprisingly a tire can also cause our vehicle to pull. Tire conicity is a common phenomenon even in new tires. Many people also call it a "radial pull" and sometimes a "tire pull."

What is tire conicity?
Tire conicity is where a properly inflated tire causes a vehicle to pull to the right or left when driven. Tires do not get conicity. They manufacture them with the tendency. It is considered a defect and tire manufacturers cover tire conicity under their warranty, if we diagnose it properly and promptly.

Does the on board computer show any issues with power distribution in 4wd? On my 2016 one of the displays shows power distribution.

No it didn't. It's really unfortunate because the one we have back was perfect according to my wife.

We went and looked at the platinum interior with ceramic before I finalized a new deal for her and she hates the ceramic compared to the stone the limited had.

Then I would lean towards it being the hub. The computer thinks it is routing power to that wheel but you aren’t getting power there. It isn’t locked up so probably just not engaging. Should be a warranty repair.
