Resolved: Grinding from Left Tire on brand new Lariat Tremor

[Pinbalz]

Brand new Lariat Tremor 126 miles took to dealer for grinding from left front tire when backing up to right out of driveway. In and out of dealer quickly same day. This is what the result was…a frame protection plate was misaligned and striking tire only when backing up. Did not hear when driving forward at all. Dealer did not charge.

Chassis Ears? Is that a slang term for some special tool st the dealer?

A device with microphones to listen for noises from what I understand to locate noises during a road test. Never saw heard of that before either.

Thanks for posting this. Mine does the same thing, but sounds like the right side.

Now I need to find the "frame protector bracket".

I assume they mean the crash intrusion bars.

Other Tremor owners have complained about this as well.

You can just loosen the bolts and press it forward, then retighten.

I had the same issue on my tremor. While I was replacing the fog lights I took the opportunity to push the crash bars as far forward as they would. They didn't move much, but they did move. I haven't had the issue since.

Brian,

If they’ve only angled your anti-intrusion beam (crash bars) out of the way, as @Aonarch points out (I suspect he’s right), and as @HarryManback did, it only provides an additional 1/4” clearance at best. You might still experience “rubbing” at full steering lock under front-end compression. You won’t experience it under most driving conditions but while off-roading, braking while turning sharply, turning into a steep driveway, etc., it could be present.

Go do some aggressive 3-point turns or just maneuver back and forth aggressively at full lock in each direction. This will compress your front end and you’ll know if they solved the issue or just kicked the can down the road a bit further. If it’s still not rubbing, feel good about it. If it is rubbing, welcome to the world of tire height, wheel offset, and amount of lift.

There are ways to solve this but I bet you a beer your dealer won’t want to perform them. Good luck with this. ?

It is an actual tool in the automotive industry. I have used two different styles. Ford is nice enough to give you a wireless version which is great. There's also a wired version and it's a pain in the ass to use.

Many times I have posted about using a Mechanics Stethoscope. Chassis ears are an electronic version. My NVH engineer had a pair of a very expensive pair of "ears" that was a bit more sophisticated than the poor man's mechanics stethoscope, but I could use my pair of them and beat him to the punch over the $10,000 electronic ones. I even tried to use them first and resorted to the mechanics stethoscope.... We did not have wireless back then...maybe better. I am glad the dealers have much better NVH tool now!

Best,
Phil
