So your saying that Ford engineers are wrong and your right?

The spec is 150lbft, exerpt from the Ford shop manual. Bottom of page.

I have never put a torque wrench on a lug nut. I drag race, have muscle cars, and can not even remember how many cars and trucks I have owned. Never had any issues. I also have personal friends at the dealership and have never seen them put a torque wrench on a lug nut there. They just zip it on with the impact.

Just because you and they are halfassing a procedure does not make it right. Every time I take my wheels off, they get torqued back on and rechecked after 100/300/500 miles.

Why?

The factory lug wrench is a joke if you're trying to remove the lug nuts after the gorillas at the tire shop torque them on with a 24" breaker bar and a 6' pipe for a cheater.

At least I'm assuming that's what they do. Last time my air impact gun couldn't budge those sons of guns, and I thought I was gonna have to put a cheater on my 24" breaker bar.

An impact is the absolute worst way to put lug nuts back on! I get why shops do it, strictly to save time. They also know they won't be held accountable when that lug nut needs to come off next, if anything they'll get more guaranteed work when the stud is pulled through the hub.

Because I've seen cast wheels where they were distorted around the studs from being that tight.

Haven't actually tried on this truck, but I always used a 200-250# weight to loosen lug nuts with a factory wrench if necessary. Hasn't failed yet. Never did calculate the torque value of this process, but it seems to be high enough.

Uh - Yes. They are concerned with the liability of a wheel coming off, and if the bevels around the lug nuts are wallowed out, why would they care - they get to sell a replacement wheel.


The also recommend anti-seize. How many of you guys do that, which would only encourage a nut to loosen.


Engineers learn from people in the field all the time

Wouldn't shredding a wheel at those holes also cause it to fall off and be a major liability issue? And then why aren't all car models specced to 150?

Not really related, but two vehicles have had a wheel come off on my street. I only spoke to one of them, he said "I know I put it on right". Uh huh, sure.
