2013~2016 CX-5: They broke it again!

[ColoradoDriver]

Got my winter tires changed out for my all-seasons a couple weeks ago. Was a bit late to it because the house got COVID at the beginning of May.

Anyway, once again, Discount Tire broke off one of my studs, this time on the driver side, rear wheel hub.

This happened a couple years ago too. They at least pay for the fix with a voucher to Brakes Plus, but it's highly annoying. Last time I got it fixed I was there for 4 hours.

This time they say it's because the last shop to install my tires used the "wrong" lug nuts and apparently this one got cross threaded so it was going to break off. Funny for them, the last shop to touch my tires was a different Discount Tire.

Doh! Bummer

I've been a big fan of discount tire for years they have done really well for me. However, the last two visits I had and one my daughter (same store) had left some to be desired with the work of the "tire tech". I'll have to keep an eye on 'em next time and even request that particular tech not service my vehicle (if he's still around) .

Some people scoff, but this is exactly why I always use anti-seize on my lug nut studs. It truly does prevent cross threading, because you can EASILY start them by hand every time.

I started doing this like 25 years ago, I haven't lost a stud since.

Do you reduce the torque value on your anti-seized lug nut studs by 20-30%?

I set my torque wrench to 80.

Sounds like the impact gun was set too high. Happened to me a few years ago with my mini van. Got it back from the shop and a lug nut fell off with the stud in it. I always check the torque when I get it back from the shop. More often than not they're where I like them, around 85, but every once in a while you find a few that are really cranked down.

This kind of problem is why I prefer to rotate and change my own tires. I don't do it very often, so I think it's good to remain familiar enough with the jack, etc., so I can do it along side the road if I ever have a flat.
It is a bit of work but not complicated. Still, a mistake can cause a lot of problems. So I do my own tire rotations, oil changes, and anything else that isn't too difficult. I don't use an impact gun to tighten the lugs. Although sometimes I use it to make the job quicker I torque them by hand.

And yet, you took it back to them after they screwed the job up the last time?

I’ve always been told to reduce torque on lubricated fasteners or bolts by 20-30% because the reduced friction often leads to over torquing because of clamping force changes. One can go down a rabbit hole on the topic on a lot of engineering sites.

I like the labor savings of the impact wrench so I got myself some 80 lb ft torque-limiting extensions. I'll torque them to spec afterwards.

I think resistance is resistance if we're measuring torque, but I'm wondering if lug nuts with spinning seats have the same consideration. Nothing is stated in my McGard lug nuts box. Maybe I'll contact them and see what they say.

 

[Kedis82ZE8]

That’s not what I’ve seen related to torque. You can find lots of hits on the topic. I remember it came up while I was replacing head gaskets on snowmobiles in years past.

How the previous shop (another DT) used the wrong lug nuts as all nuts took off were sitting right near the tire removed? And you didn’t talk to the manager about this?

I’ve been using DT since late 1980’s and it happened only once to my 1998 Honda CR-V. Luckily I was watching the guy doing the tire installation, and he broke the stud when he was using the power wrench tightening the nut. It definitely is his fault. The manager first was sending me to a shop who refused to use Honda OEM stud and lug nut. Then I asked the DT manager sending me to the Brakes Plus who was willing to use OEM parts.

I’m still watching when DT is doing the tire service for me, although I have to be standing outside the the garage door nowadays.

Yes I do re-check the torque after any tire service from DT.

Different location.

Yeah I was confused by that as well. I said these are literally the lug nuts that come with the car, so what are you talking about?

Buy your own torque stick and make them use it.

 

[erhayes]

+1. When I went to have my tires rotated the guy said we just set them all at 120 f/p and he was using an impact. You don''t know what the torque is really, if only using an impact wrench IMO. I bought a #100lb torque stick and he WILL use it next time. Ed
