1980 c10, Rally wheel lug nut torque...

[hotrod24]

I got a set of rally wheels and i was wanting to torque them to the right spec, I can not find it in one of my manuals no where... Would someone know the torque or know where it is in a manual?

metal rims get torque till i grunt  i usually use a 4way and work it with my arms and weight. if you use an impact they make lug sockets with extensions that will flex the necessary amount due to the lug size. tell you the truth i never had a problem with steel rims just kind of leery with the aluminum ones

[hotrod24]

Yea thats what i was doing, But i was thinking maybe i should torque them to the right lbs...

[hotrod24]

I found it 103 lbs...

you can warp rotors if you get the lugs too tught

[hotrod24]

Really thats what my haynes said it was lol...

I just hit mine till the impact stops turning.

what  never had a rotor warp due to over tighten but lugs/ bolts stretch lose and their strength that’s why they make special tool for impacts when it comes to the tq on them. A cheap good impact your talking over 350 tq and a good impact over 700tq your lucky you haven’t broke anything. And don’t even think about doing that to a aluminum rim.

High school auto shop failure...

[1979C20]

In my high school.auto shop he made us tighten them with a torque wrench. But my dad and my buddies dad who owns a shop taught me to just hit them with the impact. High speed, low torque setting.

[beastie_3]

still a failure, and that shop is looking at a lawsuit

[Irish_Alley]

I have used an impact before but only low speed just to put them on then use a 4-way to snug them on. This is why they you cant use a extension on a tq wrench cause it will flex and your readings will be off that’s why they use sockets with extensions on to do the wheels. Different dia. Of the extension will allow it to flex. And if an impact is less effective if it’s flexing greatly reducing the amount of tq. My father in-law when he gets his tires rotated as soon as he gets home he takes the tires back off just to put them back on with a 4-way

Just snug them all the same to seat the lug nuts in the wheel with the impact if you use one then use a torque wrench. It only takes a few minutes. I can break lugs off with my impact wrench. Other than having uneven torque on you lugs you can also make them so tight that on the side of the road with small tire changing tools you or your wife/girlfriend/customer/whoever cant get them off.

What i am doing is snugging them on, Then taking my torque wrench and torquing them to 103 lbs...

i have a 1/2 drive impact from napa that was like $99 and if you let it rattle it will do more than 500ft/lbs, which is too much for even the semi wheels i was torquing. i always torque car wheels to 100ft/lbs.
