Dan, what rear wheels are you using? -Al

Re: Wheel Studs
 

Centerlines !

Re: Wheel Studs
 

Take a look at the back side of the wheel where it mates up to the axle flange. The back of the wheel must be perfectly flat where it mates to the axle flange. My buddy had a set of centerline wheels and the backs were not flat. They had a concave area near the stud holes and he could not keep the lug nuts from coming loose and breaking the studs. He finally had to change the wheels and junk the centerlines. After that no problems with the studs breaking or the lugs loosening up.

Thanks Mike;
Did that, took a straight edge and they are flat.

FWIW been drag racing for a long time.
Blew up engines and transmissions.
Stuff happens and hope nobody has the surprise of losing a wheel.

All the advice here is good!
When racing any vehicle got to pay attention to everything.

Looking at ARP again for Studs.
When I freshened the Heads used ARP Head and Header Bolts.

Re: Wheel Studs
 

this may sound stupid but are you using the "correct" lug nuts both either in thread pitch not METRIC on an SAE thread or vice versa as well as the style of nut for that wheel--- IE: cone ,shank etc.?? Weld/Centerline says 85 pounds for most of their wheels with 1/2 inch studs so something is not correct in the application here.Also I would get another torque wrench to tighten them then double check the torque with your wrench see if it clicks at the same rate---FED 387

Re: Wheel Studs
 

Do you have the correct lug nuts? If the taper is not right, the lug nut won't seat right.
Do all the lugs loosen up if 85# is used?

Here is a good one: LOL ~!

Re: Wheel Studs
 

They do now !
In fact replaced all the Washers.
Some were deformed.

The new Studs were tightened until they felt snug and seated.
The rears are now at 110# and fronts back at 85#

Re: Wheel Studs
 

Now that's funny. Almost looks like it was probably planned

Re: Wheel Studs
 

I had 4 of the 5 1/2" wheel studs shear on my car in 2007 just after painting it. The problem was the lug nut shank did not engage far enough into the spacer. Even if you are not running spacers, if it is a shouldered lug nut the stud may be allowed to flex and shear. I installed 5/8" screw in wheel studs and never had another problem with wheel studs.

Are you sure the lug nut is not grabbing the wheel and that is the false torque reading? Do the lug nuts drag of hang up when threaded onto the stud with no wheel the full thread length? I also use a dab of anti seize on the wheel studs.
