HeavyGunner Posted January 25, 2018 Share Posted January 25, 2018 If you're not overloading the axle or abusing the truck in any other way I'd guess it's a defect.

Hobert62 Posted January 25, 2018 Share Posted January 25, 2018 Is the hub worn letting the wheel ride on the studs and not the hub? 2 Quote Link to comment Share on other sites More sharing options...
davehummell Posted January 25, 2018 Share Posted January 25, 2018 I had a driver that thought wheel torque on studs was hammer on the 1" air wrench until it broke the stud or stripped the nut. To much torque? 1 Quote Link to comment Share on other sites More sharing options...
BGarofalo Posted January 25, 2018 Share Posted January 25, 2018 Worn hub as Hobert62 said. The pilot in the center of the hub is worn causing studs to fatigue and fail. Quote Link to comment Share on other sites More sharing options...
Timmyb Posted January 26, 2018 Share Posted January 26, 2018 (edited) Is it 10 stud or spider hubs? My understanding is the hub only locate the rim while installing, and the nuts clamp the rim in place and it shouldn't really be running in the locating arms. Of course I may be mistaken in my knowledge I had a mate with worn cleats that kept breaking studs. If you have 10 stud then this obviously won't concern you.

kscarbel2 Posted January 26, 2018 Share Posted January 26, 2018 If you're not abusing the truck, I suggest you have your Mack brand dealer's service manager coordinate having you bring the truck down when his Mack district service representative is next in town for their regular visit.

41chevy Posted January 26, 2018 Share Posted January 26, 2018 Wonder if the install of the studs damaged them. Seen it happen with "short cuts" Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment Share on other sites More sharing options...
Timmyb Posted January 26, 2018 Share Posted January 26, 2018 Maybe mark the stud and see if it’s the same one/s. Is it possible the stud is not straight? Quote Link to comment Share on other sites More sharing options...

41chevy Posted January 27, 2018 Share Posted January 27, 2018 Possibly the hub flange surface is not true to the wheel. When the lugs are tightened it pulls the hub flange to the wheel and stresses the stud. You or the dealer can check it for run out on the face with a dial indicator easy enough.

Hobert62 Posted January 27, 2018 Share Posted January 27, 2018 Driver issue? Is somebody hitting the lug nuts / studs on a high curb and breaking them off? Quote Link to comment Share on other sites More sharing options...
