Lug Nut Torgue

[wayne]

After seeing a bunch of post lately about wheel studs breaking and nuts comming loose and wheels flying off I was wondering if people actually know what the torque specs are. Looking for specs on all axles, 10 bolt up to 14ff's.

most lugnut torque is around 55-70 pounds

4WPW told me 120 lb/ft on my 9/16" studs on the 14B/D60 with AE 589 wheels................

Here's a set of specs straight out of my 1972 Owner's manual

Series K10.....................7/16" Bolts (6)......55-75 Lb/Ft
Series C.........................1/2" Bolts (5).......65-90 Lb/Ft
Series C, P20, 30............9/16" Bolts (8)......90-120 Lb/Ft
Series C30 (HD Wheels).....5/8" Bolts (10)...200-250 Lb/Ft

That should get your list started.....! /forums/images/icons/smile.gif
