E350 and F350 vehicles with dual rear wheels are equipped with wheels (front/rear) which are center piloted to the hub and are attached with integral two-piece, swiveling lug nuts. The lug nut torque specification is 140 ft.lbs. +/- 15 ft.lbs. (right hand threads are used at all four wheel locations). See Figure 5 of the attached sketches for description of the wheel attachments.
Figure 4 - REAR WHEEL LUG NUT USAGE:
WARNING: Use only integral two-piece swiveling lug nuts on 1985 vehicles equipped with dual rear wheels. Do not attempt to use cone shaped onepiece lug nuts on these vehicles. If used on wrong wheels, cone shaped one-piece lug nuts can come loose in vehicle operation. Do not attempt to use wheels which have cone shaped lug nut seats on these vehicles. Intermixing of different types of wheels can lead to damage to the wheel mounting system. Use of cone shaped one-piece nuts or intermixing of wheels could allow wheels to come off while vehicle is in motion, possibly causing loss of control and a collision. See Figure 4 of the attached sketch for lug nut description."
