Maintenance and service 11-31 Wheel nuts tightening torque for aluminum wheel: 74 to 89 lbf·ft (100 to 120 N·m, 10 to 12 kgf·m) This torque is equivalent to applying approximately 88 to 110 lbs (40 to 50 kg) at the top of the wheel nut wrench. Never apply oil to the threaded parts, wheel nuts, or tapered surface of the wheel. Never let the wheel rub against sharp protrusions or curbs. Be sure to fit tire chains on uniformly and completely around the tire, otherwise the chains may scratch the wheel. When wheel nuts, balance weights, or the center cap is replaced, be sure to replace them with genuine SUBARU parts designed for aluminum wheels. Chrome plated wheels (if equipped) There are 2 types of wheel nut wrenches that apply to different lengths. For an aluminum wheel vehicle, the 11.2-inch (285 mm) wheel nut wrench is equipped as a maintenance tool. And for a chrome plated wheel vehicle, the 13.2-inch (335 mm) wheel nut wrench is equipped as well. Always use a wheel nut wrench for a chrome plated wheel. If you use a wrench for an aluminum wheel, you cannot tighten it to the specified torque. When any of the wheels are removed and replaced for tire rotation or to change a flat tire, always check the tightness of the wheel nuts after driving approximately 600 miles (1,000 km). If any nut is loose, tighten it to the following specified torque. A tightening sequence specification for the wheel nuts can be found in the "Flat tires" in chapter 9. 1 900292 1) The length of the wheel nut wrench - CONTINUED -
