Is there any difference in wheel nut torque specs between steel and alloy wheels?
[Response:] There is no difference in the torque requirements for steel or alloy wheels in Volvos. The difference is the studs. The 240s and earlier should be torqued to 85 ft-lbs. The 700/900 should be torqued to 66 ft-lbs, the 850 should be torqued to 81 ft-lbs. [Editor’s note: I use anti-seize on each stud to ease nut removal when changing to or from snow tires.] Torque Values and Procedure: [Tip from Counterman Magazine] Wheel lug bolts should be tightened by torquing to one-half specified value in a star or criss-cross pattern. The final torquing should be done in the same sequence to the specified value. The bolt threads should be clean and free of rust. While it helps to lubricate the threads with light penetrating oil, never use a lubricant that leaves a heavy oil film or that contains a friction modifier. Friction modifiers reduce the friction between the lug nut and bolt and cause false torque readings.
