| Location | Description | Type | Basic value | Tolerance 1 | Tolerance 2 |
|---|---|---|---|---|---|
| Wheel to wheel hub on front and rear axle when using silver wheel bolts (up to model year 2011), M14 x 1.5 | Apply a light coating of Optimoly TA (aluminum paste) to the thread, shank and under the head (between screw head bearing surface and spherical cap ring) of the wheel bolts. Do not grease bearing surface of the spherical cap facing the wheel. If heavily soiled, clean bolts first with a lint-free cloth. Replace damaged wheel bolts (cannot be reworked) | Tightening torque for using silver wheel bolts (up to model year 2011): 130 Nm/96 ftlb. (160 Nm/118 ftlb. also permitted retroactively) | 130Nm Nm (96 ftlb.) (160 Nm/118 ftlb. also permitted) | ||

| Wheel to wheel hub on front and rear axle when using black wheel bolts, M14 x 1.5 | Apply a light coating of Optimoly TA (aluminum paste) to the thread, shank and under the head (between screw head bearing surface and spherical cap ring) of the wheel bolts. Do not grease bearing surface of the spherical cap facing the wheel. If heavily soiled, clean bolts first with a lint-free cloth.

| Wheel to wheel hub/central bolt | All contact surfaces of the wheel, wheel hub and brake disc as well as the trapezoidal thread in the wheel hub must be free of abrasion, sand, dust or chips. Apply some aluminum paste (Optimoly TA) on the trapezoidal thread on the wheel hub if necessary. Grease the conical surface of the central bolt with a very light coating of aluminum paste before fitting each wheel. For advanced grease specifications (which are only necessary under certain conditions), refer to the description 440519 REMOVING AND INSTALLING WHEEL WITH CENTRAL BOLT . | 3-step tightening procedure (Step 1: Tighten to 600 Nm (444 ftlb.). Step 2: Loosen the central bolt again (slightly) by approx. 60 angular degrees (1/6 turn). Step 3: Tighten to 600 Nm (444 ftlb.)). The tightening torque was increased to 600 Nm (444 ftlb.) (previously 500 Nm (370 ftlb.)) in the course of model year 2011. The higher tightening torque also applies to older vehicles. | 600 Nm (444 ftlb.) |
