Mounting wheel on vehicle

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.

The wheel bolt consists of two parts that are permanently joined together. Other wheel bolts must not be used.

Use suitable commercially available tools (wrench size 19 mm). Never use an impact bolter to tighten the wheel bolts.

Always apply a thin coat of Optimoly TA (aluminium paste) on the thread of the wheel bolts, on the shank and between the bolt head bearing surface and spherical cap ring (under the head).

CAUTION: Do not grease the spherical cap bearing surface of the wheel bolts that faces the wheel!

In the case of heavy soiling, first clean the wheel bolts and the concavities in the wheel with a lint-free cloth.

Damaged wheel bolts must always be replaced. This damage includes mechanical damage to the thread, the spherical cap and damage resulting from seizure of the bolt head bearing surface and spherical cap ring.

CAUTION: Rework on wheel bolts is impermissible.

Screw in wheel bolts by hand and then tighten evenly. Start at the top when tightening. Always observe the specified tightening torque of 130 Nm (96 ftlb.).
