Wheel, Mounting
If brake pads are ceramics, wheel must not fall on the brake rotor, otherwise it will be irreparably damaged. To remove/mount a wheel, install the long assembly pin instead of wheel bolts at the top position (12 o'clock position) and insert the short assembly pin in the wheel bolt mounts for support. In this way, the wheel can glide on the assembly aids when removing/installing.
Only raise vehicle at designated mounting points.
On vehicles with alloy wheels, do not pry out cover caps with a screwdriver but rather use only the special tool designed for this (puller hook in vehicle tool kit).
To loosen wheel bolts, use sockets in the correct size. Sockets that did not fit must not be used any more.
Do not use an impact wrench to loosen anti-theft wheel bolts (lockable wheel bolts).
Do not make wheel bolts dirty.
The secure seating of the wheel bolts and the wheels is only ensured if the instructions and checks below are followed.
The following checks and instructions must be performed with wheel (rim) removed!
The wheel bolts are different lengths and have ball bearing surfaces depending on the model.
Make sure the correct wheel bolts are installed. Refer to Parts Information.
The wheel bolts and wheels will only be secured correctly if the correct wheel bolts are used.
-- Clean any corrosion or dirt from the contact surfaces -arrows- on the brake rotor/wheel hub or brake rotor/brake drum and the wheel (rim).

-- Always wear protective eyewear when cleaning with the Wheel Hub Cleaner: VAS294 009 .
-- Remove rust and dirt on all contact surfaces of the wheel hub and rim using the Wheel Hub Cleaner: VAS294 009 .
-- Coat the wheel centering seat with protective material. Refer to WHEEL CENTERING SEAT, PROTECTING AGAINST CORROSION .
- When mounting a wheel, tighten all wheel bolts evenly by hand.
- Tighten the wheel bolts diagonally to approximately 30 Nm.
- Do not use an impact wrench. Wheel bolts installed with an impact wrench can become loose.
- Lower the vehicles onto the floor. Using the torque wrench, tighten all wheel bolts to the tightening specification in a diagonal sequence. Refer to WHEEL BOLT TIGHTENING SPECIFICATIONS .
-- If necessary, remove oil, grease, grease and corrosion.
