Wheel change/wheel fitting instructions
Special tools and equipment





^ T40004 Master set for wheel bolts





^ 3208 Suction grip
^ V.A.G 1332 Torque wrench

Note:
^ Raise vehicle at jacking points provided.
^ Always use special tool provided (puller from vehicle tool kit or suction grip 3208) Do not use screwdriver to pry off trim caps on vehicles with light alloy wheels.
^ Use socket attachments of correct size to loosen wheel bolts. Worn socket attachments are not to be re-used.
^ Do not use impact wrench for loosening anti-theft wheel bolts (lockable wheel bolts).
^ Keep wheel bolts clean.

WARNING: Secure fastening of the wheel bolts and wheels Is only ensured If the following tests/directions are followed.

The following tests/directions must be performed with the wheel (rim) removed!
^ Check whether the contact surfaces at brake disc/ brake drum and wheel (rim) are free of corrosion and dirt If necessary, remove oil, grease and corrosion and restore the corrosion protection using wax spray D 322 000 A2.
^ Check whether the centering hole of the wheel (rim) and centering of the wheel hub is free of corrosion and dirt If necessary, remove oil, grease and corrosion and restore the corrosion protection using wax spray D 322 000 A2.

Note: Do not allow wax spray to come into contact with brake system components.

^ If rust fell between the brake disc and wheel hub during removal, it must be removed and the contact surfaces must be cleaned.

WARNING: Wear safety glasses when working with compressed air.

^ Collars of wheels (rims) and wheel bolts must be free of oil, grease, corrosion and dirt.
^ Remove any dirt from collars of wheels (rims) with a clean lint-free cloth
^ Inspect wheel bolts and wheel hub threads are clean
^ Clean dirty wheel bolts e.g. using a wire brush. Corroded or damaged wheel bolts must be replaced.
^ If slightly corroded wheel bolts are re-used, they are to be cleaned in the area of the collar and thread and the contact surfaces greased as follows with Optimol TA paste, part no. G 052 109 A2:





A - One-piece wheel bolt
^ Apply thin coat of grease to thread area -2- and collar -1-.
B - Two-piece wheel bolt
^ Apply thin coat of grease to thread area -3- as well as between bolt head resting surface -6- and collar ring -5-.
^ Do not apply grease to surface -4- of collar which rests on rim.

Note: Exclusive use is to be made of Optimol TA paste, part no. G 052 10.9 A2. Paste must not be allowed to come into contact with brake system components.

^ Check whether the wheel bolts can freely be threaded in by hand. The thread of the wheel bolts must not contact the hole in the brake disc.
^ Make sure the hole of the brake disc lines up with the thread of the hub. Wheel bolt thread must not make contact with brake disc hole.

Installing wheels
^ Position wheel on wheel hub and secure by hand with two opposing wheel bolts.
^ Screw in remaining wheel bolts by hand. They must screw in easily. Pay attention to exact centering.
^ Relieve load on wheel if necessary by slightly lifting and tightening two wheel bolts slightly by hand.
^ Screw in evenly all wheel bolts by hand.
^ Tighten wheel bolts crosswise to 50 Nm e.g. using a four-way socket wrench.
^ Lower vehicle onto ground and tighten all wheel bolts crosswise to the specified tightening torque.
Tightening torque 120 Nm
