Finish Balancer

WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

For the balancing, the wheels of the tractive axle are set upon the turntable sensors, for example, front wheels for Front Wheel Drive (FWD) and all 4 wheels for All Wheel Drive (AWD).

NOTE:

Working with a finish balancer requires instruction from the manufacturer of the balancer.

If it is determined when balancing on the vehicle the remaining imbalance is more than 20 grams, the wheel should be rotated on the wheel hub.

NOTE:

Be careful not to scratch off the glued- on wheel trim on these rims.

The surface of the wheel trim is very sensitive.

The rim will have be replaced if the wheel trim is damaged.

The wheel trim cannot be replaced.

-- Mark the point at which the imbalance is indicated.

CAUTION:

The balance weights must be glued on so that rub against the brake caliper or the suspension.

-- Afterwards, unbolt the wheel and rotate its position on the wheel hub so that the marking points downward.

NOTE:

Important! The wheel hub must not turn during this procedure.

-- First, tighten the lowest wheel bolt by hand to approximately 30 Nm.

-- Now tighten the remaining wheel bolts diagonally also to about 30 Nm. This process centers the wheel properly on the wheel hub.

-- - Check again whether the imbalance is less than 20 grams using the finish balancer.

NOTE:

The imbalance should not be smaller than 20 grams under any circumstances before changing balance weight.

-- Remove the wheel bolts again if necessary.

-- Rotate the wheel relative to the wheel hub once more by one or two wheel bolt holes.

-- Tighten the wheels using the method described above.

NOTE:

The imbalance should only be reduced by changing balance weight if the imbalance is less than 20 grams.

-- Balance the wheels until the imbalance is below 5 grams.

-- Tighten the wheel bolts to the specified tightening specification if you have not already done so.

-- Always tighten the wheel bolts to the specified tightening specification using a torque wrench.
