Title:
WHEEL BALANCE ADJUSTMENT PROCEDURE
Models:
'98- '00 GS 300/400
Introduction
GS 300/400 alloy wheels have a decorative outer wheel flange which does not accept standard Lexus clip-on type wheel weights. To properly adjust wheel balance, stick-on type wheel weights must be used. Some wheel balancers do not have a "hidden weight" function which is used to measure the tire/wheel assembly imbalance in the location of the stick-on type wheel weights. The procedure included in this bulletin can be used to balance GS 300/400 tire/wheel assemblies on wheel balancers that do not have a "hidden weight" function.
Applicable Vehicles
