Esteem GLX Wagon Plus L4-1.8L (1999)
Wheel unbalance causes most of the highway speed vibration problems. If a vibration remains after dynamic balancing, its possible causes are as
follows:
1. Tire runout.
2. Wheel runout.
3. Tire stiffness variation.
Measuring tire and/or wheel free runout will uncover only part of the problem. All three causes, known as loaded lateral runout, must be checked by
using a Tire Problem Detector (TPD). If TPD is not available, alternative method of substituting known good tire and wheel assemblies on the
problem vehicle can be used, although it takes a longer time.
