Squeal noise occurs due to lateral stick-slip mechanism while negotiating curve track. It is necessary to estimate lateral creep force that represent unstable response for prediction of squeal noise. There are many theories to estimate contact force for 3D rolling contact problem. But most of them are limited by various assumptions. This paper aims to predict occurrence of squeal noise without limitation that concerning 3D rolling contact theories using finite element analysis. The relationship between adhesion coefficient and creepage was presented by calculating lateral creep force in the contact area. Occurrence of squeal noise was assessed by friction characteristic curve. Squeal noise was expected when creepage is over 0.005.
