If its a sharp turn , its likely that its caused by the tag axle
. Ytd took SBS9812R on 88 and when teh bus made a sharp turn ,
funny noises are made as well . Thats becuz , since teh steering
function of the tag axle is turned off (which serves to help steer
the bus better) , the tires are placed under more stress. Sry for
teh poor explanation.
