SERVICE INFORMATION
Isuzu has recently made changes to the automatic locking hub assemblies. The hub drive clutch assembly engagement spring now receives special heat
treatment. The new drive clutch comes packed with wide temperature range grease. The combination allows for superior performance in extremes of hot
or cold temperature.
NOTE:
Additional grease may be purchased if required for installation or repair of auto locking hubs. Only the grease specified below is authorized
for use with the modified drive clutch assembly. DO NOT USE THE NEW WIDE TEMPERATURE GREASE IN OLD STYLE HUBS.
