Adding Grease Does Not Tell You What Is Inside the Hub
A grease fitting is convenient, but it cannot show you whether a bearing is damaged, a race is worn, or a seal has failed. At NTR Trailers, we want trailer owners to understand the difference between adding lubricant and completing a proper bearing inspection and service.
Contact us about bearing service at our Harborcreek shop near Erie, PA.
What E-Z Lube Does—and What It Does Not Do
Dexter’s E-Z Lube system is designed to route grease through the hub to the inner and outer bearings. Used correctly, it can purge old grease. It is a useful lubrication feature, but Dexter says it does not replace periodic bearing inspection.
Dexter’s guidance for its serviceable E-Z Lube hubs calls for removal and bearing inspection every 12 months or 12,000 miles. Follow the instructions for your actual axle and hub; maintenance requirements can differ, and sealed bearing designs are not serviced by repacking.
Why Removing the Hub Matters
With a serviceable hub removed, the bearings, races, seals, and nearby brake components can be examined. Adding grease through the spindle fitting cannot substitute for that view. If wear or contamination is present, the affected parts need attention rather than simply more grease.
Correct grease, seal condition, and lubrication technique matter. Dexter warns that injecting grease too quickly can force it past the seal and into the brake area. An E-Z Lube fitting should not become an excuse to skip the manufacturer’s inspection schedule.
Schedule Bearing Maintenance Before a Breakdown
If the service history is unknown or your trailer is due for inspection, contact NTR before the next haul. Tell us the trailer type, axle or hub information if known, and when it was last serviced.
