How often should I service my wheel bearings?
25,000 to 30,000 miles
Most serviceable wheel bearings need maintenance every 25,000 to 30,000 miles, or during every brake service. But, the average life of a sealed wheel bearing and hub assembly is about 85,000 to 100,000 miles, without the opportunity for a technician to repack the bearings.
How often should you service caravan wheel bearings?
Wheel bearings get a workout on any caravan and should be checked and re-greased every 10’000km or 12 months. Don’t forget you’ll need a new split-pin and a bearing seal for each axle, and be prepared to replace the inner and outer bearings if they are pitted or worn.
When should wheel bearings be inspected and when should they be replaced?
Sealed bearings should be brought in for inspection every 30,000 miles or sooner if you hear any unusual noises. The typical wheel bearing noise is a rotational humming noise while you’re driving that typically varies with speed or when turning. Sealed bearings can typically last as long as 100,000 miles or more.
How much does it cost to replace wheel bearings on a caravan?
If all you can have done due to time or cost constraints is a bearing and brakes check/lube/adjustment, it’ll cost you about $200 for a single axle and about $300 for a tandem.
When do you need to inspect your wheel bearings?
Find and fix problem wheel bearings during regular maintenance. Wheel bearings must be properly adjusted and run in clean lube, or you can expect increased costs from failure. Bearings should also be inspected for wear at regular intervals and whenever you or your driver finds some telltale signs.
What should I know about care and maintenance of bearings?
Care and Maintenance of Bearings (Revised) We thank you for your interest in NTN bearings. This booklet is intended as a guide to bearing maintenance, with the main consideration being on-site bearing maintenance. Bearings may fail earlier than the expected rolling fatigue life.
Why do bearings break so often in the field?
The problems are avoidable by correct selection, proper handling and maintenance, and are distinguished from the fatigue life of the bearing. However, breakdowns due to improper application, bearing design, and maintenance are more frequent than flaking due to rolling fatigue in the field. 2. Inspection of Bearings
What causes a wheel bearing to become unserviceable?
Every bearing becomes unserviceable in the course of time even if it is installed correctly and operated properly. The raceway surfaces and the rolling contact surfaces of the rolling elements are repeatedly subjected to compressive loads, and the surfaces eventually flake.
