Buying Guide: Key Considerations And Comparisons
- Seal size and compatibility: Measure your current seal’s inner diameter and outer diameter, then match to ID 1.719″ and OD 2.565″ where stated. Confirm the spindle type (e.g., #84 spindles) and whether your setup is EZ-Lube.
- Seal material and design: Double lip seals with a steel core and spring generally provide better resistance to splash water and dirt. NBR rubber is common for weather resistance and flexibility.
- Durability vs. value: Value packs (like GREPSPUD and RV MURTS) offer multiple replacements at once, reducing future trips for replacements. Premium options may prioritize long-term durability in harsh climates.
- Installation considerations: Cotter pins are often included; ensure the pin length matches your axle design. Carefully clean the hub bore and seal groove before installation to avoid leaks.
- Environmental conditions: If you trailer in salty or humid environments, consider seals with corrosion-resistant cores or coatings (steel cores with protective treatments) for extended life.
