Dealing with a rear axle leak<\/strong> can be frustrating, especially when you’re unsure which seal to choose. Pick the wrong one, and you’ll face another leak in months.<\/p>\n

To fix a rear axle leak properly, you must select a seal that matches your axle type, shaft diameter, and operating conditions. Material and lip design also matter for longevity and performance.<\/p>\n

The right axle seal saves you from recurring leaks, costly downtime, and frustrated customers or drivers. Let\u2019s explore how to make the right choice with confidence.<\/p>\n

What are the symptoms of a rear axle seal leak?<\/h2>\n

You might first notice oil on your garage floor, or maybe hear a humming noise from the rear.<\/p>\n

Rear axle seal leaks typically show signs like fluid around the wheel hub, burning smells, differential noise, or rear brake contamination\u2014especially in drum brake systems.<\/p>\n

Why is choosing the right axle seal important?<\/h2>\n

Not all axle seals are equal. Wrong fitment, wrong material, or poor lip design = leak again soon.<\/p>\n

Axle seals protect your differential oil from escaping and block dust or water from entering. The right seal reduces friction, heat, and long-term failure.<\/p>\n

We always advise checking the OEM number or using our oil seal cross-reference chart<\/a> to avoid mismatch.<\/p>\n

What materials are best for rear axle seals?<\/h2>\n

Material choice is vital, especially for commercial or off-road vehicles. NBR works fine for daily use, while FKM is ideal for heat, pressure, and longevity.<\/p>\n

Silicone is more flexible but less abrasion-resistant, and PTFE offers chemical resistance for specialized environments.<\/p>\n

How to select the right seal size and design for your axle?<\/h2>\n

Always measure shaft and bore diameters with calipers. Consider lip type: single lip for basic sealing, double lip for dust\/oil protection, and triple lip for rugged terrains.<\/p>\n

We recommend using OEM reference numbers or working with a supplier like Hengoseal for matching.<\/p>\n
