Aeagle 2-Pack 5-Lug Trailer Idler Hub Kits 5-on-4.5in Bolt Circle — 3,500 lb Axles, Matched Bearings & Seals

Aeagle’s two-pack 5-lug idler hub kit replaces L68149/L44649 bearings to fit 1-1/16" to 1-3/8" tapered spindles on 3,500 lb trailer axles with a 5-on-4.5" bolt pattern.

This pair of idler hubs is designed as a direct-fit replacement for common 3,500 lb trailer axle applications that use a 5-on-4.5" bolt circle. Each kit includes inner and outer cone bearings sized to match L68149 (inner, I.D. 1-3/8") and L44649 (outer, I.D. 1-1/16"), plus grease seals, rubber dust caps, and hub nuts so you have what you need to reinstall both wheels. The hubs are built to withstand towing loads and routine road conditions while letting you service or upgrade your trailer’s rolling assemblies quickly.

What components are included in each two-hub kit and their specifications?

Each package supplies everything required to replace both idler hubs on a tandem setup. Parts are organized to match the spindle sizes and industry bearing references for easy cross-checking.

• 2 x 5-hole idler hubs for 5-on-4.5" bolt pattern
• 2 x inner cone bearings compatible with L68149 (I.D. 1-3/8")
• 2 x outer cone bearings compatible with L44649 (I.D. 1-1/16")
• 2 x grease seals, 2 x rubber dust caps, and 10 hub nuts (for both hubs)

How do these hubs perform under normal towing conditions?

The hubs are engineered for standard utility and boat trailers rated at 3,500 lbs per axle. They are machined and assembled to provide stable rotation, even wear on bearings, and consistent sealing to keep lubricants in and contaminants out.

• Compatible with common 3,500 lb trailer axles using tapered spindles
• Seals and dust caps protect bearings from water and road debris
• Pre-tested before shipping for functional rotation and fit

What are the installation and torque recommendations?

Installation follows standard tapered-spindle procedures. Use a calibrated torque wrench to achieve the initial preload, then follow the specified rotation-backoff and cotter-pin/dust-cap steps for safe operation.

• Tighten hub nut to 60 N·m with a torque wrench initially
• Back off the nut by approximately 110° before securing
• Confirm free rotation and proper endplay, then fit dust cap and torque hardware as required

What warranty and quality checks come with the kit?

Aeagle backs these hub kits with a 12-month limited warranty and conducts basic functional checks prior to shipment. That inspection helps ensure hubs rotate freely and bearings seat correctly, reducing the risk of immediate fitment issues on arrival.

• 12-month warranty included
• Each unit tested before shipping for rotation and basic fit
• Replacement bearings matched to L68149 / L44649 specifications

Who is this for: This two-hub set is intended for trailer owners, fleet operators, and DIY mechanics who need a dependable replacement for worn or damaged idler hubs on 3,500 lb axles that use a 5-on-4.5" bolt pattern and 1-1/16" to 1-3/8" tapered spindles. It’s a practical, cost-effective option when you want matched hubs, bearings, and seals to restore safe rolling performance without sourcing multiple separate parts.
