Aeagle 5-on-4.5" Hot-Galvanized Idler Hub Kit — 2-Set for 3,500 lb Trailer, 1-1/16" to 1-3/8" Tapered Axle with Bearings & Seals

If you need a full replacement hub assembly for a 3,500 lb trailer axle that accepts 1-1/16" to 1-3/8" tapered spindles, this Aeagle kit arrives ready to install. Each kit contains two 5-hole 4.5" hot-galvanized idler hubs plus matched inner and outer cone bearings, grease seals, dust covers, and hub nuts — everything required to rebuild two hubs. The hot-galvanized finish helps resist corrosion near saltwater and freshwater alike, and the parts are tested before shipping with a 12-month limited warranty for consumer confidence.

What components are included and why do they matter?

This kit is comprehensive: you get both hubs and the hardware necessary to mount them correctly. Matched bearings and seals reduce the risk of premature wear and help maintain smooth rotation under towing loads.

• 2x 5-hole 4.5" hot-galvanized idler hubs — corrosion-resistant finish
• 2x inner cone bearings (fit L68149, I.D. 1-3/8")
• 2x outer cone bearings (fit L44649, I.D. 1-1/16")
• 2x grease seals and 2x rubber dust covers for long-term protection
• 10x hub nuts for secure fastening and spares

Will these hubs fit my trailer axle and bolt pattern?

The hubs are built for a 5-on-4.5" bolt circle and specifically for tapered axles that transition from 1-1/16" to 1-3/8" diameters. Verify both your bolt pattern and spindle taper before ordering to ensure compatibility.

• 5 on 4.5" bolt circle — standard for many 3,500 lb trailers
• Accepts tapered axles with 1-1/16" to 1-3/8" dimensions
• Designed as idler hubs (no drum brake provisions)

How should I install and torque these hubs for safe operation?

Proper installation preserves bearing life and prevents overheating. Use a torque wrench for initial tightening and follow the specified rotation-backoff sequence to set bearing preload correctly.

• Tighten to 60 N·m (44 lb·ft) initially
• Back off by 110° to achieve correct bearing preload
• Pack bearings with marine-grade grease and fit seals fully to prevent water ingress

What maintenance and durability can I expect from the Aeagle kit?

The hot-galvanized hubs and sealed bearings are intended to offer extended service life, particularly in wet or corrosive environments. Regular greasing and periodic inspection will keep the assembly functioning smoothly.

• Hot-galvanized finish resists rust in coastal or humid conditions
• Grease seals and dust covers keep contaminants out of bearings
• Parts are tested before shipping and covered by a 12-month warranty
