iBroPrat Trailer Hub Bearing Kit, 2 Sets 3500 lb #84 Spindle (L68149/L44649) — Complete Bearings, Seals & Hardware

If you tow a boat or small trailer, worn wheel bearings and seals are common maintenance items that affect safety and noise. This iBroPrat kit bundles two full bearing assemblies designed for 1-1/16" to 1-3/8" trailer axles with #84 spindles (3500 lb rating), so you can repair both hubs at once or keep a spare set. The kit focuses on durability and convenience: precision bearings and races, double-lip grease seals to limit leakage, and extra dust caps, spindle nuts, and rubber plugs so you won't be left missing parts during roadside repairs.

How will this kit fit my trailer's axle and spindle?

The kit is sized for standard 3500 lb trailer setups using #84 spindles and fits axles from 1-1/16" to 1-3/8". iBroPrat provides the specific bearing and race part numbers (L68149, L68111, L44649, L44610) so you can verify compatibility against your existing components or the trailer manual. Because two sets are included, you'll have parts for both sides or a spare set for future use.

• Fits #84 spindle assemblies rated 3500 lb
• Compatible with 1-1/16" to 1-3/8" trailer axles
• Includes L68149/L68111 and L44649/L44610 bearing/race pairs
• Two complete sets—repair both hubs or keep a reserve

What specific parts are included and why they matter?

Each kit contains a comprehensive set of hardware needed for a proper hub service: inner and outer bearings with matching races, grease seals designed to resist leakage, and external components like dust caps, spindle nuts, washers, and cotter pins. iBroPrat emphasizes completeness so you avoid trips to multiple stores for missing parts; the included extras also reduce downtime during on-trailer repairs.

• 2× L68149 bearings and 2× L68111 races per set
• 2× L44649 bearings and 2× L44610 races per set
• Grease seals (171255TB, 1.719" I.D.), dust caps (1.98"), rubber plugs
• Spindle nuts, washers, cotter pins and additional shims for fitment

How durable and reliable are these components?

iBroPrat selects precision-manufactured bearings and heat-treated races to reduce noise and improve service life. The grease seals use a double-lip design to help retain lubricant and resist contaminant ingress, and the kit is packed carefully to avoid damage in transit. The total weight and robust materials indicate a substantial, long-lived assembly compared with economy kits that omit critical parts.

• Precision bearings for lower operating noise
• Double-lip grease seals minimize leaks and contamination
• Heavy-duty packaging prevents shipping damage
• Extra hardware provided for emergency or spare use

What tools or steps do I need to install these parts?

Basic hub overhaul tools are required: jack and stands, bearing puller or hammer and drift for races, bearing packer or grease gun, torque wrench for spindle nuts, and common hand tools. Follow safe lifting procedures and torque manufacturer's specs; if you're unfamiliar with hub service, a trailer shop can fit the kit quickly. The included hardware reduces the need to source additional pieces mid-job.

• Jack, stands, and wheel chocks for safe lifting
• Race installer or drift, bearing packer or grease gun
• Torque wrench and basic socket set for spindle nuts
• Replace seals and inspect bearings/races for wear before reassembly
