4Set L68149 L44649 Trailer Hub Bearings Kits for 3500LB #84 Spindle

In this review the 4Set L68149 L44649 trailer hub bearings kit is evaluated for owners of small to medium boat trailers with a 3500 lb capacity and #84 spindle. The bottom line: this kit is for DIY trailer owners who want a comprehensive, ready-to-install bearing package that replaces inner and outer bearings, races and seals for 1-1/16' to 1-3/8' spindles. The single biggest reason to buy is the complete 40-piece value pack that supplies all wearable hub components in one shipment, reducing downtime when servicing trailer hubs.

Key Features

• Complete 4-set package: Includes four of each bearing, race and accessory so an entire trailer axle can be serviced at once without multiple orders.
• Correct fit for #84 spindle: Engineered to fit 3500 lb trailers with 1-1/16' to 1-3/8' spindles, including EZ-Lube axles, which simplifies compatibility checks.
• Pre-lubricated bearings: Bearings arrive with factory lubrication to protect components in storage and reduce initial wear at first installation.
• Double-lip grease seals: NBR rubber seals with dual lips provide extra protection against water and road contaminants for marine trailer use.
• Durable materials: High-quality steel races and bearings deliver stable operation and reduced noise under load when installed correctly.
• Value accessories included: Dust caps, rubber plugs, spindle nuts, washers and cotter pins are all supplied so no extra parts are required for a standard hub rebuild.

Who It's For

This kit suits boat owners, weekend DIY mechanics and small fleet operators who maintain 3500 lb trailers with #84 spindles and want a single purchase that includes bearings, races, seals and hardware. It is particularly useful for those with EZ-Lube axles who need matching components for greased hubs.

Those who should look elsewhere include owners of trailers with different spindle sizes or commercial heavy-duty trailers above the 3500 lb rating. Also, buyers who expect pre-fit pressed cups may need to plan for light mallet work, since the hub cup is designed slightly larger to ensure a tight final fit.

Pros & Cons

Pros

• Comprehensive 40-piece kit provides everything needed to service four hubs in one purchase.
• Good build quality with steel bearings and NBR double-lip seals for marine resistance.
• Pre-lubricated units reduce initial break-in wear and simplify first-time installs.

Cons

• Hub cups are made slightly larger for a tight fit, so installation may require a wooden block or rubber mallet and a bit of care.
