shliyitx Trailer Bearing Kit 2-Set for 3500 lb D-Style Axles — 1.719" Grease Seal, Chrome-Steel Bearings

shliyitx 2 Sets L68149 L44649 Trailer Axle Bearing Kit provides two complete hub-bearing assemblies (14-piece total) designed for 3500 lb D-style tapered axles with a 1.719" grease seal.

This kit supplies every wearable and fastening part you need to service or replace bearings on compatible boat, utility, or RV trailers. Built from chrome steel bearings and double-lip grease seals, the set includes inner and outer bearings and races, tang washers, cotter pins, grease seals, dust caps, spindle nuts and shims — enough parts for two hubs and some spares so roadside repairs or scheduled maintenance go smoothly.

Which axles and spindles will this bearing kit fit?

These kits are intended for D-style tapered spindles used on 3500 lb trailer axles that accept 1-3/8" to 1-1/16" axle shafts and use Spindle #84 dimensions. The grease seal inner diameter is 1.719" (ID) to match the spindle journal.

• Compatible with D-style tapered spindles and EZ-lube axles.
• Designed for 3500 lb (single axle rating) trailer applications.
• Fits Spindle #84 (check spindle journal diameter before install).
• Suitable for boat trailers, utility trailers and many RV trailer hubs.

What parts are included and why they matter?

Each purchase includes two complete sets (14 pieces total) to rebuild two hub assemblies or keep spares on hand. That means inner/outer bearings and races, grease seals sized 1.719" ID, tang washers, and cotter pins — all items used during a routine hub rebuild.

• 2 × L68149 inner bearings and 2 × L68111 inner races for the inner cone.
• 2 × L44649 outer bearings and 2 × L44610 outer races for the outer cone.
• 2 × 171255TB grease seals (1.719" ID, 2.565" OD) to keep lubricant in and contaminants out.
• 2 × tang washers, 2 × cotter pins, dust caps, spindle nuts and shims included for assembly and safety.

How durable and reliable are the components under load?

Bearings are manufactured from chrome steel for wear resistance and lower operating noise; the seals are double-lip to reduce grease leakage and block dirt. These materials and construction are appropriate for highway speeds and the weight class specified, provided installation and maintenance follow recommended torque and lubrication practices.

• Chrome-steel bearings for strength and longer life in trailer use.
• Double-lip grease seals help prevent lubricant loss and contamination.
• Includes spare washers and shims to fine-tune bearing preload and fit.
• Parts meet typical heavy-load trailer service expectations when installed correctly.

How easy is installation and what tools or checks are required?

The kit contains the hardware commonly needed to replace bearings, so you generally won’t need an extra trip to the parts store. Basic shop tools — bearing packer (or grease and gloved hands), socket set, torque wrench, hammer and punch for the cotter pin — and knowledge of correct bearing preload are required.

• Includes tang washers and cotter pins for secure spindle retention or optional cotter-pin locking.
• Shims and washers provided to set proper endplay and bearing preload.
• Pack bearings with quality wheel grease and torque according to manufacturer specs.
• Confirm spindle journal diameter and spindle type (D-style) before starting.

Who is this kit for? Installers, weekend DIYers, and fleet owners who service 3500 lb-rated trailers will find this shliyitx kit useful. It's aimed at anyone rebuilding two hubs or stocking spares for boat, utility, or RV trailers with D-style tapered spindles that match the listed dimensions. If you’re unsure about fitment, compare your spindle number and journal diameter to the specs before ordering.
