GREPSPUD 5x4.5" Trailer Hub Kit 2000 lb for 1-1/16" Spindle — Pre-Lubed Hubs & Seals

GREPSPUD 5 on 4.5'' trailer hub kits are a complete, pre-lubricated wheel hub assembly designed for 2,000 lb axles with 1-1/16" straight spindles.

This ready-to-install kit gives you two fully assembled hubs with L44649 bearings and 1.25" grease seals already packed with lubricant, plus every fastener and cap needed for a straightforward trailer wheel replacement. It’s built for durability with black-coated steel hubs, zinc-plated dust caps, and rust-resistant hardware, and it’s packaged to protect parts during shipping.

What exactly comes in the GREPSPUD 5x4.5" hub kit?

The kit includes two hubs and a complete set of bearings, seals, caps, and hardware so you won’t need to source extra parts. Components are pre-assembled where appropriate to speed installation and reduce mess.

• 2x 5x4.5" hubs (O.D. 5.66", I.D. 1.98", height 4.25")
• 4x L44649 bearings (I.D. 1-1/16") pre-installed and greased
• 2x grease seals (I.D. 1.25") pre-assembled
• 10x lug nuts (1/2"-20), 2x spindle nuts (1" thread), 2x washers (I.D. 1"), 2x cotter pins (2.3"), 2x dust caps (O.D. 1.98"), 2x rubber plugs (1.18" hole)

Will these hubs fit my trailer spindle and bearings?

These hubs are made for straight spindles with a 1-1/16" bearing inner diameter and use L44649 outer/inner bearings; they are not compatible with tapered spindles. Always verify spindle and seal sizes before ordering to avoid fitment issues.

• Fits 1-1/16" I.D. L44649 bearings only
• Accepts 1.25" I.D. grease seals
• Castle spindle nuts sized for 1" spindle thread
• Not suitable for tapered spindles

How difficult is installation and what tools will I need?

Installation is simplified because the bearings and seals come pre-assembled and lubricated; you’ll still need basic mechanic tools and a few consumables. Follow standard hub-install procedures and use a rubber mallet or wooden block when seating the dust cap to avoid denting.

• Basic tools: socket set, torque wrench, pliers, hammer or rubber mallet
• Pre-lubed bearings reduce immediate greasing steps
• Seat dust cap carefully with wood block to prevent damage
• Confirm spindle length and thread size before tightening

How durable are the hubs and will they resist corrosion?

GREPSPUD hubs are manufactured from quality steel with protective finishes: black coating on the hub body and zinc plating on dust caps to reduce corrosion. Precision bearings are designed for low friction and quieter operation under normal trailer loads.

• Black-coated hub bodies for surface protection
• Zinc-plated dust caps to limit rusting
• High-precision bearings for reduced friction and noise
• Sturdy packaging to minimize transport damage
