The best 3500 lb axle bearing kit depends on the axle fit and how many hubs you plan to service. For multiple repairs, the iBroPrat and GREPSPUD kits each include four sets and hardware such as dust caps and spindle nuts. WESTERNPRIME offers four bearing-and-seal sets without the same range of extra parts. For a two-hub job, Misakomo and XiKe provide smaller kits. Confirm your spindle, bearing numbers, and seal dimensions before ordering.
| Kit | Set quantity | Best suited for |
|---|---|---|
| iBroPrat | 4 sets | Multiple repairs and extra hardware |
| GREPSPUD | 4 sets | Bulk replacement with listed fit details |
| WESTERNPRIME | 4 sets | Bearings, races, and seals only |
| Misakomo | 2 sets | A two-hub job with included hardware |
| XiKe | 2 sets | A smaller kit with stated inspection features |
iBroPrat Four-Set Bearing Kit
Best for: Owners preparing for several hub repairs or wanting spare service hardware. This package includes four sets of L68149 and L44649 bearings, matching L68111 and L44610 races, and four grease seals with a listed 1.719-inch inside diameter.
Each set also includes a cotter pin, 1.98-inch dust cap, rubber plug, spindle nut, and washer. The listing identifies fitment for 3500 lb #84 spindles and axle dimensions from 1-1/16 to 1-3/8 inches. It was selected for its high set count and broad hardware list.
Limitation: Four sets may be more than needed for a single repair. Check the seal and spindle dimensions against your parts before purchase.
GREPSPUD Four-Set Kit
Best for: Buyers servicing multiple hubs who want listed fitment for a #84 spindle and EZ-Lube axle. The four-set package contains L68149 and L44649 bearings, their matching races, and 171255TB grease seals. The seal dimensions are listed as 1.719-inch inside diameter and 2.565-inch outside diameter.
Each set also includes a spindle nut, shaft washer, cotter pin, 1.98-inch dust cap, and rubber plug. The seller describes the parts as arranged in a cardboard box with bubble wrap to help protect them during shipping. It was selected for its complete hardware list and detailed seal dimensions.
Limitation: Confirm that your axle is the listed 3500 lb, #84, EZ-Lube configuration; axle capacity alone does not confirm fit.
WESTERNPRIME Four-Set Bearing Kit
Best for: Buyers who need four sets of the main bearing components and seals. The package lists four inner L68149 bearings with L68111 races, four outer L44649 bearings with L44610 races, and four double-lip 10-19 grease seals. The seal is listed with a 1.719-inch inside diameter.
This is a more focused choice than kits that also list dust caps, spindle nuts, washers, and cotter pins. It was selected for buyers who want the specified bearing, race, and seal components in a four-set quantity.
Limitation: The supplied feature list does not mention additional installation hardware such as spindle nuts or dust caps. Check whether you need those parts separately.
Misakomo Two-Set Bearing Kit
Best for: A two-hub repair where the listed fit matches the trailer. Misakomo specifies a 3500 lb axle with a #84 spindle, dimensions from 1-1/16 to 1-3/8 inches, and EZ-Lube axle fitment. Its listed contents include L68149 and L44649 bearings, L68111 and L44610 races, 171255TB seals with a 1.719-inch inside diameter, and hardware for two sets.
The kit also includes cotter pins, 1.98-inch dust caps, rubber plugs, spindle nuts, and washers. Separately sealed component bags are described as helping protect stored parts from dust and rust.
Limitation: Choose a four-set kit instead if you need parts for more than two hubs or want additional spares.
XiKe Two-Set Bearing Kit
Best for: Buyers seeking a two-set kit whose listing emphasizes dimensional, noise, and vibration inspection. XiKe lists L68149 and L44649 bearings with L68111 and L44610 races, plus 171255TB seals, cotter pins, and dust covers. It states fitment for trailer axles measuring from 1-1/16 to 1-3/8 inches.
The listing describes chrome-steel bearings and inspection for dimensional tolerance, noise, and vibration. It was selected as a compact alternative to the four-set options.
Limitation: The feature list does not specify spindle nuts, washers, or rubber plugs. Confirm the included quantity and whether you need those items before ordering.
Buying Guide: How To Choose A 3500 Lb Axle Bearing Kit
How do you confirm the kit fits?
Check the axle and spindle specifications, not just the 3500 lb rating. These kits list L68149 inner and L44649 outer bearings, along with corresponding races. Compare those part numbers with your existing components or axle documentation. Also verify the spindle type, including whether it is a #84 spindle or EZ-Lube axle when applicable.
How many sets do you need?
A two-set package is suited to a smaller repair involving two hubs. Four-set kits may suit multiple hubs or provide spare parts, but can include more than a one-time job requires. Count the hubs you plan to service and check the listing’s set quantity before choosing.
Which kit includes the most service hardware?
Compare the contents line by line. iBroPrat, GREPSPUD, and Misakomo list items such as dust caps, rubber plugs, spindle nuts, washers, and cotter pins. WESTERNPRIME lists bearings, races, and seals. XiKe lists seals, cotter pins, and dust covers. Do not assume an unlisted component is included.
Why check the grease seal dimensions?
A seal must match the hub and spindle dimensions. Several listings identify a 171255TB seal with a 1.719-inch inside diameter; GREPSPUD also lists a 2.565-inch outside diameter. Compare both dimensions with your required seal specifications where available.
Frequently Asked Questions
What bearing numbers appear in these 3500 lb kits?
The five kits list L68149 and L44649 bearings, generally paired with L68111 and L44610 races. Verify the numbers against your trailer before buying.
Does every 3500 lb axle use the same bearing kit?
No. Axle capacity alone does not establish fit. Spindle design, bearing numbers, and seal dimensions also matter.
What does a two-set kit usually suit?
It may suit a repair involving two hubs, provided the parts match the axle. Check each listing’s included quantity and hardware.
Are dust caps and spindle nuts included in every kit?
No. Included hardware varies. Review the product’s parts list and arrange any missing items separately.
Should I replace the races with the bearings?
These kits list matching races alongside bearings, but follow the trailer or component manufacturer’s service guidance when deciding what to replace.
