Trailer Hub

[Madbigdog2003]

Does anyone know the numbers for a complete hub kit for a 2004 Stratos (EZ Loader) trailer. (Single Axle/5 bolt pattern - under a 2004-386FX Boat)

To answer your query about the numbers for a complete hub kit for a 2004 Stratos EZ Loader trailer (single axle, 5-bolt pattern, under a 2004-386FX boat), here’s a clear and concise response based on a detailed analysis of the specifications:

A complete hub kit for your trailer typically includes the hub, inner and outer bearings, a grease or oil seal, a dust cap, and lug nuts. Since your trailer is an EZ Loader model from 2004 with a single axle and a 5-bolt pattern, it’s most likely designed with a 5 on 4.5-inch bolt circle, a common standard for trailer hubs. The kit’s specific components depend on the axle’s weight capacity, which is influenced by the boat it supports—the 2004 Stratos 386FX, a bass boat approximately 19 feet long.

### Determining the Axle Capacity
The Stratos 386FX, being a 19-foot bass boat, likely has a dry weight of around 1,500 to 2,000 pounds. With the addition of a motor, gear, and fuel, the total weight on the trailer could range from 2,500 to 3,000 pounds. For a single axle trailer to safely carry this load, the axle would typically be rated between 2,500 and 3,500 pounds, with 3,500 pounds being a common choice to provide a safety margin.

### Bearing Sizes and Hub Specifications
- **For a 3,500-pound axle**: The industry standard bearing combination is:
- **Inner bearing**: L68149 (1.378-inch inner diameter)
- **Outer bearing**: L44649 (1.063-inch inner diameter)
These bearings fit a tapered spindle commonly used on trailer axles of this capacity.

- **For a lighter axle (e.g., 2,000–2,500 pounds)**: Some single axle trailers use L44649 bearings for both inner and outer positions, but given the size and weight of the 386FX, a 3,500-pound axle is more probable.

Since your trailer is an EZ Loader supporting a 19-foot boat, the 3,500-pound axle with L68149 (inner) and L44649 (outer) bearings is the most likely configuration.

### Grease vs. Oil Bath Hubs
Boat trailers, especially those from EZ Loader, often use oil bath hubs to protect bearings from water intrusion, a feature common in models from 2004. However, grease hubs are also possible. Without specific details about your trailer’s hub type, an oil bath hub kit is a reasonable assumption for an EZ Loader boat trailer, but a grease hub kit could also apply. The bearing numbers remain the same regardless of lubrication type.

### The Complete Hub Kit Numbers
Based on this analysis, the “numbers” for your complete hub kit refer to the critical bearing components:
- **Inner bearing**: L68149
- **Outer bearing**: L44649

These bearings correspond to a hub with a 5 on 4.5-inch bolt pattern, suitable for a 3,500-pound single axle under your 2004-386FX boat. The kit would also include:
- A grease seal (commonly 1.719-inch inner diameter for a 3,500-pound axle, though this can vary)
- A dust cap or oil cap
- Five lug nuts

### Finding the Exact Part
EZ Loader uses proprietary hub kits, and their specific part numbers (e.g., something like “250-029600” for a 5-lug hub kit) aren’t universally standardized or easily accessible without their catalog. For an exact match:
1. **Check your existing hub**: Look for stamped bearing numbers (e.g., L68149, L44649) or a hub part number.
2. **Measure the spindle**: Confirm the bearing surfaces (1.378 inches for L68149, 1.063 inches for L44649).
3. **Contact EZ Loader**: Provide your trailer’s VIN or model details to their customer service for the precise hub kit part number.

Alternatively, generic hub kits from suppliers like Dexter or etrailer (e.g., #84545UC1 for a 3,500-pound axle with these bearings) may work if compatible with your spindle, though EZ Loader-specific kits are ideal.

### Final Answer
For your 2004 Stratos EZ Loader trailer (single axle, 5-bolt pattern) under a 2004-386FX boat, the complete hub kit likely includes:
- **Inner bearing**: L68149
- **Outer bearing**: L44649

These are the key “numbers” for the hub kit, assuming a 3,500-pound axle. To ensure a perfect fit, verify your spindle measurements or consult EZ Loader for their specific part number.

If oil i recommend changing over to vortex hubs. Does it have any info on the current hubs themselves such as dexter, knott, or ezloader? Alot of times just looking at them can give you some good info to start the search. It usually will give you the manufacturer right on the dust cover. To add just because the trailer is ezloader does not mean they used ezloader bearings..they may haved used knott or tie down engineering or some other manufacturer. After i have figured out which o e that may be i then cross reference that over to vortex hubs and install those..which is my personal preference due to the oil hub problems i have had in the past.

All this off the top of your head, very impressive.

That has to be bad news. Been there!

I asked Grok (X’s AI) - sometimes it’s amazing, other times it hallucinates and lies like a rug.

I’ve replaced the guts
I’ve replaced the whole hub
Last time took it to NW Tire and had them do it. I won’t be messing with it myself again

Hubs are easy if you get the correct ones. They come all together..unbolt nut slide hub assembly off. Make sure spindle looks good. Slide new hub assembly on torque to spec. Add grease and end cap....done. Itd very easy if you get the whole hub assembly. Bearings are already pressed in.

What part of the oil bath hubs fail ? Seems odd because they work flawlessly on 18 wheelers , Iv'e never saw one fail or overheat as long as they have oil.

I have had a number fail and seen a number. Showed a guy at the ramp who said the same thing that his have failed. Its usually the back seal that goes out and leaks oil out slowly making it hard to detect. I believe (with no proof) what causes it is water and freezing tempetures and or hard sharp turns backing up. The tight turn backing up puts some pretty good stress on those seals from what i can tell. My opiniin this is why a number of boats went to vortex hubs..why else if their system worked.
