I have the split trailer from harbor freight, but the wheels is 4 lugs. What did you do to adapt the jeep wheels? CAn you show us? I really like your project and would like to try it myself. I never done this before. any recommendations would help. thank you.
David,
I used the HF 94564 1720-lb. capacity trailer, which comes with a 5-lug, 5-on-4.5 (same as the Jeep) bolt pattern on a 2000-lb. capacity axle. All of the other lighter capacity HF trailers, like yours, come with 4-lug hubs and a lighter-duty axle.
There are several ways to change your trailer to 5-lug hubs, but before I list them, a word of caution - the axles that come with the lighter-duty HF trailers are made from light-gauge sheet metal folded into a u-channel, see the HF drawing clip below. This axle is designed for loads under 1500-lbs. total and 12" tires. Putting Jeep-sized tires on that axle may cause forces that exceed the strength of the axle. Use good judgement in whatever you do with the light-duty HF axles.
So here are some ways to do it:
1. Wheel adapters. The only wheel adapters I've seen that go from 4-on-4 to 5-on-4.5 are designed for golf carts, so perhaps not heavy enough for road trailer usage. If anyone else has a source for heavier-duty adapters, I'd be interested in hearing about them. I can give you a link to the golf cart adapters, but I hesitate to post it because I don't know if they'd really be up to the task.
2. Replace the hubs. Unfortunately since the HF axles are metric, and pretty much all of the 2000-lb. 5-lug replacement trailer hubs you'll find in stores like Tractor Supply are designed for either 1" or 1 1/6" axles, you might have trouble finding hubs or bearings to fit. However, the 4-lug and 5-lug HF hubs all take the same bearings and axles, so you could order replacement 5-lug hubs from HF nd swap them on, you could even reuse your current bearings (although the bearings are not very expensive so maybe a false economy). Here's a clip from the 94564 trailer assembly manual, you could call the HF 800 number with the 94564 kit # and hub part # (18) and see how much replacements would cost. But you'd still have the cheesy sheet metal axle.
3. What I'd recommend is getting a new axle, and I'd recommend it for two reasons - first because you'd be replacing the cheesy sheet metal axle, and second, you could get the axle made a bit wider so you could actually fit Jeep-sized tires on the trailer without them rubbing the frame - take a look at your trailer and you'll see there isn't much clearance between the tiny 12" tires and the frame rails, you won't fit a wider Jeep tire on there.
A complete replacement axle with hubs can be had for as little as $102 (

You didn't specifically say you wanted 5-lug hubs so you could run Jeep wheels and tires, but one more note - if you're thinking of running Jeep Wrangler factory alloy wheels, the center hole in those wheels is too small to fit over the entire trailer hub, so you'll need 1.25" 5-lug spacers to space the wheel out enough so the tiny center hole clears the hub.
You'd have to do specific measurements for the tires/wheels you planned to run, but if you ordered a new axle with the spring seats the same distance apart as the springs on your HF frame but the axle itself being 4" longer figuring 1.25" spacers would also be used, or perhaps 7" longer if you wanted to run Jeep steel wheels, you'd pick up enough length to clear the frame with Jeep-sized wheels and tires.
If you need any more info let me know.
