AT Horizon Hub Modification and a few others (1 Viewer)

[Romer]

It's nice when you have a trailer to be running the same tires and RIMs as the tow vehicle so you only have to carry one spare tire.

I recently bought an AT Horizon, but it had Jeep Hubs and 33" Tires. I wanted to be able to use my 35" Tires on Toyota Rims.

I went to a local trailer shop and bought a 10" Dexter Toyota Hub with the bearings and seals.

You can re-use the existing bearings, but need to replace the inner seal. The new bearings were fairly in-expensive ( Compare to cruiser bearings) so I bought new. This also allows you to set up the new hubs and have them ready for a quick swap.

My trailer has the 3500lb Torsion bar Axel set up

The first thing of course is to remove the tire and the axle dust cap

Next, bend back the tang on the lock washer and then loosen the retaining nut

 

[Romer]

With the nut removed, remove the old Hub

Pack the new bearings.

I use Mobil 1 Bearing Grease and roll the bearings in my hand till it is well into the inners of the bearing. You want to see grease come up through the inner ring

Tap in the inner axle seal and ensure it is fluch with the inner part of the Hub.

I also put some grease on the inside part of the hub that goes on the spindle

 

[Romer]

Put the new hub on

Install the outer bearing that is also packed with grease

Install the lock washer

Add the lock nut

 

[Romer]

Now you need to tighten the lock nut until you can't turn the drum. This will set the bearings and seals in place.

Then loosen so the drum turns freely, but not to loose.

For those cruiser guys who do their own front axles, I used the fish scale method and set the pre-load to about 10lbs. Never done this before on a trailer, but it seemed about right to me

Then push the tab from the lock washer into place

Install the tire an torque the new nuts.

You can replace the Dexter bolts with Toyota's so you can use the same lug nuts if you want

I also installed the ARB Fridge Slide.


Lesson Learned: I installed it to far to the right so I had to modify the right latching mechanism

 

[Romer]

I then installed the Battery Charger and shore plug so I could charge it off of 110V rather than just the truck

 

[Romer]

Now I just need to swap the RTT for the one I want and I am set.

May want to get larger or at least a spare Propane tank and come up with some kind of heater system

Just a little easier than a birf job on the cruiser Ken? Time to start a FAQ/Mods section for trailers now too!

Very nice write up Romer, thanks for taking time to document the steps and take pictures.

Can't wait to see some camping pics!

Good luck, Pat

To keep this complete on my buildup, my Eezi-awn globetrotter install is here
I installed a Eezi-Awn Globetrotter on my trailer and did a full write-up on the portal

Eezi-Awn Globetrotter on a AT Horizon - My selection and install - Expedition Portal Forum

Installed Dual Batteries in the trailer today using two of the Deka Blems I bought. For the trailer I elected to use a Marine Rotary switch. You can find great stuff for batteries, terminals and manual switches at Marine Parts stores.

I have a 10amp charger that connects to wall power and will fully charge a single battery in 7-8 hours. Since It will be parked for days at a minimum between trips, I did not upgrade this to a 20 amp charger.

Removed the old battery (Lifeline 31 AGM)

Installed second battery tray

Wired up switch and installed

Installed both batteries and hooked them up.

Fairly simple and quick install

I will charge and drive with the switch in the both position.

When I get to camp, I will turn it to position 1. Based on my load, I expect it to last 3-4 days. I will then switch to position 2 and have a fresh battery.

I am going to test it over the next week with the fridge running and some other things and see how it does.

Debating on installing a voltage monitor to be able to tell how the batteries are doing. Probably will.

If I run out of power, I would just hook up the truck and recharge or find a 110 outlet.

Snap Ken, that looks great man. We gotta' go out for an overnight run somewhere scenic a quiet! I really dig your horizon, what a tremendously well built little rig.

Did you use the lug nuts that came with the hub? My FJ Cruiser wheels seem to have a really large hole for the stud. The OEM lug nuts are a "mag" style and not "acorn" like the ones that come with the hubs. I can't seem to find the "mag" style with the correct thread pitch for the new hubs.

 

[Romer]

I swapped out the white tank for the Black one and handpump and installed the Sink setup

Of course you take the sink off when driving

Not really a trailer modification per say

I bought an LED light from AT that can be attached to the camper or used on the truck as a reverse light.

I struggled with where to mount it as I envisoned being able to use it in multiple places.

Over a beer and Cigar I came up with an idea.

Why not mount it on a stake with a long plug to the aux outlet, then I could move it around

Bought the stake at Harbor Freight.

Over a beer and Cigar I came up with an idea.

That had to have been one BIG beer or one SMALL cigar??? Good job.

How are you going to plug all the stake holes in the trailer?

 

[titanpat57]

Here's a challange Oh Gifted One.....


Make a dual pupose jammi...something that fits on a stake AND...

can be removed and connected to a magnet to stick to the trailer, if need may be

But thats why it takes me forever to do something...wheels won't stop long enough to just execute...lol

Cheers!

Sold it already

RATS!

Thanks for the reply just the same! $445.00 for the AT tank is just a bit too rich for my build!!

Cheers
