Brake performance, or vehicle stability, not motive power are the primary concerns with trailer limits. Why no trailers in early hybrids? Several considerations; first is the battery. In hybrids with regenerative braking the electric motors act as generators producing electricity. Now that electricity has be put somewhere; it goes into the battery. But ...

Here is a diagram for the basic 4 wire trailer. Yellow - Left Stop/Turn (the big filament as you described in the left bulb) Green - Right Stop/Turn (the big filament as you described in the right bulb) Brown - Parking/Marker lights (the small filament as you described in both the right and left side bulbs) White - Ground They all hook to the ...

First is to soak them with a good penetrating oil like Liquid Wrench, PB Blaster or Sea Foam. If you have access to an impact wrench, electric might work but pneumatics tend to have more torque. If you don't own one consider renting one or purchasing one from a store with a liberal return policy. If that is out of the question slide a pipe, crow bar, large ...

The issue most likely is, the trailer was empty. The brakes are designed to work well when the trailer is full. As you can imagine, if the dump was full of loose gravel there'd be quite a load in it. When the trailer is empty, the same amount of force on the brake pedal can cause the brakes to lock up easily. This is something more for the driver to worry ...

It sounds like you have a ground issue. When the running lights are on they are actually grounding through the brake lights. When you apply the brakes it cuts off the ground and the lights go out. The turn signals only look like their working. They are probably turning on and off when they should be getting brighter and dimmer. Double check the wiring on ...

Many older cars with a tow ball had no electrical outlet - back in the day regulations weren't as strict on adding lights to trailers etc. Many modern cars either have an outlet, or have a factory option for adding one. Typically, Camry's from about 97 or 98 have a panel you need to remove inside the trunk. This does vary a bit between versions, but this ...

The following applies to wiring basic rear lights for an un-braked trailer. Wiring up tow-bar electrics is fairly simple if you have a few tools, even if the car doesn't have a connector specifically for a tow-bar connection. You need not know the colour scheme of the car's wiring either. Each pin on the tow-ball plug goes directly to the positive wire ...

If the dump box gets pushed on by a truck or an end loader or whatever, it can cause damage to the box, possibly not even allowing it to dump again. The rear door, while seeming stable to you and me, would be at the mercy of an end loader or bulldozer. Some might want to push the box to get the truck to move, such as if it got stuck or needed a little extra ...

My first thought is that the trailer brakes are correctly adjusted and the trucks are out of adjustment. Excessive pedal pressure (movement) is required to engage the truck brakes. This over brakes the empty trailer causing the lock-up.

The nut you are referring to is meant to be welded in place. The bolt then threads into and out of this nut without it moving. What you have run in to is that the bolt is so rusted in the nut, that it broke the welds and now the nut is spinning. The bad news is that they don't make special tools for welded nuts. A set of locking pliers sometimes called ...

When you install a new connector, coat the exposed metal surfaces with dielectric silicone grease. This will keep out moisture and slow corrosion. You can also just squirt the stuff in to the connector. It might be messy, but things will still work fine.

It depends on the size of the spindle and whether it is a straight spindle or not (more than likely it is straight). There are two common sizes for small trailers (I believe). It should be the A14 bearing set for the 1" spindle, or A6 set for the 1 1/4" spindle. If in the US, you should be able to pick these up from any of the major parts stores (AutoZone, ...

What's the tongue weight on that box trailer when it's loaded? From the configuration, I'm betting it's pretty seriously heavy. Might even be a chore to lift the tongue by hand when it's empty. Assuming that's the case, I'd lean pretty hard towards either a half-ton pickup or a full-sized van. I've towed a horse trailer configured like that box trailer ...

The bed of a dump truck is only secured by two hinges and a Hydraulic hoist. It is not designed to be pushed by a wheel loader bulldozer or other piece of equipment in the event it becomes stuck. An aluminum bed could easily be crushed just from the extra force imposed upon the tailgate, And in the least case scenario would be severely misaligned thus ...

With trucks whether they are tandem trailer (A or B trains depending on the size of trailers) or not have air brakes. Sometimes they develop leaks in the air lines. When the pressure drops below a certain value the trailer brakes lock up suddenly. I notice you didn't mention smoke from the front trailer. I suspect it was normal stop but the rear trailer had ...

For the most part, it sounds as though your ground is dead. Trace the ground wire back to where it is connected to the frame of the trailer. You'll probably find that it is corroded where it's connected and it isn't getting a proper connection. It should be the green/brown wire on the right hand side in the second picture. Disconnect the ground at the frame ...

You need to look at the maximum rated towing weight for the car - this is the weight that car car can pull, and stop, safely (though not necessarily quickly or economically). I don't know about the US, but all manufacturers selling cars in the EU are required to calculate this, and stamp it on the VIN plate. This weight needs to be more than the maximum ...

Get a Diesel pickup. They're much nicer these days than they were 20 years ago. Or something with at least a V6 engine and RWD.

Caravan and trailor manufacturers use a variety of brands for brakes, axles and hubs stubs and rims. These could be surplus car items or purpose made for trailers. For example Trojan http://www.trojan.co.nz/stub-kits-disc-c-23_26.html Some details about the make, model, year, and country of origin of your caravan might help identify them. Also photos of ...

If it was me, I would buy the HF trailer with the 12" wheels, put a deck of 3/4 ply on it, bolt a front wheel chock to it, screw down some rear wheel blocks, strap it tight and pull the trailer. Total cost about $400 and you can sell the trailer for at least $300 at the other end. I've done just that with my much heavier R1100GS and it did PA <-> FL a ...

This would depend a great deal on the load carried and the tyre pressure. The tyres will Flex and bulge somewhat and can fail if allowed to rub against the chassis. My trailer has a couple of inches clearance.

You can ground your test light at any place where there's a good ground. That might be a bare nut/both, off the leaf springs, on a rust spot on the bumper ... anywhere. There are two types of connectors I've seen for smaller trailers (4 way or 7 way). If you are using the 4 way, I've seen if you twist the two connectors together (work them back/forth ...

Nice list you've put together so far. If you don't tow often, double-check the registration on the plate. Inspect Trailer Tie-Down Locking Mechanism, and Materials. You're looking for cranks that physically won't turn (due to rust), worn straps due to friction or chafing, or broken hooks or loops on the object being towed. Are your wheels self-greasing? Do ...

I haven't used one of these, so I can't speak from personal experience, but this connector looks promising. I found a review of the connector, I have no idea how independent it is, but it goes into the build details.
