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 ...

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 really simple option is to loosen the nuts while the wheel is resting on the ground, and only raise it up on the jack once they are loose (not removed, just loose) Otherwise, if you don't have brakes you will need to look at wedging the wheel or axle somehow. You can use a strap, or wooden wedges, or as @SolarMike suggested, if the wheel has holes in it,...

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 ...

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 "...

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 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 ...

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 ...

The conflicting advice is confusing to sort out, because the logic seems to have got the cause-and-effect connections wrong. So let's start again... The tires are the only part of the vehicle that is in contact with the road, and that contact has to support the weight of the vehicle. The maths behind that are simple: weight supported by a wheel = (...

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 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 ...

The fact of the matter is any additional load is harder on a transmission. Stuffing 5 of me in four car is 1000 lbs, add say camping gear and you're looking at 1200-1500 lbs of cargo. If my wife were driving alone that'd be less than 120 lbs of carve weight. Over time the difference of just my wife vs 5 of me could be huge, but we're talking over the life of ...

besides the fact that the grease will be messy and get all over everything, the only reason I have seen is that sometimes grease or anti-seize can interfere with a ground connection if there isn't a good ground wire to the trailer lights.

The first thing to check (and think about when using a meter) is where the ground is coming from: Is there a ground wire in the trailer wiring? Is there a good solid connection of the ground wire to the frame of the trailer (or to the ground side of the circuits on the trailer)? Is there a good solid connection between the ground conductor on the vehicle ...

Have you actually tried hooking it up as you suggested and ignoring pin 6 (circuit 54) on the trailer connector? I think it is likely that the trailer is wired with a single filament for the turn signals and brake lights and that pin 6 is not connected. One of the common ways of providing braking on a trailer towed by a car is with electric brakes. Pin 6 ...

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, ...

More than likely, the leds in the light assembly are being over driven for reasonable light output. Typical 5mm and smaller leds, including the typical 5050 or 0805 SMD leds used in these assemblies are only rated for 20mA at their typical forward voltage, and at 12V for the assembly are already over driven. I bought many different models to replace car ...

I think the terms you're using - over-inflate and under-inflate - aren't the best descriptors. There's a maximum tire pressure, around 50 psi for many tires. Inflating past that PSI would be over-inflating - but I don't think that's what you mean by over-inflating. I think you mean, inflating them past what most people inflate them to - around 30 or 35 PSI....

You'll need to know the weight of the trailer and it's maximum capacity (which should be on a plate on the trailer, for any reasonably recent trailer), the maximum towing weight of the car (which should be on the data plate under the bonnet - for a UK spec one it's 750kg unbraked or 1700kg braked), and any restrictions on your licence. It'll then be the ...

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 ...

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 ...

Ok, so as @solar-mike suggested it looks like the converter is is faulty. I did some additional tests so I thought it might be useful to document here what I've done, someone else might be interested in the future. The converter is just a 50x40mm PCB that includes 4x 895-1C-C relays, 1 rectifier diode, 1uF capacitor and a bunch of SMD resistors & ...

There are several things here you're going to need to do: Wheel: You need to replace this. The outside lip looks like it's about done. At the very least it is severely weakened. From what I can see, replacement is your safest and most realistic option. Luckily I don't think these wheels cost very much. If the one on the other side looks the same, replace it ...

The ply rating is a roundabout way to indicate the max. load. There aren't that many plies in the tire (just one or two, normally). You'll want some margin on the max. load, because without a scale it's difficult to estimate how much weight you put in the trailer, and you could overload it or put the load in asymmetrically. There are other parts of the ...

With a weigh carrying ball mount, the hitch carries all the weight of the towed load. Weight distribution uses additional mounted hardware (spring bars) to transfer load to the frame of the tow vehicle itself. In this case the hitch does not bear all the weight like the weight carrying ball mount. According to eTrailer.com: As long as the total loaded ...

If your Sienna's tow hitch looks like everybody else's and just has the square hole with a tongue that slides in and out: use the 350lb. limit(s). If your minivan has some extra hardware that comes out the side of the hitch and looks more complicated, learn more about how to use a weight distributing hitch. These are the differences between life and death ...

No, axles should not be bent. To double-check you would need a known straight-edge, like a level or a "square" (which is actually shaped like an L), and hold that up against the axle(s) If you see light between the two then the axles are not 100% straight. The measuring tool should be pretty long, approximately the same length as the axles. If this ...

Automatic transmissions use a torque converter to allow the engine to turn at a different speed than the transmission input shaft. This allows smooth shifting and it allows the engine to run at idle with the vehicle stopped. The problem is that this device is very inefficient at low RPMs and high torque which causes it to generate a lot of heat in the ...
