I often see on the streets Subaru SUV will be labeled instructions tail full-time SUV trailer Do not, why not full-time four-wheel drive car towed it? First we have to understand what is a full-time four-wheel drive, in fact, drive any time, vehicles are driven by four wheels independently.

Still towed by a car with four wheels rotatably connected to the shaft, regardless of which set of wheels to the trailer frame is, and the other wheels are rolling surface friction to rotate, it is easy to center differential wear out faster, the distance long, the consequences will be more serious damage caused.

Inside the center differential gear of four-wheel drive cars attached to the front and rear two shafts, two front wheels when the trailer is typically suspended, behind the wheel, a difference is generated between front and rear axles so that a rotational speed difference, the center of gravity will fall in the center of the tachometer, if it is a multi-disc clutch in the center differential will generate a lot of heat, but this time the car did not start, can not dissipate the heat, it will cause damage to the turbine, gear and if the time is hanging in P position, clutch and engine to the wheels stuck, and did not tell truck drivers, auto parts Shenglayingzhuai very likely to cause damage. So now the trailers will be pulled back completely and four wheels in the back of the tablet, do not let the wheels hanging.

So AWD owners at the end of last labeled prompt, then it could be towed away because when parking the tow truck driver, tow truck driver to remind, the right way to drag a different car to prevent damage.
