The duct pipe of the sonant is one of the weak points of Chevrolet Niva. The oil from this tube may be displayed even under a small mileage. In the case of the final cliff, the tener is no more involved in the chain, which may lead to its retaking.
A good alternative is the automatic tenor of the Pilot. If it is not possible to change the mechanism completely because of the warranty service, you can replace the wheel tube with the brake pipe.
