Ctuk in the rear axle gearbox

One of the problems encountered during operation of the vehicle can be a knock on the rear axle gearbox. Knocking occurs, usually at the beginning of the movement, that is, when setting off. Check for a knock on the gearbox is easy enough. Need several times budge (forward and backward) and low (2-2,5 thousand) rpm, with speeds up to 35 km / h and included the second gear, sharply press-release gas. In carrying out these steps, you can hear in the rear axle distinct metallic clatter, which clearly indicates a failure. A knock on the rear axle gearbox occurs, usually due to deterioration of its different parts: a hole under the axis of the satellites in a box, or differential spline connection flange propeller shaft and shaft. Another, not too frequent reason for such a clatter - too big a gap that occurs when the engagement of driving and driven gears. To resolve this problem, you need to replace worn parts, or adjust the clearance of gears. All of these actions require disassembly of gearbox. Perform on their own, without proper equipment and experience, not recommended. Professionals working in the workshop, will this operation faster and better. Often metallic sound coming from the rear axle gear, confused with the sounds of an entirely different nature. For example, like the sound may issue on rough road poorly fixed in the trunk of tools or metal cans. The metal ring can talk about that muffler hurt a beam rear axle or shock As governor spring brake hydraulic drive. Another common cause for the metallic sound coming from the rear of the car - it loose in the slots of the spacer pad strap drive parking brake. This problem can occur even when the parking brake properly adjusted and working properly. In this case, to eliminate the unpleasant sound in the middle of the top contracting spring brake pads can wear rubber hose. The length of the hose should be 12-15 mm and wall thickness - about 1 millimeter. Another solution to the problem - replacing worn parts with subsequent adjustment of the mechanical brake actuator.
