What Causes Rear Wheel Play in Jimny?

Reasons for rear wheel play in Jimny include bearing clearance and wheel clearance. Below are the solutions for rear wheel play in Jimny: Bearing Clearance: Rear wheel play is caused by bearing clearance, which results from wear of the bearing balls. Excessive clearance can lead to uneven tire wear on the rear wheels and loud bearing noise, requiring bearing replacement. Wheel Clearance: Open the front wheel steering knuckle front cover and remove the axle hub lock nut pin. Rotate the nut and move the wheel to feel the amount of play (or rotate the nut by 1/4 of the thread pitch, typically achieving a clearance of 0.25-0.35 mm). After adjustment, tighten the lock nut to complete the process. For the rear wheels, adjustment is done via the nut on the axle tube, similar to the front wheels.

What Causes the Steering Gear Noise in Subaru Outback?

Steering gear noise in Subaru Outback is caused by the reduction gear noise, rack and pinion noise, and end bushing noise. Reduction gear noise: This is mainly due to excessive clearance between the worm and worm wheel of the reduction gear, causing the teeth to collide and produce noise. The solution is to increase the amount of grease in the reduction gear by injecting special steering gear oil to fill the gap. Rack and pinion noise: This is primarily caused by excessive clearance between the rack and pinion. It requires replacing the improved reinforced spring and shim, then adjusting the clearance to resolve the issue. End bushing noise: This is mainly due to excessive clearance between the end bushing and the rack shaft, causing the teeth to collide and produce noise. The steering gear needs to be replaced.

What Causes the Lavida to Have No Response When Accelerating?

Lavida's lack of response when accelerating could be due to sensor failure, computer control system failure, unstable oil pressure, and other reasons. Sensor Failure: Throttle position sensor failure, acceleration sensor failure, thus unable to receive acceleration signals. Computer Control System Failure: Engine computer control system failure, unable to effectively send acceleration signals, communication issues, throttle body being too dirty causing sticking, etc. Unstable Oil Pressure: Such as abnormal oil pump pressure; clogged gasoline filter; blocked oil lines or excessive impurities; injector quality issues or affected by foreign objects, excessive impurities leading to poor or no fuel injection; incorrect fuel grade, excessive water content, excessive impurities, etc. Ignition system components like distributor, ignition coil, high-voltage wires, etc., malfunctioning; spark plug ignition failure, poor or no ignition, resulting in no response when accelerating.

What brand are the original tires on the new Excelle?

The new Excelle models come with different tire brands, including Goodyear and Giti. Tires are ring-shaped elastic rubber products mounted on various vehicles or machinery for ground rolling. Tire functions: Usually installed on metal rims, they support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain driving performance. Tires operate under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during use. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption. Goodyear introduction: Goodyear is the world's largest tire manufacturing company, headquartered in Akron, Ohio, USA. The company primarily produces tires, engineered rubber products, and chemical products across more than 90 factories in 28 countries. Its tires are known for being relatively wear-resistant.

What is the method to reset the maintenance light on an Audi Q5L?

Audi maintenance is generally performed once a year or every 10,000 kilometers. Car Maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Audi Q5L Maintenance Items: Replace engine oil and oil filter, visually inspect the engine for leaks or damage, visually inspect all components related to exhaust emissions, check the exhaust system for leaks or damage, check the concentration of coolant/antifreeze, add coolant or adjust concentration if necessary, query the self-diagnosis system fault memory, check the thickness of brake friction linings, visually inspect the brake system for leaks or damage, check the brake fluid level based on the wear status of brake friction linings, visually inspect the transmission, final drive, and constant velocity joint boots for leaks or damage, check the steering ball joint dust boots for leaks or damage, check the tread depth and wear pattern of all tires, check tire pressure and adjust if necessary, check the battery electrolyte level and add distilled water if needed, check the steering tie rod end joint clearance, tightness, and dust boot condition, check the air reservoir and drain valve for cleanliness and clean if necessary, check the lubrication of door locks, safety locks, and child safety lock functions, check the functionality of lighting, turn signals, hazard warning lights, warning/indicator lights, and horn, check the functionality of windshield wipers/washers, headlight washers, washer nozzles, and the wiper stop position.

Why is the car air conditioning not cooling at idle but cools when driving?

The reason why the car air conditioning does not cool at idle but cools when driving is: insufficient refrigerant, severely clogged air filter, dirty condenser, faulty air conditioning compressor, damaged expansion valve, or loose air conditioning belt. The solutions are to add refrigerant; check the pipelines, air conditioning pump, condenser, and evaporator in the car air conditioning system for any damage causing refrigerant leakage; inspect the compressor; clean or replace the air filter. Compression process of car air conditioning working principle: The compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator and compresses it into high-temperature and high-pressure gas, which is then discharged from the compressor. Heat dissipation process of car air conditioning working principle: The high-temperature and high-pressure superheated refrigerant gas enters the condenser. Due to the decrease in pressure and temperature, the refrigerant gas condenses into liquid and releases a large amount of heat. Throttling process of car air conditioning working principle: The higher-temperature and higher-pressure refrigerant liquid passes through the expansion device, causing its volume to increase, and its pressure and temperature drop sharply, discharging from the expansion device in a mist form (fine liquid droplets). Heat absorption process of car air conditioning working principle: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into gas. During the evaporation process, it absorbs a large amount of surrounding heat, and then the low-temperature and low-pressure refrigerant vapor re-enters the compressor. This working principle process repeats continuously, thereby achieving the purpose of reducing the air temperature around the evaporator.
