350z Rubbing Vibration Noise when Accelerating

Strange noise from 350z when accelerating... The beggining you can hear it well but when I put the camera on the dash it's very noticable.. You can hear the normal engine accelerating noise in the background and the hollow type strange noise over it all. Feels like it takes a performance hit too.

You can hear this weird noise everytime you change a gear... The assistance already changed the gearbox unsuccesfully and now they don't know what to do...

Common Noises Your Transmission Might Make
Dallas discusses some common noise that you may hear from your transmission and what you should about it. "Hello again. Dallas Council back from AAMCO Transmissions of Venice and today, I want to talk to you about some common symptoms and sounds that you may hear if you are experiencing a transmission failure. So with that, let's go and get started. If you start your car, put it in gear and it goes, "Graaaaaaaaa-kk!" that may be a transmission problem. If you start your car and it goes, "Wizzzzzzz-zzzzz," that also may be a transmission problem. If when you put your car in gear and give it gas, it goes, Vrooooooooom-Clunk that could also mean that you are having a transmission problem. If when you accelerate, your car goes Vvvvvvvoooooooo and doesn't move very fast, you may be experiencing a transmission problem. If when your car is shifting gears, it goes thddddddth, thddddddth you may be experiencing a transmission problem. If you're driving on the highway and you hear, "Whooooooo, whoo, whoooo," you are probably about to get a speeding ticket. The point of this video was to explain a few symptoms that you may experience if your transmission is failing but more to get the point across that transmissions fail in a variety of ways. There is no set of symptoms that you may experience. Sometimes, you may be experiencing a symptom or noise that you are certain is the transmission and indeed it's really not the transmission. And sometimes you may be experiencing a symptom that you are certain is not the transmission and it may be a transmission failure. With today's transmissions, they're all electronically controlled. They are very hard and can be very tricky to diagnose. Some problems may be minor and not very expensive at all and some problems may be major and be very, very expensive. The best thing to do in any case is to get your car to a specialist or a certified mechanic that will diagnose the car for you accurately because again, there is no common set of circumstances that make one failure major as opposed to one being minor. That can only be determined in real time by a real diagnosis. So again the point of this video was to really have a good time and make you laugh but also get the point across that transmissions fail in a variety of different ways. The most important thing is getting it diagnosed by a trained professional that will save you the most money and get you the best quality repair. So again, this is Dallas Council from AAMCO Transmissions of Venice. Hope you enjoyed and have a great day."

How to Diagnose a Noisy Wheel Hub and Bearing
It can be tricky trying to diagnose a front end suspension noise. We show you a simple technique here simply describing how to diagnose a wheel hub noise. Age, mileage and road conditions can really take a toll on wheel bearings. This particular wheel bearing is a sealed bolt on unit that can only be replaced as an assembly. This procedure can work on many different styles of wheel bearings and front end noises. The automobile consist of: Powertrain: 1. Engine: • Fuel System: Purpose is to deliver fuel to the engine. It consists of the fuel tank, pump, gauge/sensor, filter, pressure regulator and injectors. • Air Intake System: Purpose is to clean and direct outside air into the engine. It consist of air filter, ducts, air plenum and intake manifold. • Exhaust System: Purpose is to direct Exhaust gasses out of combustion out of engine. It consists of the Exhaust manifold, converters, pipes and mufflers. • Cooling System: Purpose is to remove excess heat from the engine. It consists of water pump, hoses, radiator, thermostat, cooling fan and coolant recovery tank. Also the oil system serves as a cooling system as well as a lubricating system. It consist of oil pump, pan, filter and cooler. Drivetrain: 1. Clutch: Purpose is to connect the engine and transmission together. It consists of clutch drive disc, driven disc, release bearing, clutch fork, cable, slave cylinder, master cylinder. There are three types of clutch systems: mechanical, cable and hydraulic. 2. Transmission: Purpose is to match engine speed to road speed. Two types used are manual or automatic. These consist of gears, linkages, cables and converters for automatics. A manual is connected to the clutch by a flywheel and automatic by a flexplate. 3. Driveshaft: Purpose is to connect the transmission to the rear axle. It consists of a slip yoke, shaft and universal joints. 4. Rear axle differential: Purpose is to change the angle of motion from engine to the wheels. It also divides torque between the wheels. It consists of a ring and pinion gear, carrier, bearings, crush sleeve and axle shafts. 5. Wheels/Tires: Purpose is to provide traction to the road as well as carry the weight of the vehicle. Vehicle Control Systems: 1. Brakes: Purpose is to slow and stop the vehicle. It consists of master cylinder, brake Booster (vacuum or hydraulic), calipers, drums, pads and rotors. 2. Steering: Purpose is to direct vehicle in the required direction. Consists of steering gear (rack & pinion), steering wheel, column, inner/outer tie rods, pump, reservoir, hoses and pipes. 3. Suspension: Purpose is to provide stability and handling while also providing comfort to the ride. Consists of shocks, struts, sway bars, end links, springs, trailing arms and bushings. Comfort System: 1: Heating Ventilation Air Conditioning (HVAC): Heats and cools interior air to passenger comfort. Also circulates outside and inside air. • Air Conditioning: Consist of condenser, compressor, accumulator (receiver/dryer) orifice, expansion valve, hoses, evaporator, controls, actuators and modules. • Heating: Consists of heater core, valves, hoses and switches. Electrical Systems: 1. Power Generation: Creates electrical power to run all the electrical systems. Consists of the alternator. 2. Power storage: Stores unused power to start the car and supply voltage to the alternator to create more electricity. • Both systems consist of wiring, harnesses, fuse, relays and modules.
