There is a clunking sound coming from the rear of the car

My car rides rough on the street when hitting bumps. I think it may need shocks and or struts. It sounds like something is loose under the car with a clunking noise from the rear. I recently had the exhaust pipe fixed that had broken at the catalytic converter but the noise had been there before that. There is also a problem when stepping on the gas from a stop there is a loud roaring sound for a few seconds until the car accelerates. It's like it's struggling to accelerate but I don't hear the noise again until I start again after stopping at a light or stop sign.

Experienced mechanics share their insights in answering this question :
Hi and thanks for contacting YourMechanic. The struts or shocks could be causing a rough ride, but the looseness under the vehicle is a suspension part that is loose. Check all of the suspension for any broken bolts or damaged bushings.

The problem with the accelerator is a transmission issue that is loading up the vehicle’s engine. It sounds like the torque converter has a stator issue and is not multiplying torque. If you need assistance with the vehicle’s suspension or transmission, then seek out a professional, such as one from YourMechanic, to help you determine the source of the clunking noise and perform an inspection of the suspension system.

A knocking or clicking sound may be due to the splines on the axle shafts being worn out, in which case the defective shaft has to be replaced. Another reason for this may be chipped teeth on one or more of the gears in the differential. Again, they`ll need to be replaced.
This is not an uncommon fault. The most likely causes would be low transmission fluid, a shift solenoid, transmission mounts, or a drive shaft. Your best bet may be to have a qualified professional, such as one from YourMechanic, take a look at the car in person in order to diagnose and repair your acceleration issue.
If you hear a clunk when the suspension works over bumps, you may have excessive clearance in a joint due to wear. It might be as simple as a loose nut on the strut, or something more subtle such as a shrunken, dried-out rubber bushing.
A car that makes a clunking noise when you start the engine usually indicates either a starter failure or broken teeth on your transmission`s flex plate. Starter motor replacement is not too big a job, though it is likely to take a mechanic several hours to complete.
A squeaking sound that speeds up as you accelerate

If you have four-wheel or rear-wheel drive and hear a squeaking sound as you hit the gas, the culprit is likely to be a failing universal joint (U-Joint), which is a component of the driveshaft.

Loud squeaking or squealing noise while accelerating could mean there`s a problem with your engine belt. It could mean the belt`s loose or worn. Or it could mean that one of the belt`s pulleys is starting to fail. Loud rumbling noise when accelerating might suggest there`s a problem with your exhaust system.
You might have carbon build-up in the combustion chamber. This one really needs a mechanic`s attention. A deep knocking noise can be an indication of a possible catastrophic failure. First check your oil – then bring it in and have it evaluated.
If you have an automatic transmission and your transmission fluid is low or if it is too old, it could start making a clunking noise. This is because there isn`t enough lubrication and cooling for the different parts of your transmission. It could also mean that your transmission is failing.
Some worn-out struts (but not all) will make noises that can alert you to their declining state. Bad strut sounds are usually described as a hollow clunking or banging type of sound. You`ll typically hear the noise when the vehicle is traveling over irregularities in the road.
There are four sounds in particular that you should look out for: creaking, grunting, rattling, and knocking. See your auto collision center if you hear any of these noises, and keep reading for more on the four sounds of suspension problems.
Buildup of Carbon Deposits

Commonly, engine knocking occurs because of a buildup of oily carbon deposits inside the combustion chamber. This can be caused by burning oil or incomplete combustion from misfires, which coats pistons, cylinder heads, and other parts of your engine with residue.

A clunking, rattling, or squeaking noise from your front end while driving can be annoying and unnerving. Oftentimes, this noisy symptom means there is a problem with your vehicle`s suspension system. These sounds typically occur when driving over uneven surfaces, bumps, or potholes.
If the engine mounts wear out, they cannot stop your car`s engine from moving around while you`re driving. When you press down on the gas pedal, your engine can come into contact with other metal components under the hood. This can result in a rattling sound from under the hood any time you accelerate.
There`s a Problem with Your Brakes or Wheel Bearings

A number of brake problems can cause a helicopter-like sound while driving, including a warped caliper or rotor, issues with the parking brake, or just a bad brake.

If your car struggles to accelerate, you might struggle to change gears or the transition can feel rough. It might feel like a jerk, clunk or thud. This is usually caused by troubles with the vacuum, transmission fluid or a faulty sensor. The vacuum modulator valve helps older vehicles determine when to shift gears.

When I turn on my AC the radiator fans do not turn on. The fans do come on when the car warms up so I know they are working and the fuses are good. The AC compressor does come on and the air blows ice cold when the car is moving. Car is a 2006 Chrysler Sebring Sedan 2.7l v6.
ANSWER : The control circuit for the fans needs to be checked. For example, there is usually a condenser fan relay in the A/C electrical controls. There could be a fault with that relay and/or wiring problems, perhaps even just a loose connection, blown or loose fuse, and so forth. To resolve something like this, the recommended service is an electrical component diagnostic. If you request that diagnostic service, the responding certified mechanic will get the problem pinpointed and resolved. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Car sounds like golf cart when revving and braking; also leaking fluid; sound fades as car warms up
ANSWER : Hello,
There are a number of things that could make an engine noisy when starting up. Depending on the specific type of sound you are referring to, this will determine how to properly diagnose. If there is a bit of a hissing sound, this may be a sign of a vacuum leak. If this is more of a shrieking sound, this may be a sign of a worn out or out of adjustment serpentine belt. If there is a bit of a howling or growling sound, this may be a sign of a worn out or low on fluid power steering pump. A rattling or pinging sound may be caused by an ignition problem. An engine can ping (or knock) due to an improper combustion process. A "spark knock" is the result of combustion occurring too early. Early combustion can occur from carbon buildup inside the combustion chamber, a lean air/fuel mixture, and advanced ignition timing (spark plug firing too soon). A clattering type sound may be a result of improper lubrication in the valve train which could be a more serious problem and should be addressed as soon as possible. I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle to ensure everything is in proper working order.

A large clunking noise is coming from the front left of my car anytime I start my car, and anytime I go over a pothole/speedbump
ANSWER : Hi, thanks for writing in. If simply starting your car causes a clunk, then you may have another damaged motor or transmission mount (there are 4 total). You should replace all 4 mounts. When one mount fails, it allows excess motion of the engine/transmission, damaging the other mounts as well. It is false economy, generally speaking, with the age and mileage of your Honda, to do them one at a time. If you would like help with these replacements, consider having an expert automotive technician from YourMechanic come to your home or office to perform the engine mount replacements for you.

Charging warning light comes on when i turn the key and try to start the car and the car want start but when someone tried to give
ANSWER : Hi there:

If you recently replaced your battery, the issue may be caused by a malfunctioning alternator or other electrical component that comprises the charging system on your Nissan Sentra. The best way to find out which item specifically is faulty, is to have a professional mobile mechanic complete a car is hard to start inspection. This will allow the mechanic to determine the precise source of what’s going on with your Sentra and recommend or complete the right repairs.

When I drive it and come to a stop with my foot on the brake my car revs up and sometimes shuts off and I have to start up again 2006 Chevrolet Impala
ANSWER : Hi – first task is to read any problem codes, whether the Check Engine light is on or not. Most auto parts stores will do this for you for free on a "time-available" basis. Any codes extracted are useful for diagnostic purposes. Based on your symptoms, the throttle position sensor is a leading failure possibility. A malfunctioning idle air controller could also cause the unpredictable idling issues, but not a shut-off while driving. I recommend a car stalling inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

Popping sound coming from rear of vehicle at low speeds
ANSWER : The noise sounds like the rear brake drum is warped which will cause the brakes to grab and release, causing the noise. Have the rear brakes checked and resurface or replace the drums. If you have rear rotors and disc pads then the problem is most likely the rear rotors are warped and need to be replaced.
