Loud banging from rear suspension of Ford e350 cutaway van single wheel rear not dually.

I have a e350 cutaway 4×4 shuttle bus. It has leaf spring rear suspension. Whenever I go over little bumps or changes in road level (i.e. going from dirt to pavement or construction) there is a loud bang that sounds like something hitting the frame of the bus. I currently don't have much weight over the rear axle and was wondering if it had to do with that or possibly a bump stop? The rear suspension has not been modified besides a lift block.

My car has 95000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Look at the suspension on the rear of the van and see if there is anything that looks broken. If not, then the bushings on the shackles on the leaf springs could be damaged causing the leaf springs to shift when going over bumps causing them to bind up. If not, then the leaf springs could be cracked causing the spring to be weak and making the spring bumper hit the frame. If you need further assistance with your suspension making a banging noise on the rear, then seek out a professional, such as one from Your Mechanic, to help you.

Conversely, a noise that is louder when the vehicle is coasting, probably means there is not enough tooth contact (too much backlash). 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.
Gear Grinding: Humming noises and gear grinding can also indicate an issue with your rear differential. Rattling While Idling: If you turn your vehicle on and put it into drive, you may rear a rattling noise coming from the rear of the vehicle. This could be a sign of a bad differential or driveshaft joint.
Only difference between a wheel bearing noise and a rear differential noise would be the fact that the wheel bearing noise will change with wheel speed but usually will not change with load variations (accelerations/decelerations) while the noise from a rear differential will change with wheel speed and load.
FoMoCo representatives tell Ford Authority that skipping a model year was done in an effort to boost the residual values of existing vehicles. In theory, skipping a model year would allow the new model year – in this case the 2021 Ford E-Series – to remain current and more valuable, for a longer period of time.
Symptoms of a bad differential

A howling noise when you accelerate – May be caused by a worn pinion gear, worn ring gear, or an improper fitment. A whirring noise when decelerating – May be caused by loose or bad bearings in the pinion gear or ring gear. Noise when cornering – May be caused by broken spider gears.

If you hear a clunking noise from the rear of your car while driving, it`s likely the rear suspension system. As cars get older, the suspensions start to loosen which creates a clunking and rattling sound while driving.
A “whirring” sound generated by unloading via deceleration from most any regular road speed can likely be traced to pinion bearing failure or poor pinion bearing preload. This malady is often diagnosed as a bad ring and pinion gear.
A bad wheel bearing sound is usually a loud hum coming from that wheel sort of like loud road noise from bad tires. A similar noise can come from worn bearings in your transmission or even a low transmission fluid level.
While there is no help for our singing, we can help you diagnose the sounds coming from a differential gone bad. A clunk, whine, or howl can signal a worn-out pinion gear, bad pinion bearings, or a faulty gear installation.
Ford Model e will primarily deal with electric and connected vehicles, while Ford Blue will become the automaker`s dedicated arm that will prioritize cars with an internal combustion engine. The decision to split Ford into two businesses is part of the Ford+ plan that Farley announced last year.
The Ford E-Series (also known as the Ford Econoline, Ford Econovan or Ford Club Wagon) is a range of full-size vans manufactured and marketed by the Ford Motor Company.
A tell-tale sign that this bushing is no longer performing as intended is hearing a clunking noise or feeling a jolt under acceleration or when shifting gears from drive to reverse.
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.
Rattling noises that appear when you`re driving over bumps, or on uneven surfaces, are often down to the suspension. These rattles can disappear once you speed up a bit or when the going gets smoother. The culprits may be the drop links (e.g. if they`ve snapped), worn bushes or corroded shock absorbers.
That clunking noise you hear from the front end of your car when driving over a bump can be telling of an issue with your car`s suspension. More specifically, the problem is with your control arms or suspension system struts. This damage can occur if you are off-road or roughly going over potholes.
Sometimes creaks in suspension and steering systems are down to a lack of lubrication between metal components such as tie rod ends and shock units. A properly lubricated system will also prevent significant build-up of dirt.
Believe it or not, transmission damage from a rear-end collision is not that uncommon. Some cars are more susceptible to rear-end transmission damage, such as those with rear or all-wheel drive because the car`s transmission is actually a bit further back in the vehicle.
When a wheel hub bearing wears out, it puts extra stress on the CV-joint. That can cause the knocking/clunking noise when you turn the vehicle.
Driving with worn wheel bearings can cause serious damage to your drive-axle and steering assembly and ultimately be a major safety hazard. Driving on a bad wheel bearing puts stress on the hub and CV joint, brake system components, and ultimately on the transmission itself.
If the wheel bearing is in bad shape, we will hear a grinding sound regardless of the speed we are driving at. The noise will speed up at the same rhythm that the car does and it gets louder or quieter when cornering, depending on whether the cornering inner or outer wheel bearing is defective.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

Very Loud Knocking noise from left rear wheel when turning left and braking
ANSWER : The problem could be in the transfer case unit, but the device is mounted closer to the driver than the rear wheel so the noises or vibrations are generally a little more obvious. Especially during sharp turns the transfer case and rear end assemblies are working pretty hard with the wheels turning at different rates. I suggest hiring one of our mobile experts to diagnose the noise you’re hearing. Wheel bearings and worn out suspension components like sway bar links cause similar noises.

Loud bang from front wheel and the wheel locks up in reverse. It didn’t show signs of a bad cv shaft. binding or hub bearing?
ANSWER : Hitting a pothole can damage wheel bearings. Basically, the force of the impact causes the ball bearings to get driven into the bearing race and cause indentations in the race. Then the bearing eventually becomes noisy. You could have damaged the bearing but the other noises (loud banging, as you describe it) and the binding of the axle may indicate other or additional damage. The only way to identify the damage, and determine the cause of the axle binding, is to inspect what you have. If you request a suspension inspection a certified mechanic will inspect the car and estimate the required repairs. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

My right rear wheel on my rear wheel drive 2008 Dodge Charger sticks sometimes when I ty to accelerate
ANSWER : Hi there. When the wheel stops spinning or is sticking while accelerating, it’s usually caused by one of three problems. Either the ABS system is malfunctioning, the brake caliper is sticking or the wheel bearing is damaged. Either of these issues are considered to be safety hazards, so I would strongly recommend having a professional mobile mechanic come to your location and complete an inspection to determine the source of this issue and recommend the right repairs.

All wheels are slightly bent and one wheel is cracked
ANSWER : When the vehicle’s rims develop these type of cracks, they should be replaced immediately. The cracks can make the wheel unstable and should not be driven on until it is repaired. The most common causes of trims cracking in this manner is due to potholes or other impact damage. The wheels may have a fault, if they have all failed at once. A qualified technician, such as one from YourMechanic, will be able to inspect your steering, suspension, and wheels in order to diagnose this fault.

How to make front wheel drive car to a rare wheel or all wheel drive
ANSWER : You would be better off trading the vehicle out for a vehicle that has all wheel drive. There is no way to add the additional drive you want.

I hear an abnormal noise from front driver’s side wheel. It sounds like a wheel bearing but not sure.
ANSWER : A wheel bearing noise can be different between vehicles as some designs may vary a little. The most common is a roaring noise that may change when going around turns. It may be louder going in one direction or the other or just make a loud noise all of the time. The wheel hub presses into the wheel bearing. The hub is where the studs are for the wheel to be bolted onto the steering knuckle and the bearing provides the support for the wheel and weight of the vehicle. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at your wheel bearing noise to offer a more personal diagnosis.
