The Ford expedition of the late 00s and early 10s were commemorated for their responsive and comfortable wait suspension systems. However, the lifespan of this systems has actually proven to be an issue.For starters, like all waiting suspensions, the expectation of the Ford expedition is limited. The is guaranteed to fail at some point.Let’s discover some of the factors why this Ford exploration air suspensions fail as often as they do:

The Ford expedition is a big, hefty vehicle.

This will surprise certain no one. The Ford expedition is a huge car. It is probably part of the factor you bought it.While a vehicle as large as the exploration is very useful for hauling people and also things, all that extra size method extra weight. The component charged with carrying all the weight is the air suspension.Weighing in at simply under 6,000 pounds, simply keeping the exploration off the ground is a significant task. Include to that a couple of people and cargo and also you space really asking a most your suspension to begin with.The OEM wait suspension in your car supports every this load by using rubber air bags attached to the struts together opposed to mechanically coils. This versatile rubber is at risk to gift punctured, torn or simply just rotting the end over time. Suppose the original suspension top top your expedition to work an excellent until there are indications of trouble. As soon as those begin, there room a lot much more on the way.

Parts that don’t last

While cars are typically constructed to last, there space several species of materials that simply don’t organize up over time.One that these species is a relocating part. Parts that relocate will rub against other surfaces or themselves. This will certainly eventually reason wear and also tear and over time, degrade the component. This is true of practically any component that moves in your car, even if it is it’s a 360-degree full variety of movement or merely just little vibrations end time.Another kind of component that is almost guaranteed to need service or instead of at some allude is an digital component.If you very own a computer or even just a smartphone girlfriend know just how quickly technology changes. The computer systems of this particular day will look like relics in 3 years. So imagine just how outdated the tiny computers in one older car must be.In addition, electronic contents have numerous tiny and also fine relations that can slip or weather and also wear under easily.The third kind of ingredient that will wear the end at some suggest is a component made of flexible materials. An example of this is the airbag.The airbags in your exploration are made of a rubber that, while durable, is at risk to dry out and also cracking. This is particularly true if friend live in one area the gets really cold or experience drastic temperature shifts.

Unfortunately, the wait suspension mechanism in your exploration features all 3 of these types of components. This nearly ensures ultimate failure.


 Air suspensions are facility and interconnected

Can you surname all the contents that comprise your exploration air suspension? If not, don’t worry. You’re not alone.Air suspensions basically job-related like this:A ride height sensor mounted at each edge takes a analysis of just how high the edge is in ~ the wheel. That then sends out that information earlier to the manage module. This module is a tiny computer the determines exactly how much air needs to it is in pushed right into the airbags.Then, it sends out a signal to a compressor come instruct it on just how much air come generate and also where to send it. Then the compressor switches on and also pushes the compressed air v pneumatic tubes right into the waiting bags. The air bags then inflate come suspend the vehicle at the proper height.It’s a long process. This cycle happens constantly while the car is in motion.All the those little components should be working together in perfect harmony for the system to role as intended. Together you can guess, the likelihood of any type of one of lock failing at some point is very, really high.Furthermore, as soon as one ingredient fails, the others will occupational harder to choose up the slack. This will certainly wear out the rest of the wait suspension components even faster.

How to deal with your exploration suspension for good

On top of all of this, probably the biggest issue with these air suspensions is cost.While replacing an airbag or even something major like the compressor could only operation a few hundred dollars, your very first repair is likely to be complied with by more. And soon. Truthfully, as soon as the repairs start with an waiting suspension, castle don’t really stop. The an outcome is a mechanism that will eventually expense you thousands come replace. ~ above a car that could not have actually all that lot time left overall, that’s not something many human being are ready to spend, leaving lock in a major bind.
