Mercedes Benz 300SEL Suspension Bellows

Detecting Problems to a Mercedes Benz 300SEL Suspension Bellow

The biggest challenge when keeping Mercedes Benz 300SEL Suspension Bellows working is making sure that there is a steady supply of air inflating the bellows. Any sign of tears and leaks should be repaired at once. For cases of an already torn bellow, this is a sign of something wrongly done with your car-as opposed to a defective product. It's as important that you are able to detect any symptoms that point to such a problem before it's too late. Read this guide to get a set of tips to help you know the things you to look out for to detect and prevent problems with Mercedes Benz 300SEL Suspension Bellows.

Uneven ride height

The car mostly stands on the suspension bellows. An uneven height when measuring and comparing the car's corners can be a sign of a leaking air spring. Unless the difference was intentional-because of suspension settings or other modifications-it's a good idea to check on the air lines, bellows themselves, pumps, and other parts to see if they are all functional.

Slow inflation

A suspension bellow that inflates at an unusually slow pace could mean a couple of things: slight tears on the bellow, leaks on the line, bad seals, poor mounts on the bead, and an overworked air pump.

Punctures on the sides

This is the most common type of suspension-bellow problem. This is usually caused by a foreign and abrasive object that rubs on the sides. Other than that, it's possible that the bellow isn't sufficiently inflated, or the wrong bellow is installed for the car.

Tears and punctures near the edges

Holes on the diaphragm or on the region near the bead plates are caused by a couple of reasons: an incorrectly installed bellow, worn-out suspension bushes, or a misaligned bump stop. Check the components of the suspension at once to avoid this kind of problem.

Detached griddle hoop

A suspension bellow with a detached griddle hoop looks very damaged and distorted. There's no hope in keeping up with this unit anymore. The main cause of getting this type of problem is user-related: inflating the bellows to its full size without enough air pressure.

  • Three Care Tips for Mercedes Benz 300SEL Suspension Bellows 04 March 2014

    It's a big challenge for a classic car like the Mercedes Benz 300SEL to ensure that all its parts and components are in working condition. This is also very true for the vital suspension bellows of its air suspension system. Fail to maintain these springs and you may find yourself driving a lowered car with a bumpy ride. This may even lead to damage to the chassis. To avoid problems like these, be guided by these three tips to maintain Mercedes Benz 300SEL Suspension Bellows.

    • Always keep clearance between parts.
    • Suspension bellows rely on a strong rubber boot filled with air to support the car. Hence, it is very important that the bellow, and the other components of the air suspension system, is free from all forms of tears and punctures. Make sure that a fully inflated air spring doesn't come into contact with other parts of the car. There shouldn't be any sharp objects nearby and/or damaging dirt that can cause tears. This should be the case for both a parked and moving car. The common culprit to a torn bellow is the air line running to it. Even the tiniest damage on these could become a major problem that calls for a complete-bellow replacement. Tinkering with the ride height greatly helps.
    • Tighten nuts and bolts.
    • Make sure all the nuts and bolts that hold the bellow in place are secure. A loose bellow may lead to excessive play and mess with the car's ride. Check the recommended specification for the Mercedes Benz 300SEL to avoid over tightening.
    • Remove everything that shouldn't be there.
    • Get rid of any hydraulic-fluid leaks, road-dirt buildup, and other stains. A good, old-fashioned cleaning with regular soap and water is the recommended agents to use. Methyl, ethyl, and isopropyl alcohol can be used as well. Any other agent-no matter how big its claim is as an ideal suspension-bellow cleaner-should not be used. Abrasives, flames, and steam cleaning are not a good idea. Rather than get rid of stains, it tends to dry the rubber and increase the risk in tearing it.
