Ramp Inspection and Play Testing
Each joint, bush and link is loaded with a bar with the wheels off the ground. It is the only way to separate a worn bush from a worn ball joint, and it is what stops a knock turning into a list of parts.
A great many of these cars ride on air or on hydraulics rather than on steel, which makes the diagnosis a system test rather than a look at four corners. Al Zaabi Autocare carries out Brabus suspension and shock absorber repair in Mussafah, Abu Dhabi, across the Brabus-built G-Class, S-Class, GLE and GLS cars.

Suspension is measured before it is quoted. A knock has several possible sources and only one of them is yours, so everything is checked on the ramp against the other side of the car.
Open the full list below for everything a Brabus suspension repair covers, and what each part of it involves.
Each joint, bush and link is loaded with a bar with the wheels off the ground. It is the only way to separate a worn bush from a worn ball joint, and it is what stops a knock turning into a list of parts.
Dampers are checked for leaks, for bump stop damage and for how the car settles after being pushed down. Heat kills damper oil quietly, and a tired damper ruins tyres long before it fails outright.
Broken springs are more common here than owners expect, and a car sitting low on one corner with a knock over bumps is usually a spring rather than a damper.
Collapsed top mounts and seized top bearings read as heavy steering at parking speed and a creak on lock. Both are replaced with the strut rather than after it.
Control arm bushes perish in this heat and take the geometry with them. They are replaced in axle pairs so the car sits, steers and wears its tyres evenly.
The cheapest parts on the car and the loudest. A worn drop link is a rattle over rough surfaces, and left alone it wears the anti-roll bar bush it works against.
Bar bushes dry out and clonk. The bar, its mounts and its links are treated as one assembly because replacing one of the three rarely ends the noise.
Where the car rides on air, the compressor, dryer, valve block, height sensors and springs are tested as a system and the fault found before anything is replaced.
Electronically controlled dampers are read for circuit faults and commanded through their range, so a control fault is not treated as a worn damper or the other way round.
Every suspension job finishes on the alignment rack at the car's specified ride height. New parts move the geometry, and leaving it is how a repair turns into a set of tyres.
Suspension wears in a predictable order on any given car. Knowing the order is what stops a knock turning into a list of parts.
Air struts perish at the folds and the valve block stops sealing. A car that sits down overnight on one corner is one of those two, and testing says which before anything is replaced.
The hydraulic system on the larger coupes and saloons leaks at the struts and the pulsation dampers, and it runs at pressures that make guesswork unwise. It is tested properly and repaired by component.
An air compressor working around a leak runs hot and dies. Replacing it without finding the leak buys a few months and another compressor.
Bushes and ball joints in the front lower arms wear and take the steering feel with them. They are replaced in pairs and the car is aligned afterwards.
The self-levelling rear on the estate cars has its own accumulators and struts, and a sagging back end is usually those rather than springs.
Inspect, quote, replace in pairs, align, road test.
The car goes up and every joint is loaded and compared with the other side. You are shown what moves and what does not.
What is worn, what is worth doing now and what can safely wait, priced before anything is ordered.
Parts replaced in axle pairs where the job calls for it, to the manufacturer's torque figures, with bushes pressed rather than forced.
Four-wheel alignment at the correct ride height, then a road test over the surfaces that showed the fault in the first place.
What you drive away with after a Brabus suspension repair, beyond the invoice.
The knock over expansion joints and the creak on lock are gone, which on most cars is the whole reason the owner booked it in.
A car that holds its line instead of wandering, and a wheel that sits straight when the car does.
Worn suspension eats tyres from the shoulder inwards. Fixing it and aligning it is usually cheaper than the tyres it saves.
A damper that cannot control the wheel lets it skip under braking. Brakes get the credit for stopping the car, but the suspension decides whether they can.
Not an extra line on the bill. If the work moved the geometry, setting it back is part of the work.
You are told which joint was worn and shown the movement, rather than sold the whole corner because something in it knocked.
Find yours below. If it is not listed it is still covered, so call the workshop and ask.
Suspension rarely fails all at once. It degrades until the car feels normal to you and wrong to everybody else.
The most common complaint and usually the cheapest: a drop link, a bush or a top mount. It stays cheap only while it is still a noise.
One corner down overnight is a broken spring or an air system losing pressure. The whole car down is the air system or worn springs all round.
A shoulder worn away on one edge is the suspension telling you about itself in the only way it can. Read it before you buy tyres.
The car needs constant small corrections to hold a lane. Usually bushes, a ball joint or geometry that has moved.
More than one rebound after a dip means the damper is no longer controlling the spring, whatever it looks like from outside.
Oil down the body of a shock absorber means it has lost its seal, and once it has, it is not damping anything.
On adaptive or air-sprung cars this is a stored fault with a circuit attached to it, and it is readable rather than a mystery.
An air compressor that runs for a long time or runs often is working around a leak, and running it that way is what kills it.

What Brabus owners ask before booking a suspension repair in. If yours is not here, call the workshop and ask.
An air strut leaking, a valve block not sealing, or a compressor that can no longer keep up. All three do the same thing to the car and cost very differently, so the system is pressure tested corner by corner first.
Usually yes, because the parts are available individually. Replacing one leaking strut and servicing the compressor is a great deal cheaper than converting the car to coils, and it keeps the ride the car was designed around.
Yes. A new damper on one side and a tired one on the other makes the car brake and corner unevenly, which is worse than two matched but worn ones. Bushes, links and joints are replaced where they are worn, side by side.
Four-wheel alignment is part of the job wherever the work moves the geometry, which is almost every suspension repair. It is done at the car's specified ride height, not at whatever height it happens to be sitting.
Less than the service schedule assumes. Heat hardens rubber and the road surface loads it, so bushes, top mounts and links wear faster here than the figures written for cooler countries.
Both. Compressors, dryers, valve blocks, height sensors and lines are repaired or replaced individually once the system has been tested. Replacing the whole system because one corner drops is how people overpay.
