Do I need to replace all four shocks?
Not automatically. Conventional shocks and struts are normally replaced in pairs across the affected axle to keep damping balanced. The other axle is assessed separately. Air springs and complete air struts need their own vehicle-specific assessment rather than a blanket four-corner replacement.
Can a leaking air spring be repaired?
A leak at a connection or serviceable line may be corrected without replacing the air spring. A damaged rubber bellows usually needs a suitable replacement spring or assembly. The leak location, damper condition and available parts determine the work.
Why does my car sink overnight but rise when started?
The compressor may restore height after air has escaped while the vehicle was parked. Air springs, connections or valve operation need assessment. Record which corner drops and how long it takes. Being able to rise again does not mean the underlying fault has disappeared.
How long does suspension repair take?
A straightforward conventional component replacement may fit within one working day when parts are available. Multiple worn items, seized fasteners, air-loss testing and ordered parts can take longer. Mechanics confirms the expected collection time after assessing the job and parts availability.
Will wheel alignment fix the knocking?
Alignment adjusts wheel angles. It does not repair a loose joint, worn mount or damaged component. The noise needs inspection first. Geometry should then be checked when required by the repair, rather than using alignment as a substitute for mechanical work.
What should a suspension quote include?
Check the component, quantity, parts manufacturer, labour and VAT. Ask whether top mounts, bearings, hardware, alignment and any ride-height calibration are included. A per-unit price and an axle-pair price are not the same offer. The planning figures above are estimates, not a fixed Mechanics price list.
Is suspension repair covered by a warranty?
Coverage depends on the selected parts and repair. Any offered warranty should identify the covered component, parts and labour terms, duration or mileage limit, and exclusions for wear or damage. Alignment, an air spring and a replacement compressor need their own scope. Keep the applicable written terms with the invoice so a later concern can be assessed against the agreed work.
