The L320 and L322's air spring bellows split with age and Ontario winters, and the Wabco compressor burns itself out trying to compensate. We replace the failed struts and the compressor together, in your driveway, and recalibrate the ride height on site.
These Range Rovers ride on rubber air bellows at each corner, fed by a single Wabco compressor. The bellows fold and unfold with every bump, and after years of that — accelerated by road salt, grit trapped in the folds, and deep cold that stiffens the rubber — they crack and split. A splitting bellows leaks air constantly, the truck settles overnight, and the corner that's lost its spring sits visibly slumped by morning.
The compressor pays the price. It was engineered to top the system up occasionally, not to fight a permanent leak, so it runs longer and hotter every day until the piston seal wears out and it can't build lifting pressure at all. That's when the dash declares "Air Suspension Inactive" and the truck parks itself at bump-stop height. By the time the compressor dies, the leak that killed it is still there too — which is why the honest fix is both together.
On the L320 and L322 the front struts are the usual offenders, and they age as a pair: when one side's bellows splits, its twin has the same years and the same kilometres on the same rubber. Replacing fronts in pairs with a new compressor, then recalibrating heights electronically, puts the system back to genuinely reliable — these trucks ride beautifully on air when the air system is healthy.
If your Land Rover is doing any of these, this is the likely cause:
Driving on a slumped corner hammers the bump stops through every pothole and loads the chassis in ways it wasn't designed for — and a compressor running flat-out against a leak is consuming its remaining life by the day. The real cost of waiting is scope creep: one split bellows becomes two struts plus a dead compressor plus a saturated air drier. There's also the practical problem that a fully failed system can leave the truck too low to drive at all, on its belly in your own driveway. Fix it while it's one corner's problem.
That's exactly the situation mobile repair exists for. The truck doesn't need to move — we work on it where it sits, replace the struts and compressor, recalibrate, and you drive it out of the driveway at proper height. No flatbed required.
The struts and the Wabco compressor are genuinely costly parts, and dealer labour on top pushes quotes into the $4,500–$6,500 range. We give you one flat price for the complete job — parts, labour, and calibration — before any work starts, so the number you approve is the number you pay.
We test rather than assume. If the compressor still builds full pressure in a reasonable time, it stays — and we'll tell you so. But a compressor that's spent months running against a leak usually shows measurable wear, and pairing a tired compressor with new struts is a comeback waiting to happen. The test results make the call, not a sales pitch.
We don't recommend it on these trucks. Coil kits compromise the ride quality and load-levelling these vehicles are built around, often leave permanent warnings on the dash, and knock down resale value. A properly repaired air system — good bellows, healthy compressor, no leaks — is reliable for many years.
