A conversion kit swaps air springs, compressor, and electronics for steel coils and shocks, permanently. It's the right move on an old, paid-off vehicle with a repeat failure — often once two-corner repairs already run 40-60% of the kit's cost — and the wrong move on a newer luxury vehicle or a truck that actually uses air for load-leveling.
A failing air suspension compressor sags overnight, runs nonstop trying to keep up, then quits — parts run $29.95 to $553.95, and a saturated $15-80 dryer is usually what killed it in the first place.
A single air spring or strut runs $150-$1,370 installed per corner, and a full four-corner luxury SUV job can hit $4,800. Here's the real per-component, per-vehicle breakdown, plus how to avoid paying for parts you don't need.
Air suspension trades steel coil springs for air-filled springs and a compressor so the vehicle can self-level under load — and it fails one of three ways: a leaking spring, a dead compressor, or a bad solenoid. Here's how the six-part system works and what to do when it doesn't.
Carrier bearing replacement runs $250-$600 at an independent shop in 2026, but the part itself can cost as little as $3. Full cost tables by scenario and vehicle type, plus how to tell when a $1,500 driveshaft quote is legit and when it's lazy.
A carrier bearing and a center support bearing are the same part: the rubber-cushioned bearing holding up the middle of a two-piece driveshaft. Most last 100,000+ miles, and replacement runs $250-$600 at a shop or as little as $5 in parts if you DIY.
