Audi A5 Quattro Stabilizer Bar Bushing Kits

Audi A5 Quattro Stabilizer bar bushing kits

Starting at $27.95, AutoBuffy stocks 9 stabilizer bar bushing kits from Delphi, Mevotech Supreme, and MOOG for the Audi A5 Quattro. These rubber or polyurethane sleeves clamp the sway bar to the subframe, controlling body roll in corners. When they wear out, the bar shifts and knocks, handling becomes vague, and uneven tire wear follows.

Signs your Audi A5 Quattro needs new stabilizer bar bushing kits

  • Clunking or knocking noise from the front or rear suspension over bumps, dips, or rough pavement
  • Rhythmic thumping that changes with vehicle speed or road surface texture
  • Noticeable body lean or excessive roll when cornering at moderate speeds
  • Steering feels loose or imprecise, especially during lane changes
  • Vibration felt through the floorboard or steering wheel at low speeds over rough roads
  • Visible cracking, splitting, or flattening of the rubber bushing when inspected under the vehicle

Which stabilizer bar bushing kit should you buy for your Audi A5 Quattro?

The two main decisions are material — rubber versus polyurethane — and whether you need front, rear, or both positions. OE-spec rubber kits restore factory feel and noise isolation, while polyurethane kits firm up handling at the cost of slightly more NVH. Make sure the inner diameter matches your Audi A5 Quattro's sway bar diameter exactly, as even a few millimeters of mismatch causes premature wear or persistent noise.

Replacing stabilizer bar bushing kits on a Audi A5 Quattro

Easy⏱ 30–90 minutesFloor jack and jack stands or a vehicle liftSocket set and ratchetCombination wrench setBushing grease (lithium or PTFE-based)Wire brush or sandpaper for cleaning the sway bar

With the Audi A5 Quattro safely raised and supported, remove the bushing bracket bolts, slide the old bushings off the sway bar, and clean the bar surface before installing the new bushings. Polyurethane bushings should be greased before the brackets are torqued down. Snug the bracket bolts with the suspension at ride height to prevent binding, following the service manual's fastener sequence for the Audi A5 Quattro.

Frequently asked questions

How much does it cost to replace stabilizer bar bushing kits on a Audi A5 Quattro?
Parts start at $27.95 for the Audi A5 Quattro. A complete DIY job costs only the parts plus a tube of bushing grease. Shop labor typically adds one to two hours of labor time. Replacing bushings at the same time as end links saves a second lift appointment and is generally recommended when either component shows wear.
How long do stabilizer bar bushings last on a Audi A5 Quattro?
Rubber bushings on the Audi A5 Quattro commonly last several years under normal driving but degrade faster in extreme climates, on rough roads, or when exposed to oil or brake fluid leaks. Polyurethane bushings generally outlast rubber by a significant margin. Inspect them any time the vehicle is on a lift for other suspension work.
Can I drive my Audi A5 Quattro with worn stabilizer bar bushings?
Worn bushings on the Audi A5 Quattro rarely cause immediate safety failure, but they allow the sway bar to shift under load, reducing cornering stability and predictability. Continued driving with severely deteriorated bushings can accelerate wear on the sway bar itself and end links. Replacing them promptly is low-cost insurance against more expensive damage.
Do I need to replace the sway bar end links at the same time on my Audi A5 Quattro?
Not always, but it is strongly recommended. End links and bushings wear at similar rates on the Audi A5 Quattro, and a failed end link produces the same clunking symptoms. If the end links show any play, torn boots, or corrosion, replacing both components together eliminates the noise completely and avoids a repeat repair in the near future.
Do polyurethane stabilizer bar bushings require grease on the Audi A5 Quattro?
Yes. Unlike rubber bushings, polyurethane bushings on the Audi A5 Quattro require a coating of the included or separately purchased lithium- or PTFE-based grease at installation. Skipping this step causes squeaking as the bushing rotates slightly against the bar. Re-greasing may be needed at long service intervals to maintain a quiet, rattle-free installation.
How do I know if the noise on my Audi A5 Quattro is the bushings and not the end links?
With the Audi A5 Quattro safely on a lift, grab the sway bar and attempt to move it up, down, and side to side. Clunking with lateral movement typically points to worn frame bushings. Clunking with up-and-down movement at the bar's ends usually indicates failed end links. Both tests together quickly isolate which component is the source.
