Parts for your 2019 Nissan Serena-Steering bushes

2019 Nissan Serena steering bushes: what they do and when to replace

Based on Nissan’s Electronic Service Manual (ESM) for the C27 platform (Steering – ST section) and Nissan FAST parts catalogue references that list the steering gear “insulator” mounts, the 2019 Nissan Serena uses a rack-and-pinion electric power steering (EPS) assembly secured to the front subframe via rubber bushes. So yes—steering bushes are fitted and relevant on this model.

On the Serena, the steering bushes (often called rack insulators) cushion the steering rack, keeping it located while soaking up vibration and road shock. They’re small bits of rubber doing a big job—damping noise, maintaining rack alignment and helping deliver that tidy on-centre feel families expect from a people mover. With EPS there’s no hydraulic fluid, but the bushes still cop loads from potholes, kerbs, towing and fully laden road trips.

Over time, rubber hardens, cracks or compresses. When that happens, drivers may notice a dull clunk over bumps, a vague or twitchy feel around centre, shimmy under braking, or the wheel needing a little constant correction. Tyres can show feathering and alignments don’t seem to “hold” as long. A tech can spot movement by carefully prying the rack at its mounts or seeing perished rubber.

For servicing, a visual check every 10,000–20,000 km (or annually) is a good shout, especially if the Serena lives on rough chip or carries seven seats full of mates most weekends. If replacement’s due, quality OEM-style rubber bushes keep NVH in check, stiffer polyurethane can sharpen response but may add road feel and hum—choose based on the owner’s priorities. Follow the ESM torque specs, support the subframe properly and nip everything up at normal ride height so the rubber isn’t preloaded. If Nissan specifies new one-time-use bolts or nuts, fit them. An alignment afterwards is recommended, as subframe or rack fastener loosening can nudge toe.

Handy tips:

• Keep oils and solvents off the bushes, petroleum can attack rubber.
• If there’s a knock only when cold, the rubber may be hardened—inspect sooner rather than later.
• With EPS, there’s no fluid to top up, but do check column joints and tie-rod ends while you’re under there.

FAQs

Do 2019 Nissan Serena models use replaceable steering rack bushes or is the rack replaced as a unit?

The C27 Serena’s rack is mounted with separate rubber insulators (bushes) that can be replaced without changing the entire rack. Nissan parts listings call them steering gear insulators, and they’re serviced individually. The rack itself is only replaced if there’s internal wear, play or EPS faults.

What are the tell-tale signs the Serena’s steering bushes are worn?

Common clues include a dull clunk over sharp bumps, vague on-centre feel, tramlining on coarse roads, and alignments that don’t seem to last. A mechanic may notice visible cracking or deformation of the bush rubber and slight rack movement against the subframe when levering.

How much does steering bush replacement typically cost in Australia or New Zealand?

As a ballpark, parts usually land around AUD/NZD $60–$220 depending on brand. Labour can run 1.5–3.0 hours based on workshop approach and corrosion, plus a wheel alignment (often $90–$140). All up, many owners see totals in the $300–$650 range. Actual pricing varies by region and parts choice.
