Parts for your 1991 Nissan Primera-Steering bushes

1991 Nissan Primera steering bushes — purpose, care and when to replace

Steering bushes are absolutely relevant on the 1991 Nissan Primera (P10). The Nissan Primera P10 Factory Service Manual (Steering, ST section) describes the steering gear being mounted to the front crossmember via rubber insulators, and the Nissan FAST electronic parts catalogue (Group 48: Steering) lists these as “insulator – steering gear mounting”. In everyday terms, they’re the steering rack mounting bushes.

On this Primera, the bushes cushion the steering rack, keeping it properly located while soaking up vibration and road shock. Good bushes help the car track straight, keep on‑centre feel tight, and cut down on knocks through the column. When they’re worn, the rack can shift under load, which shows up as vague steering, clunks over bumps, tramlining, or a steering wheel that won’t settle nicely after a corner.

For servicing, it’s smart to inspect the rack bushes whenever the vehicle’s up on a hoist for a service — say every 10–20,000 kilometres or annually. Look for perished rubber, cracking, oil swelling (power steering leaks can attack rubber), or any lateral rack movement while a mate rocks the wheel left–right with the engine off. If the car’s had an impact with a kerb, add a check to the list.

• Replacement choices: OE‑style rubber keeps factory NVH, quality polyurethane can sharpen steering feel and last longer, but may add a touch more vibration.
• Basic process: support the rack, remove the rack bracket bolts, swap bushes one side at a time, refit brackets, and torque fasteners to the specs in the P10 FSM.
• Good practice: fix any power steering fluid leaks first, clean the mounts, and lightly lubricate polyurethane sleeves if supplied by the manufacturer.
• Aftercare: because the rack location can shift slightly, organise a wheel alignment check, especially front toe.

DIYers will need axle stands, a torque wrench, and access under the bonnet and car, a workshop lift makes life easier. If there’s play in inner tie rods or rack ends, address those at the same time while the rack is supported. Fresh, correctly fitted bushes restore that tidy, confidence‑inspiring steering feel the P10 is known for.

Popular questions

How do you tell if the steering bushes are worn on a 1991 Nissan Primera?

Listen and feel for a dull knock over sharp bumps, steering that feels loose off centre, or the rack shifting when someone saws the wheel while you watch from underneath. Visible cracks, squashed rubber, or bush sleeves separating from the rubber are clear signs it’s time.

Also check for power steering fluid contamination — swollen or softened rubber often points to a leak that should be fixed before new bushes go in.

Are polyurethane bushes a good idea for a P10 Primera?

They can be. Polyurethane usually tightens steering response and resists oil, making them a solid choice for spirited road use. Expect a touch more road feel through the wheel compared with OEM rubber. If comfort and factory refinement are the priority, stick with quality rubber.

Do you need a wheel alignment after replacing the steering rack bushes?

It’s wise to get the alignment checked. The rack’s position relative to the crossmember can change a fraction with new bushes, which may nudge toe settings. A quick alignment confirms everything is tracking straight and protects tyre life.
