Parts for your 2018 Nissan Pathfinder-Steering bushes

2018 Nissan Pathfinder steering bushes — what they do and when to replace them

Yes, the 2018 Nissan Pathfinder (R52) does use steering bushes. Factory technical references including the Nissan Electronic Service Manual (ESM) for the R52 platform (Steering – ST section) and the Nissan Electronic Parts Catalogue (EPC/FAST) steering gear and linkage diagrams show a rack-and-pinion mounted to the front crossmember using rubber mounting insulators/bushes. On many Pathfinders these bushes are supplied as part of the steering rack assembly, though some markets and aftermarket suppliers list them separately.

On this model, steering bushes sit between the steering rack housing and the subframe. Their job is to isolate vibration, keep the rack firmly located under load, and help the wheel feel stay tight and consistent. When they age, harden, or tear, the rack can shift slightly, which can translate into a dull clunk on turn-in or over bumps, vague on-centre feel, and a bit of wander at highway speeds.

As part of routine servicing, it’s smart to have the steering bushes visually checked whenever the front end is on a hoist—say every 20,000 km or during tyre rotations. Look for cracking, flattening, or oil swelling. The R52 typically runs a hydraulic power steering rack, if there’s a fluid leak, the rubber can deteriorate faster, so any seepage should be sorted promptly.

• Common signs they’re tired: knocking over potholes, imprecise steering, a thud when shifting from reverse to drive, or visible rack movement while someone rocks the steering wheel.
• Simple driveway check: with the engine off and the wheels on the ground, have a helper nudge the wheel left–right while watching the rack—any perceptible shift at the mounts points to worn bushes.

Replacement approach depends on parts availability. Nissan often supplies the bushes integrated with the rack, in that case, a complete rack swap is the OE path. Where separate bushes are available, they can be pressed in with the rack in or out of the vehicle, depending on access and tooling. After any bush or rack work, a four-wheel alignment is a must, and all mounting bolts should be torqued to the ESM spec. While you’re there, check inner and outer tie rods and front control arm bushes, as wear in those can mimic steering bush symptoms.

To keep them sweet longer, avoid contaminating the bushes with oils and solvents, and don’t ignore tyre cupping or uneven wear—those are early hints that something in the front end, possibly the steering bushes, needs attention.

• Popular questions

Do 2018 Pathfinder steering rack bushes sell separately, or only with the rack?
From the factory, many R52 Pathfinders treat the rack mounting bushes as part of the steering gear assembly. However, some aftermarket suppliers and certain markets list separate replacement bushes. It’s worth checking by VIN with a parts specialist—if separate bushes aren’t available, a complete rack may be the OE route.

What symptoms point to worn steering bushes versus control arm bushes?
Worn steering bushes often cause a knock on initial steering input and a loose, wandering feel, with visible rack movement at the mounts. Control arm bushes more commonly cause braking shimmy, tyre feathering, and clunks mainly over bumps rather than on steering input. A proper inspection on a hoist will tell them apart quickly.

Do I need a wheel alignment after replacing steering bushes?
Yes. Any time the steering rack or its mounting is disturbed, a wheel alignment should be carried out. It brings the steering wheel back to straight-ahead and ensures correct toe, which protects tyre life and restores crisp steering feel.
