Parts for your 2020 Mazda 3-Steering bushes

2020 Mazda 3 steering-bushes: are they actually a thing?

Short answer: no, the 2020 Mazda 3 (BP series) doesn’t use separate, serviceable “steering-bushes” in the way older hydraulic racks or some other makes do. Mazda’s own technical documentation and parts listings show the electric power steering rack is bolted to the front crossmember without separate, replaceable rack mount bushes. Technical sources: Mazda Workshop Manual (BP, 2019–, Steering System: Steering Gear and Linkage Removal/Installation, EPS Outline) and the Mazda Electronic Parts Catalog (BP series steering gear diagrams) list the rack and subframe hardware but no standalone steering-bushes service parts.

Why’s that? With an electric power steering (EPS) rack, Mazda engineers chase sharp steering feel and precise geometry. The BP rack is rigidly mounted to the subframe, and any isolation needed for noise, vibration and harshness is engineered into the rack assembly and column design rather than via big rubber bushes you can swap out. As a result, there isn’t a routine “steering-bushes” replacement on a 2020 Mazda 3, and you won’t find a genuine bush kit for the steering gear.

What owners and techs should look at instead:

• Inner and outer tie rod ends for play or torn boots
• Intermediate shaft/universal joints in the steering column for notchiness
• Front lower control arm bushes and ball joints (common sources of steering feel clunks)
• Sway bar D-bushes and links for knocks over bumps
• Front strut top mounts/bearings for creaks on steering

If there’s movement at the steering rack itself, Mazda’s workshop procedures don’t call up bush replacement, the fix is usually hardware re-torque or steering gear replacement, followed by a wheel alignment. That’s consistent with the parts catalog approach where the rack is treated as an assembly. Day-to-day, keep tyre pressures spot-on, rotate tyres regularly, and get an alignment check if the wheel doesn’t sit straight or the car drifts. Any free play, clunks on lock, or a steering wheel that doesn’t self-centre should trigger an inspection of the items above rather than a hunt for “steering-bushes.”

Sources referenced: Mazda BP Mazda 3 Workshop Manual (Steering System sections) and Mazda Electronic Parts Catalog (BP steering gear schematics), which do not list separate steering-bushes as service parts for this model.

Popular questions about 2020 Mazda 3 steering-bushes

Do 2020 Mazda 3s have steering-bushes I can replace?
Not as separate service parts. The BP series uses an EPS rack rigidly mounted to the subframe, and Mazda’s parts listings don’t show standalone steering-bushes. If you’re chasing steering knocks or play, focus on tie rods, control arm bushes, sway bar hardware, and column joints.

What’s causing a knock I feel through the wheel on my BP Mazda 3?
Common culprits are worn sway bar links, loose subframe hardware, inner tie rod wear, or strut top mounts rather than “steering-bushes.” A proper inspection on a hoist with the wheels unloaded will pinpoint the source before parts get thrown at it.

Is there any maintenance for the steering on a 2020 Mazda 3?
There’s no scheduled bush replacement. Practical care is tyre rotation and pressure checks, periodic wheel alignments, and inspection of tie rods, boots, and front-end bushes during services. Any fluid leaks from the rack would be unusual on EPS and should be investigated promptly.
