Parts for your 2017 Subaru Legacy-Tie rod end

2017 Subaru Legacy tie-rod end — what it does and when to replace it

Based on technical references — including the Subaru Factory Service Manual for the 2015–2019 Legacy/Outback (BN/BS) steering section and Subaru’s genuine parts catalogue for MY2017 — the 2017 Subaru Legacy is fitted with inner and outer tie-rod ends as part of its rack-and-pinion steering. That makes the tie-rod end a relevant, serviceable component on this model.

On the 2017 Legacy, the outer tie-rod end connects the steering rack to the steering knuckle. It’s a compact ball-and-socket joint that lets the wheel pivot smoothly while holding toe alignment steady. When it’s in good nick, steering feels direct and the tyres wear evenly. When it wears, the car can start to wander, the steering wheel may shimmy, and tyres can scrub out on the edges.

As part of regular servicing, the tie-rod ends should be visually inspected for torn dust boots, grease seepage, corrosion, and any play. Given Aussie and Kiwi roads, kerb strikes, potholes and corrugations can accelerate wear, so checks at each scheduled service interval are a smart move. If any looseness is found at the joint or at the inner tie rod, replacement is the safe call.

• Common symptoms of a crook tie-rod end:
  • Clunking over bumps or when turning at low speed
  • Loose or vague steering feel, tramlining or wander
  • Uneven or rapid tyre wear on the inner/outer edges
  • Split boot or visible rust around the ball stud

When replacing, it’s best practice to match quality parts to the BN-chassis Legacy and verify left/right fit as required. Mark the old tie-rod’s position or count turns to get the new one close, but always organise a professional four-wheel alignment afterwards — toe must be set accurately to protect tyres and restore proper handling. Torque fasteners to the factory spec and ensure the rack boot isn’t twisted or pinched on reassembly.

Owners who regularly commute on rough surfaces or who’ve had a solid kerb knock should have the steering linkage checked promptly. Tie-rod ends are safety-critical, leaving one worn too long can lead to poor steering control and expensive tyre replacement.

Popular questions about 2017 Subaru Legacy tie-rod ends

How long do tie-rod ends last on a 2017 Legacy?
With normal use, many will see well over 80,000–120,000 kilometres, but life varies with road conditions and driving style. Regular inspections catch issues early, especially after pothole hits or off-bitumen driving.

Do I need a wheel alignment after replacing a tie-rod end?
Yes. Even if the new end is set close by counting turns, the toe setting will shift. A proper alignment protects tyres, keeps the steering wheel centred and ensures the Legacy tracks straight.

What are the signs mine need attention?
Look for uneven tyre wear, a wandering feel at motorway speeds, clunks on tight turns or a split dust boot with grease weeping out. Any play felt at the outer joint during a steering shake-down is a red flag.
