Parts for your 2014 Subaru Legacy-Tie rod end

2014 Subaru Legacy tie-rod end — what it does and when to replace it

The 2014 Subaru Legacy (BM/BR) absolutely uses tie-rod ends. Subaru’s Factory Service Manual for the 2014 Legacy includes dedicated procedures for “Tie-rod – Outer” removal/installation within the Steering/Rack-and-Pinion section, and the Subaru Electronic Parts Catalogue lists outer tie-rod end assemblies and inner tie-rods for this model. Mainstream workshop guides covering 2010–2014 Legacy/Outback also describe inspection and replacement of these parts, confirming they’re standard equipment.

On this Legacy, the tie-rod end links the steering rack to the front steering knuckle. It’s the last joint in the chain that turns the wheels when the driver moves the steering wheel. It pivots on a ball-and-socket joint to cope with suspension travel and steering angle while keeping the front wheels pointed where they should be. When a tie-rod end wears, toe setting goes out of whack, the steering can feel vague, and tyres can scrub out faster than a long weekend road trip.

Servicing the tie-rod ends on a 2014 Legacy starts with regular checks at routine services (every 10,000–15,000 km). Because the OEM parts are sealed units, there’s no greasing to do, instead, look and feel for play, torn dust boots, and corrosion. If there’s any looseness at the ball joint, or if the boot is split and has let grit in, it’s time to replace.

• Common signs it’s due: clunks over bumps, steering wander, a shimmy at speed, uneven or rapid tyre wear, and a “dead” spot on-centre.
• Visual clues: cracked or missing dust boots, rust stains around the joint, or grease leakage.
• Workshop check: with the front raised safely, grasp the tyre at 3 and 9 o’clock and feel for play while watching the joint.

Replacement is straightforward with the right tools: crack the lock nut, split the joint at the knuckle with a puller, spin the old end off, then thread the new one on to the same length or turns as a baseline. Use the correct castle nut and new split pin, and torque to the Subaru spec from the service manual. Counted threads will get it close, but a precision four-wheel alignment is non-negotiable straight after—this protects tyres and restores crisp steering.

Good practice is to inspect both sides and the inner tie-rods while you’re there. If one outer is badly worn, the other may not be far behind. Avoid striking the housing with a hammer, keep the ball-joint stud clean, and never twist the rack—support it properly. Done right, quality replacements will go the distance across plenty of Kiwi and Aussie kilometres.

Popular questions

How can someone tell if a 2014 Legacy’s tie-rod end is worn?

They’ll usually notice a looseness in the steering, a knock over rough roads, or uneven tyre wear. A quick check with the car safely raised—gripping the tyre at 3 and 9 o’clock and feeling for side play while watching the joint—often reveals movement at the tie-rod end. Torn dust boots or rust-stained grease are also giveaways.

Is a wheel alignment needed after replacing a tie-rod end?

Yes. Even if the new end is fitted to the same number of turns, the toe setting won’t be perfect. A proper alignment right after the job prevents premature tyre wear and keeps the Legacy tracking straight.

Should both tie-rod ends be replaced at the same time?

Not mandatory, but it’s often sensible. If one end has worn out from age or kilometres, the other side may be close behind. Replacing them as a pair can save a second alignment and keeps steering feel consistent left to right.
