🔧 340i - Outer Tie Rod End Replacement

The outer tie rod end connects your steering rack to the front wheel knuckle. Replacing it fixes looseness, clunks, or uneven tire wear caused by a worn ball joint at the tie rod end.

Difficulty Level: Intermediate | Estimated Time: 1-2 hours (plus alignment)

---

⚠️ Safety & Precautions

• 🛑 Support the car with jack stands; never rely on a floor jack.
• 🛑 Keep hands clear when separating the joint; it can “pop” loose suddenly.
• 🛑 Do not turn the steering with the tie rod disconnected; you can damage the steering boot.
• 🛑 An alignment is required after replacement to prevent tire wear and pulling.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and remove the front wheel

• Use a 17mm socket and breaker bar to loosen the wheel bolts 1/2 turn.
• Lift the front corner with a floor jack (rated 3-ton minimum) and support with jack stands (rated 3-ton minimum).
• Remove the wheel bolts with a 17mm socket and remove the wheel.

Step 2: Mark the current position (helps keep toe close)

• Clean the exposed threads using a wire brush.
• Use a paint marker to mark the tie rod end position relative to the threads/jam nut.
• Also count and write down the number of visible threads (or measure the gap to the jam nut).
• Tip: This is not a “final alignment,” just a helper.

Step 3: Loosen the jam nut

• Spray the jam nut area with penetrating oil and wait 2-3 minutes.
• Hold the tie rod end body with an adjustable wrench.
• Use an 18mm wrench to loosen the jam nut (turn it counterclockwise) about 1-2 turns.

Step 4: Remove the tie rod end nut from the knuckle

• At the steering knuckle, remove the tie rod end nut using an 18mm socket and breaker bar.
• If a cotter pin is present on your tie rod end, remove it first using needle-nose pliers. (A cotter pin is a small safety pin that locks a nut.)

Step 5: Separate the tie rod end from the knuckle

• Install a ball joint separator tool (specialty) between the tie rod end and the knuckle.
• Tighten the tool until the joint pops free.
• Tip: Avoid hammering the knuckle to prevent damage.

Step 6: Unscrew and remove the old tie rod end

• Rotate the tie rod end off the inner tie rod by hand.
• Count the exact number of turns it takes to remove it (example: 17.5 turns). Write it down.

Step 7: Install the new tie rod end

• Thread the new tie rod end onto the inner tie rod the same number of turns you counted using your hands.
• Line up your paint marker marks as closely as possible.
• Insert the tie rod end stud into the steering knuckle.
• Install the new self-locking nut using an 18mm socket.
• Torque to 65 Nm (48 ft-lbs)

Step 8: Tighten the jam nut

• Hold the tie rod end with an adjustable wrench so it doesn’t rotate.
• Tighten the jam nut using an 18mm wrench.
• Torque to 80 Nm (59 ft-lbs)

Step 9: Reinstall the wheel

• Reinstall the wheel and hand-thread the bolts.
• Lower the car off the jack stands (rated 3-ton minimum) using the floor jack (rated 3-ton minimum).
• Tighten wheel bolts in a star pattern using a torque wrench (20-200 Nm range).
• Torque to 140 Nm (103 ft-lbs)

✅ After Repair

• Turn the steering wheel lock-to-lock while parked and confirm nothing binds or rubs.
• Road test at low speed first; confirm the steering wheel is close to centered.
• Get a professional 4-wheel alignment ASAP (do not delay) to prevent rapid tire wear.
• Recheck the jam nut area for tightness and any unusual noise after 50-100 miles.
