Nissan X-Trail T-30 2001-2007 factory workshop and repair manual download

Tools & consumables
- Floor jack + two jack stands (rated). Wheel chocks.
- 1/2" drive breaker bar, 3/8" ratchet, sockets 10–22 mm (deep sockets for nuts), extensions.
- Combination wrenches (10–22 mm). Torx/hex as required (varies by year).
- Impact wrench (optional, speeds work).
- Torque wrench (range to 200 Nm).
- Spring compressor (over‑the‑coil, two‑clamp type; heavy duty).
- Ball‑joint/tie‑rod puller or pickle fork and large hammer.
- Large pry bar, punch, cold chisel.
- Penetrating oil (PB Blaster), wire brush.
- Hammer, pliers, zip ties.
- Anti‑seize, thread locker (medium strength).
- New strut assemblies or strut cartridge + mount + dust boot/bump stop if reusing spring.
- Replacement nuts/bolts as required (some are torque‑to‑yield or corroded).
- Brake cleaner, rags, gloves, eye protection.

Safety precautions (read first)
- Work on a flat surface. Chock rear wheels. Use jack stands — never rely on the jack alone.
- Wear eye protection and gloves. Keep body clear of compressed springs.
- Use only a rated spring compressor, clamped on opposite sides of the coil. Do not use “C‑clamps” or jury‑rigged methods.
- If bolts are heavily corroded, apply penetrating oil and allow soak time; heat with an oxy/acetylene or propane torch only if safe and away from brake lines/fuel.
- Always do a front alignment after replacing struts.

Parts recommended to replace
- Front strut assembly (preferred — complete cartridge with spring and mount).
- If using core strut and replacing internals: strut cartridge, top mount/bearing, dust boot, bump stop.
- New lower strut-to‑knuckle bolts and top nuts if damaged/corroded. Sway bar link if worn.
- ABS/brake hose bracket bolts if corroded.
- Always replace mount/bearing if buying just cartridge.

Step‑by‑step procedure (front MacPherson strut, Nissan X‑Trail T30)

Preparation
1. Park, chock rear wheels, set parking brake. Loosen front wheel lug nuts slightly while car on ground.
2. Open hood, remove strut tower plastic cover(s) to expose the three top nuts (usually 3 per strut). Do not remove top nuts yet.

Raise vehicle & remove wheel
3. Loosen lug nuts fully, lift front with floor jack under jacking point, place on jack stands. Remove wheel.

Expose fasteners
4. Clean around lower strut bolts and sway bar link with brush and penetrating oil. Locate:
- Two lower bolts that secure the strut to the steering knuckle.
- Sway bar (stabilizer) end link connecting to strut.
- Brake hose/ABS sensor brackets attached to strut body or knuckle.
- Tie‑rod end at the knuckle (if necessary to separate for clearance).

Disconnect brake/ABS brackets & sway bar link
5. Unbolt brake hose/ABS brackets from the strut/knuckle. Secure hoses out of the way with zip ties — do not allow hose to carry load.
6. Remove sway bar link nut (often uses 14–17 mm). If the stud spins, hold with hex/allen/second wrench or use an impact to spin the nut off. If the link is seized, remove link from sway bar end or replace the link.

Support the knuckle / separate tie rod
7. Support the steering knuckle/constant velocity (CV) joint with a jack or wire so it won’t drop and damage the CV boot when the lower bolts are removed.
8. If tie‑rod end interferes with strut removal, separate it using a tie‑rod puller or ball‑joint separator. Use the puller to press it free; a pickle fork will damage the boot and is less preferred.

Remove lower strut bolts
9. Remove the lower strut-to-knuckle bolts (two). These are often large (14–19 mm head with 22 mm nut or similar). Use penetrating oil and breaker bar. Support the knuckle as you remove them; once removed the knuckle will hang on control arm/ball joint so ensure it’s supported.

Remove top nuts & extract strut
10. From engine bay, remove the top nuts (usually 3) holding the strut mount in the tower. Leave one partially threaded until last if you prefer to control drop. Pull the strut straight down and out through the wheel arch.
11. If the strut doesn’t drop free, check for any leftover brackets or bolts still attached.

If installing complete strut assembly (recommended)
12. Install the complete new strut assembly into the tower from the wheel arch. Feed the bottom into the knuckle. Reinstall top nuts finger tight to hold it.
13. Insert lower strut bolts into knuckle, hand tight. Reattach sway bar link and brake hose/ABS brackets.
14. With the vehicle still on jack stands and front suspension drooped to normal ride height? Important: Many manuals say tighten lower strut bolts with car at curb height or with weight on wheels. For safety, lower car to have wheels on the ground before final torqueing of certain nuts — consult manual. As a rule tighten lower bolts/nuts and sway bar links to factory torque with vehicle on ground if specified.
15. Torque all fasteners to factory spec (see manual). Common approximate ranges: top nuts 30–60 Nm; lower strut bolts 90–160 Nm; sway bar link ~40–60 Nm. Do not rely on these for final numbers — check factory values.
16. Reinstall wheel, lower car, torque wheel nuts to spec, final check.

If reusing spring and replacing cartridge/mount (requires spring compressor)
A. Compress spring while strut is off the vehicle:
- Place strut in a vise (soft jaws) or secure it vertically.
- Fit spring compressor clamps on opposite sides of the coil, about 180° apart and on the same coil turn. Use two compressors if required.
- Tighten both compressors a few turns each alternately to compress evenly. Compress until spring is loose in the strut seat and upper mount free.
- Never work over the spring while compressing. Keep hands clear.
B. Remove the center nut at the top of the strut piston (often 17 mm). Hold the piston with appropriate tool; remove nut.
C. Remove top mount, spring, dust boot, bump stop. Replace mount/bearing and dust boot. Put new mount and reassemble.
D. Reinstall compressed spring in same orientation; seat it on lower spring perch. Refit top mount and tighten center nut to spec while spring is compressed.
E. Slowly and evenly release the compressors, alternating turns, until spring seats fully. Inspect alignment of spring end on seat and that mount/bearing rotates freely.

Tool usage notes & tips
- Spring compressor: clamp on coil per instructions. Tighten each compressor equally in small increments. If using two compressors, alternate tightening both 8–10 turns at a time. Never use impact on compressor nut. Inspect clamps periodically for slippage. If compressors are not holding perfectly, stop and re‑seat.
- Ball‑joint separator / tie‑rod puller: position jaws behind tie rod stud and tighten center bolt until pop. Use puller to avoid tearing dust boot.
- Impact wrench: useful to remove corroded bolts but use breaker bar for initial torque to avoid snapping studs.
- Torque wrench: always final‑torque critical fasteners. Use correct torque direction (some nuts on strut use torque plus angle — check manual).

Common pitfalls to avoid
- Trying to remove/install strut with wheel still compressed (vehicle on stands with wheels hanging) and then torquing bolts incorrectly — some fasteners must be torqued with the car at ride height.
- Using a single‑clamp spring compressor or unsafe method — risk of spring release causing severe injury.
- Forgetting to unclip ABS/brake hoses and then putting tension on hose/connector.
- Not supporting the knuckle: dropping knuckle can tear CV boot or damage brake lines.
- Reusing a worn mount/bearing — will produce noise and poor steering return.
- Reusing corroded bolts/nuts — they can snap. Replace if rusted or if OEM specifies one‑time use.
- Failure to perform alignment after replacement — causes tire wear and poor handling.
- Over‑tightening threads without torque wrench; under‑torquing leaves parts unsafe.

Final checks
- Double‑check all fasteners, brake lines clear and secure, sway bar link reinstalled.
- Reinstall wheel, lower vehicle, torque lugs to spec.
- Road test gently, listen for noises, check steering feel. Get a 4‑wheel alignment immediately.

That’s the procedure. Follow factory torque specs and repair manual details for your model year. Replace mount/bearing and use complete struts if possible to avoid spring‑compressor work.
