Theory — what the stabilizer (sway) bar does (simple analogy)
- The stabilizer bar is like a seesaw arm that ties the left and right suspension together. When one wheel moves up and the other stays lower (body roll in a turn), the bar twists and resists that motion, reducing lean and keeping tires more evenly loaded.
- It’s not holding the car up; it resists roll. The bar’s stiffness (diameter, material, lever length) controls how much roll is resisted.
- Rubber or polyurethane bushings and end links connect the bar to the chassis and control arms. Bushings isolate vibration and allow controlled rotation; end links transfer motion from control arm to bar.

Why you repair it
- Worn bushings or linkage lets the bar move improperly (clunking, rattles), reduces anti‑roll effectiveness (more body roll), or causes uneven handling.
- Damaged components can fail entirely, causing sudden handling changes — a safety issue.

Detailed components (every common part you’ll meet)
- Sway (stabilizer) bar: a one‑piece bent steel tube connecting left and right. May be hollow. Mounts under the subframe or body.
- Bushings (frame mounts): rubber or polyurethane sleeves that cradle the bar at two or more points on the chassis. Often split for installation.
- Brackets (bushing brackets): steel clamps bolted to the chassis that hold the bushings in place.
- End links (drop links): connect the bar ends to lower control arms or knuckles. Types:
- Ball‑joint style (with sealed ball joints) that pivot freely.
- Rigid links with bushings at each end.
- Bolts, nuts, washers: fasteners for brackets and links; often torque‑to‑spec.
- Sleeves: metal tubes that go through the bushing inner diameter (not in every bushing type).
- Grease/anti‑seize: used on sleeves or bolts (only where recommended — do not use petroleum grease on some bushings).
- Mounting points on chassis/subframe and control arm links.

Symptoms and basic diagnosis (what you’ll see/hear)
- Clunking/noise over bumps — classic sign of loose/worn end links or bad bushings.
- Excessive body roll in turns — reduced anti‑roll effect.
- Loose or sloppy feel through steering, wandering.
- Visual: cracked, split, flattened, or missing bushing rubber; rusted/broken end links; sway bar rubbing/metal‑to‑metal.
- Quick tests:
- With car safely supported on jack stands, try to move the sway bar by hand at the end and at mounts. Excessive play or metal contact indicates wear.
- Bounce each corner and listen for clunks; have an assistant watch link movement.

Tools & supplies
- Jack and quality jack stands (use stands; never rely on jack only)
- Wheel chocks, gloves, eye protection
- Socket set and ratchet (commonly 10–19 mm for Nissan; have metric)
- Combination wrenches
- Torque wrench
- Penetrating oil (PB Blaster / Kroil)
- Pry bar or large screwdriver
- Hammer and punch (for stubborn sleeves)
- Wire brush and brake cleaner
- New bushings and/or end links (OEM or quality aftermarket)
- Anti‑seize or light grease (silicone or lithium where appropriate) — read bushing maker’s recommendations
- Locking pliers or hex key to hold stud while turning nut (if needed)
- Replacement bolts/nuts if hardware is corroded (grade and length matched)
- (Optional) Impact wrench, heat source (propane torch) — use cautiously

Preparation and safety
- Work on level ground. Chock rear wheels. Set parking brake.
- Loosen wheel lug nuts slightly, lift car, remove wheel to access sway bar and links.
- Support car on correctly rated jack stands on pinch welds or lift points.
- Allow parts to cool if hot; use eye protection and gloves.
- Have replacement parts on hand and service manual or a reliable torque spec reference for the R32 model. If you can’t find exact torque, typical ranges: bracket bolts ~30–50 Nm, end link nuts ~40–80 Nm — but always verify.

Step‑by‑step — replacing bushings and/or end links (front procedure; rear is similar but orientation differs)
1. Access:
- Remove wheel. Locate stabilizer bar, bushings, and end links.
2. Inspect and prep:
- Spray penetrating oil on end link nuts and bracket bolts. Let soak 10–20 minutes.
- Understar: note bar orientation and bushing placement; take photos for reference.
3. Remove end link nuts:
- Hold the stud so the stud doesn’t spin (use an Allen key into the stud, hold with pliers, or hold hex on studs). Remove top and bottom nuts as applicable. If stud spins, lock the inner hex or hold ball joint with pliers.
- If sealed ball joint end link is corroded, you may need to remove the entire link with the control arm bolt.
- If nuts are frozen, apply more penetrating oil, use heat carefully, or cut/replace bolt.
4. Support the bar:
- Before removing bracket bolts, support the bar so it doesn’t fall suddenly. Use a jack or a block.
5. Remove the bushing bracket bolts:
- Unbolt the two bracket bolts (one per bracket). Keep bolts if in good shape; usually replace if rusty.
6. Remove old bushings:
- Pull the bar down and slide out the bushings. Split bushings peel off; solid types may need prying.
- Clean the bar where bushings sit. Remove rust, dirt, and old grease with wire brush and cleaner.
7. Clean mounting area:
- Clean bracket mating surface on chassis and inside bracket. Ensure no high spots or rust interfering.
8. Fit new bushings:
- If split type, orient split away from bracket load path (usually top or inner side as recommended).
- If bushings have a grease channel or require lubrication, apply lubricant recommended by bushing maker (many poly bushings come pre‑lubed with synthetic grease; rubber bushings often dry).
- Insert metal sleeve if supplied.
9. Reinstall bracket and torque:
- Lift bar into position, place bushings, loosely install bracket bolts.
- Do not fully torque until the car is on the ground — for many bushings, manufacturer recommends torquing with normal ride height so bushings aren’t preloaded in a twisted position. If manual says torque with vehicle on ground, follow that. If you must torque now, use correct torque spec.
10. Install end links:
- Reattach end links to control arm and bar. On many R32s, the end link stud goes into bar eye and nut tightens to a specified torque. Make sure the link is straight and not binding.
- If replacing end links, fit new hardware and tighten to spec.
11. Reinstall wheels, torque lugs properly, lower car.
12. Final torque:
- With car at resting ride height on ground, torque bushing bracket bolts and end link nuts to spec per manual.
13. Test:
- Bounce the car, check for noises and correct operation. Road test at low speed, then recheck all fasteners after 50–100 km.

Notes for rear sway bar (differences)
- The rear bar mounts to the subframe or body at different points; orientation of bushings and links may differ.
- Some R32s have adjustable end links or offset bars — mark orientation and settings before removal if you have aftermarket hardware.

Common problems and troubleshooting (what can go wrong)
- Seized or broken bolts: corrosion can lock bolts. Use penetrating oil, heat, or cut them out and replace with new bolts of correct grade.
- Spun studs: end link studs can spin in ball joints. Hold stud with hex or use two wrenches.
- Overtightening bushings while car is on jack stands: this can preload and distort rubber or poly bushings, causing noise and premature wear. Torque to spec with vehicle on ground if the manual says so.
- Using wrong lubricant: petroleum‑based grease can degrade some rubber bushings. Use silicone or manufacturer-recommended grease.
- Incorrect bushing orientation: can cause squeaks or binding. Split line orientation matters in some designs.
- End link replacement with wrong length: can pre‑load or under‑load the bar, causing poor handling or noise.
- Polyurethane bushings without proper lubrication: squeak until greased; follow instructions.

Safety and repair pitfalls
- Never work under a car supported only by a jack. Use jack stands.
- If you must use heat to free bolts, protect nearby components (fuel lines, rubber hoses).
- Replace corroded hardware—don’t reuse bolts that are visibly compromised.
- After removing one side, support the bar so it doesn’t spring and damage threads/brackets.
- If you’re unsure of torque specs, get a factory manual or online PDF for the Skyline R32 — exact torques vary by model and year.

Signs the repair worked
- No more clunks over bumps.
- Reduced body roll / improved steering feel.
- Visual: new bushings in place, end links snug, no metal‑to‑metal contact.
- Re‑check fasteners after first short drive and again after ~100 km.

Maintenance tips
- Inspect bushings and links every 20–30k km or when handling changes.
- Keep bracket mounting surface clean and lightly lubricated if using poly bushings.
- Replace end links in pairs (both sides) for symmetric handling.

Final words (concise)
- The job is straightforward for a beginner with basic tools, but rusted fasteners and correct torque/installation orientation are common stumbling blocks. Take photos before you start, use penetrating oil, support the car safely, and follow torque and lube recommendations. If uncertain about torque specs for the R32, consult an R32 factory service manual or reputable online resource and use those exact numbers.
