Nissan Primera P12 (2001–2007) is a legendary sedan that has gained popularity due to its reliability and balanced characteristics. However, even this model has “weak points”, one of which is drive mechanisms. Not only ride comfort, but also safety depends on the condition of the drive: worn CV joints or axle shafts can lead to loss of control at speed.

In this article we will analyze all types of drives on Primera P12 (front, rear for all-wheel drive versions 4WD), typical faults and their symptoms, and we will also give step-by-step instructions for diagnosis and repair. We will pay special attention to the selection of spare parts - original and analogues - and the nuances of replacement, which even experienced craftsmen often miss.

Drive device for Nissan Primera P12: circuit and components

Drive design Primera P12 depends on the type of transmission. Basic versions were equipped front wheel drive (FWD), and top-end configurations have a system ATTESA E-TS (all-wheel drive with electronic control). Let's look at both options.

B front-wheel drive in modifications, torque is transmitted from the gearbox to left and right axle shafts, connected to the wheels through CV joints (constant velocity joints). Each axle shaft consists of:

  • 🔧 Inner CV joint (tripod or ball type) - connects to the gearbox differential.
  • 🔗 Vala - transmits torque.
  • 🔧 Outer CV Joint - connects to the wheel hub.
  • 🛡️ Pylnikov — protect the hinges from dirt and moisture.

B all-wheel drive versions are added rear drive shaft (universal drive) going from the transfer case to the rear differential, as well as rear axle shafts with CV joints. System ATTESA E-TS automatically engages the rear axle when the front wheels slip, distributing the torque in a ratio of up to 50:50.

Typical drive malfunctions: symptoms and causes

Drive mechanisms Primera P12 They fail gradually, but the first signs cannot be ignored. Let's consider key symptoms and their possible causes.

Symptom Probable Cause Danger level
Crunching noise when turning (especially when the steering wheel is fully turned) Wear outer CV joint (usually right) ⚠️ High (risk of jamming)
Vibration at speeds of 60–90 km/h Axle shaft imbalance or wear internal CV joint ⚠️⚠️ Critical (may damage the hub)
Clicking noises when starting or changing gears Backlash in tripoid bearing internal CV joint ⚠️ Average
Oil leak from under boot Torn CV boot (requires urgent replacement!) ⚠️⚠️⚠️ Emergency (will lead to the CV joint coming out 500–1000 km away)
Noise when driving in a straight line Wear wheel bearing or axle shafts ⚠️ High

A critical feature of the Primera P12: the right outer CV joint wears out 1.5–2 times faster than the left one due to the greater load when turning (the joint angle is higher). This is due to the suspension design McPherson and weight distribution.

⚠️ Attention! If you hear a metallic grinding sound when moving backwards, this is a sign complete destruction of the CV joint. The vehicle cannot be operated in this condition: debris can damage the hub or brake disc.

Drive diagnostics: how to check CV joints and axle shafts

For an accurate diagnosis, it is not necessary to go to a service station. Most problems can be identified on your own using simple tests.

Checking the outer CV joint

1. Turn the steering wheel all the way left or right.

2. Drive away and listen: crunch when accelerating, indicates wear on the joint.

3. Inspect the boots for cracks or oil stains.

Checking the inner CV joint

1. Raise the car on a lift or jack (be sure to secure it!).

2. Start the engine, turn on D (or 1st gear on a manual transmission) and give a little gas.

3. If you can hear rhythmic clicks — the inner CV joint requires replacement.

Checking the axle shaft for play

1. Jack up the wheel and rock it in a horizontal plane.

2. More play 1–2 mm speaks of wear and tear wheel bearing or the axle shaft itself.

3. Check integrity gearbox seals - An oil leak will indicate damage to the shaft.

Selection of spare parts: original vs analogues

When replacing drive components with Primera P12 owners are faced with a dilemma: to buy original details from Nissan or high-quality analogues. Let's look at the pros and cons of each option.

Original spare parts (articles for P12):

  • 🔹 Axle shaft assembly: 39300-4M000 (left), 39300-4M001 (right).
  • 🔹 Outer CV joint: 39330-4M000.
  • 🔹 Inner CV joint: 39320-4M000 (tripodal).
  • 🔹 Boot: 39381-4M000 (set).

Pros: guaranteed compatibility, resource 100,000+ km. Cons: high price (from 15 000 ₽ for the axle shaft assembly).

Analogs (proven brands):

  • 🔧 GKN (Loebro) — best price/quality balance, resource 80,000–100,000 km.
  • 🔧 SKF — reliable CV joints, but more expensive than analogues.
  • 🔧 Febi or Meyle - budget options (from 4 000 ₽ for CV joint).
  • 🚫 Avoid no-name spare parts - they serve no more 20,000–30,000 km.
⚠️ Attention! When purchasing analogues, be sure to check catalog numbers with your car's VIN. For example, axle shafts for Primera P12 with engine QR20DE (2.0 l) and QR25DE (2.5 l) differ in length!

💡

When replacing a CV joint, always install a new boot and clamps - even if the old one looks intact. Cost of the set 500–800 ₽, and the risk of repeated repairs due to a torn boot is 90%.

Step-by-step replacement of the axle shaft and CV joint on Primera P12

Replacing an axle shaft or CV joint is a task of average complexity, but if you have the tools and skill, it can be done in the garage. Let's look at the process using an example right axle axis (the most vulnerable).

Required tools:

  • 🔧 Set of sockets and keys (10–19 mm).
  • 🔧 Puller for CV joint (or mount).
  • 🔧 Jack and stops.
  • 🔧 Torque wrench (for tightening the hub nut).
  • 🔧 New clamps for anthers.

Work order:

  1. Raise the car, remove the wheel and disconnect brake caliper (hang it on a wire, do not disconnect the hose!).

  2. Unscrew hub nut (tightening torque 250–270 Nm) and remove the brake disc.

  3. Disconnect tie rod end from the steering knuckle.

  4. Press the axle shaft out of the hub using a puller or gentle hammer blows through a wooden spacer.

  5. Remove the inner CV joint from the gearbox by prying it up with a pry bar (be careful with the seal!).

  6. Install a new axle shaft or replace the CV joint, having previously lubricated the splines lubricant for CV joints (For example, Molykote BR2 Plus).

  7. Reassemble everything in reverse order, tightening the hub nut with a torque wrench.

Important nuance: after replacing the axle shaft, be sure to check gearbox oil level — when removing the shaft, some of the oil may leak out.

What to do if the CV joint does not come out of the gearbox?

If the inner CV joint is stuck to the differential, do not hit it with a hammer - you risk damaging the seal. Use a special puller or WD-40 (pour into the joint and wait 10–15 minutes). As a last resort, carefully pry it up with a pry bar, resting against the gearbox housing, and not against the shaft.

Drive maintenance: how to extend service life

Service life of drive mechanisms Primera P12 directly depends on operating conditions and regular maintenance. Follow these guidelines to avoid costly repairs:

  • 🔄 Every 15,000 km inspect the anthers for cracks. Replace them at the slightest damage.
  • 🛢️ Every 60,000 km renew the lubricant in the CV joints (even if the boots are intact). Use lithium grease with graphite.
  • 🚗 Avoid sharp starts with the wheels turned out - this accelerates the wear of the outer CV joints.
  • 🌧️ After driving through deep puddles or salt solutions (in winter), rinse the drive mechanisms with pressurized water.
  • 🔧 When replacing gearbox seals always check the condition of the axle shafts - oil drips on the shaft indicate wear.

A unique feature of the Primera P12: on vehicles with automatic transmission (RE4F03A) axle shafts serve on 20–30% longer than with a manual transmission, thanks to smooth torque transmission. However, when towing or driving off-road, the resource levels out.

💡

Regular checking of boots and lubrication of CV joints allows you to increase their service life by up to 150,000–200,000 km - almost 2 times longer than the “average” service life.

Common mistakes when repairing a drive

Even experienced craftsmen sometimes make mistakes that lead to repeated repairs. Here are the most common:

  1. Using old grease. When replacing a CV joint, some people “save money” by not renewing the lubricant in the boot. This reduces the life of the new joint by 30–40%.

  2. Improper tightening of the hub nut. Weak tightening leads to play, and excessive tightening leads to bearing damage. Use a torque wrench!

  3. Installation of incompatible spare parts. For example, CV joint from Primera P11 looks similar, but has a different angle of operation - this will cause vibration.

  4. Ignoring gearbox seals. If the oil seal is not updated when replacing the axle shaft, the oil will quickly leak out, which will lead to damage to the differential.

  5. Damage to boot during installation. Even a microcrack will lead to dirt getting in and the CV joint failing.

⚠️ Attention! After replacing the axle shaft, be sure to wheel alignment. Even if you didn't touch the tie rods, changing the suspension geometry when removing the wheel can affect the alignment angles.

FAQ: Frequently asked questions about the Nissan Primera P12 drive

Is it possible to drive with a crisp CV joint?

No! Crunch indicates critical wear hinge With further operation, the CV joint may fall apart, which will lead to loss of control. The maximum permissible mileage with such a defect is 500–1000 km (and then at low speed).

Which CV joint breaks more often - internal or external?

On Primera P12 outer right CV joint fails in 3 times more oftenthan internal. This is due to the large operating angles when turning. Inner CV joints usually serve 150,000+ km, if the anthers are intact.

How much does it cost to replace an axle shaft at a service station?

Cost of work in the service:

  • Replacement one axle shaft — 3 000–5 000 ₽.
  • Replacement CV joint (without removing the axle shaft) - 2 000–3 500 ₽.
  • Replacement anther — 1 500–2 500 ₽.

Cost of spare parts:

  • Original axle shaft - 15 000–20 000 ₽.
  • Analogue (GKN) — 6 000–9 000 ₽.
  • CV joint (SKF) — 3 500–5 000 ₽.
What is the difference between axle shafts for manual transmission and automatic transmission?

On Primera P12 axle shafts for mechanical And automatic checkpoint externally identical, but have different lengths of the splined part of the inner CV joint:

  • For Manual transmission (codes FS5R30A, FS6R31A) - the splines are shorter.
  • For Automatic transmission (RE4F03A) - the splines are longer by 5–7 mm.

Installing the “wrong” axle shaft will result in vibrations or the inability to fully lock into the differential.

Is it possible to restore a CV joint without buying a new one?

Theoretically yes, but not recommended. Some workshops offer:

  • Replacement separator and balls (cost 1 500–2 500 ₽).
  • Surfacing of worn tracks (cheap, but unreliable).

However, the service life of a “repaired” CV joint rarely exceeds 20,000 km. For Primera P12 it is more expedient to buy a new analogue (GKN or SKF).
