Inner CV joint <em>Nissan Juke</em>: symptoms of malfunction and step-by-step replacement

Inner CV joint (constant velocity joint) on Nissan Juke - a critical element of the transmission that ensures the transfer of torque from the gearbox to the wheels at variable angles. Despite the structural strength, this unit is subject to wear, especially during aggressive driving or operation on bad roads. Unlike the external CV joint, the internal one more often fails due to dirt entering through a damaged boot or natural wear of the balls and races.

Owners Juke (especially models F15 And J10 with engines HR16DE or MR16DDT) often encounter a characteristic crunching sound when cornering or accelerating. However, diagnosing an internal CV joint is more difficult than an external one: its sounds can be masked as suspension or gearbox malfunctions. In this article we will look at how to accurately identify the problem, select high-quality spare parts and replace the unit yourself - taking into account the nuances of the design Nissan Juke.

How does the internal CV joint work? Nissan Juke and why does it break?

Inner CV joint on Juke belongs to the type tripods (as opposed to external ball). Its design includes:

• 🔧 Three-flute housing — fixed on the gearbox shaft.
• 🔄 Tripod with rollers — provides smooth gliding when changing angles.
• 🛡️ Boot - protects against dirt, but often breaks due to overheating or mechanical damage.
• 🔗 Retaining ring - holds the assembly on the shaft.

Main causes of wear:

1. Boot rupture — leads to the ingress of abrasive particles and washout of the lubricant. On Juke The boots of the inner CV joints are less protected than the outer ones due to their proximity to the exhaust system outlet.
2. Natural wear and tear — the resource of the tripod CV joint is 120–150 thousand km, but when driving off-road it is reduced to 80–100 thousand km.
3. Incorrect installation - if during replacement the tightening torque of the nuts is not observed (220–250 Nm for Juke), the unit will quickly fail.

Feature Nissan Juke - compact wheelbase and high torque on turbocharged versions (MR16DDT). This increases the load on the inner CV joints during sudden starts. For example, on cars with CVT Xtronic wear is accelerated due to the absence of “jerks” when changing gears - the unit operates in constant load mode.

Signs of a faulty internal CV joint: how to distinguish it from other breakdowns

Symptoms of wear on the inner CV joint Juke often confused with wheel or transmission bearing failures. Key differences:

Symptom	Inner CV joint	External CV joint	Wheel bearing
Crunching sound when moving	On straight when accelerating or releasing gas	On corners under load	Constant hum that gets worse when you turn the steering wheel
Vibration	Feels in floor or gear lever	Gives to steering wheel when turning	Vibration on all speeds, even in neutral
When it appears	When engine acceleration/braking	When maximum wheel turn	Constantly, intensifies with increasing speed

On Nissan Juke with all-wheel drive (4WD) diagnostics becomes more complicated: the crunching sound can come from the transfer case or rear gearbox. To pinpoint the source:

1. Raise the car on a lift or hang the front axle.
2. Turn on Drive and slowly increase the speed to 2000–2500 rpm.
3. The assistant should listen to the sound from the wheels and gearbox. A crunching noise from the front when the wheels are in a straight position is a sign of an internal CV joint.

Diagnostics of the internal CV joint: step-by-step instructions

For an accurate diagnosis, you will need an inspection hole or a lift. Follow the algorithm:

Visual inspection of anthers for cracks and tears|

Checking the shaft play (rock the shaft by hand - play more than 1 mm is unacceptable) |

Listening to a crunching sound when the suspended wheel rotates (an assistant speeds up the engine)|

Check the grease (if the boot is torn, the grease will be black with metal particles) -->

Pay special attention to the condition retaining ring - on Juke it often becomes deformed during unqualified repairs. If the ring is bent, the CV joint will “walk” on the shaft, which will lead to accelerated wear of the tripod.

To check without a lift:

1. Turn the steering wheel all the way left/right.
2. Drive away and listen: if a crunching sound appears when direct wheel position - the inner CV joint is to blame.
3. Repeat the maneuver in reverse gear - the sound should increase.

What to do if there is a crunch, but the boot is intact?

In this case, the problem may lie in wear of the tripod itself or corrosion of the housing grooves. On Juke With a mileage of more than 100 thousand km, the rollers often become worn out - they become oval. The only solution is to replace the assembly.

Selection of spare parts: original vs analogues for Nissan Juke

When purchasing an internal CV joint for Juke consider:

• 🔧 Original articles:
  • 39310-4M000 - for models with HR16DE (1.6 l, 117 hp).
  • 39310-4M00A - for MR16DDT (1.6 l, turbo, 190 hp).
• 🔄 High-quality analogues:
  • GKN (Loebro) - art. ADG00234 (full set with dust cover).
  • SKF - art. VKJA 6636 (reinforced tripod for turbo versions).
  • Febi - art. 24360 (a budget option, but requires a mandatory check of the play before installation).

What to look for when purchasing:

⚠️ Attention: On Juke with all-wheel drive (AWD) internal CV joints have a reinforced design (the article ends with 4M00B). Installing a "front-wheel drive" unit on 4WD will lead to its destruction after 10–15 thousand km.

Selection tips:

• 🛒 Buy a CV joint assembled with a boot and clamps - a separate replacement for the boot Juke impractical due to the complexity of dismantling.
• 🔍 Check the presence of grease in the kit - for tripod CV joints Nissan requires special lubricant Molykote BR2 Plus (art. 999MP-AM002).
• 📏 Compare the length of the shaft - on restyled Juke (after 2014) the shaft is 15 mm shorter.

Step-by-step replacement of the inner CV joint with Nissan Juke

To replace you will need:

• 🔧 Set of sockets and wrench 32 mm for the hub nut.
• 🔨 Retaining ring remover and hammer.
• 🛠 Torque wrench (nut tightening torque - 220 Nm).
• 🧴 Lubrication Molykote BR2 Plus (200 g).

Instructions:

1. Remove the wheel and unscrew the hub nut (first loosen it on a car with the handbrake on).
2. Disconnect the steering knuckle and ball joint from the steering knuckle.
3. Press the CV joint out of the hub using a puller or pry bar (do not hit the shaft with a hammer!).
4. Remove the retaining ring from the gearbox shaft and slide the boot.
5. Mark the shaft and CV joint housing with a marker - this will help maintain balance during reassembly.
6. Use a puller or press to remove the old CV joint. Install a new one, first filling the boot with grease (100–120 g).
7. Tighten the hub nut with a torque wrench and check for any play.

Typical replacement mistakes:

• 🚫 Retightening the nuts - leads to deformation of the retaining ring.
• 🚫 Using regular lubricant (For example, Litol-24) - tripod CV joints require a special composition.
• 🚫 No labels on the shaft - may cause vibration at higher speeds 100 km/h.

Repair cost: service station vs independent replacement

Prices for replacing the inner CV joint with Nissan Juke vary depending on the region and type of service station:

Service type	Cost of work (rub.)	Cost of spare parts (RUB)	Total (RUB)
Official dealer	8 000–12 000	12,000–18,000 (original)	20 000–30 000
Unofficial service	3 500–6 000	5,000–9,000 (analog)	8 500–15 000
On your own	—	4 000–7 000	4 000–7 000

The savings when repairing yourself are obvious, but consider the risks:

• 🔧 Without experience, it is easy to damage the boot during installation, which will lead to repeated repairs after 5-10 thousand km.
• 🔨 Incorrect tightening of the nuts can cause vibration or breakage of the shaft while driving.
• 🛠 On Juke with AWD Special equipment is required to align the rear gearbox after removing the drive shaft.

If you decide to contact a service station, choose a service with experience working with Nissan. For example, in Moscow and St. Petersburg the following are recommended:

• Nissan Service Center (official dealers with 1 year warranty).
• JapKo — specialize in Japanese cars, 6 month warranty.
• Auto repair center "ShRUS-MASTER" — narrow-profile service for drive shafts.

Prevention: how to extend the life of the internal CV joint by Nissan Juke

The service life of the inner CV joint can be increased by following simple rules:

Check the boots every 15 thousand km or before long trips|

Avoid sudden starts with the wheels turned out (especially on turbo versions)|

Wash wheel arches in winter - salt accelerates shaft corrosion |

Use only original grease or analogues with molybdenum|

On Juke with CVT It is especially important to avoid slipping - the box transmits high torque at low speeds, which increases the load on the CV joints. If you often drive off-road, install protection for the crankcase and anthers (for example, from Cusco or Whiteline).

Signs that it’s time to check the CV joint even without a crunch:

• 🔧 Appearance oil stains under the boot is a sign of a rupture.
• 🔄 Clicks when switching from Drive on Reverse.
• 🛡️ Uneven tire wear - may indicate shaft play.

Frequently asked questions about the internal CV joint Nissan Juke

Is it possible to drive with a crisp CV joint?

Short term - yes, but not worth the risk. On Juke A worn inner CV joint can lock up during sudden acceleration, leading to a broken shaft or damage to the transmission. Maximum mileage with crunch - 500–1000 km, but only if there are no vibrations or oil leaks.

Which CV joint breaks more often: left or right?

On Juke with HR16DE (front-wheel drive) fails more often right internal CV joint due to greater load when cornering. On all-wheel drive versions, wear is symmetrical, but the left CV joint may suffer from dirt from the exhaust system.

Is it possible to replace only the boot without removing the CV joint?

Technically possible, but impractical. On Juke To replace the inner CV joint boot, you need to remove the shaft, and this is 80% of the work required to completely replace the unit. If the CV joint is already crunching, the savings are 1,500–2,000 rubles. is not justified - after 10–20 thousand km you will have to repeat the procedure.

What is the difference between CV joints for Juke with mechanics and CVT?

Structurally - nothing. The only difference is shaft length: on models with CVT the shaft is 5–7 mm shorter due to the compactness of the box. The CV joint articles are the same, but when purchasing, check the type of gearbox. For example, for Juke 1.6 MT fits art. 39310-4M000, and for CVT — 39310-4M00A.

What lubricant should I use for a tripod CV joint?

The best option is Molykote BR2 Plus (art. 999MP-AM002). Alternatives:

• SKF LGMT 2 — universal lubricant for tripod CV joints.
• Loctite LB 8106 — with increased heat resistance (up to 180°C).

Do not use CV joint-4 or Litol-24 - they cannot withstand the loads and temperatures characteristic of Juke with a turbo engine.
