Left drive seal <em>Nissan Almera G15</em>: how to select and replace without errors

Nissan Almera G15 is a popular sedan that is valued for its reliability and unpretentiousness. However, even such machines have weak points, and one of them is drive shaft seals. The left oil seal, located on the gearbox side, is especially vulnerable: it operates under conditions of high loads, temperature changes and constant contact with transmission oil. Its wear leads to oil leaks, dirt getting into the gearbox and, in the worst case, to failure of the entire drive.

In this article we will look at how determine the malfunction of the left oil seal on Almera G15, what Articles of original and analog spare parts fit, and we'll also give step-by-step replacement instructions taking into account typical mistakes. We will pay special attention to the nuances that even experienced craftsmen often miss - for example, the correct installation of the boot and the choice of sealant for the seat.

Signs of wear on the left drive oil seal on Nissan Almera G15

The first signal about problems with the oil seal is oil stains under the car from the driver's side. But there are other, less obvious symptoms:

• 🔴 Oil on the inside of the wheel or CV joint boot. If after a trip you notice greasy marks on the disc or brake mechanism, this is a sure sign of a leak through the oil seal.
• 🔴 Crunching or grinding noise when turning. When oil from the gearbox gets onto the CV joint, it washes away the lubricant, and the joint begins to work “dry”.
• 🔴 The oil level in the gearbox drops for no apparent reason. If you regularly add transmission fluid, but do not find large leaks, check the drive seals.
• 🔴 Vibration at speeds of 60–80 km/h. A worn oil seal can cause shaft imbalance, which manifests itself as steering wheel wobble.

On Almera G15 with a manual transmission, the left drive oil seal suffers more often than the right one due to design features: the shaft here is longer, and its angle of operation is more critical to seal wear. If you ignore the problem, the oil will begin to wash away the lubricant from the CV joint, which will lead to its complete destruction after 3–5 thousand km.

⚠️ Attention: Do not confuse a leak through the drive seal with a leak at the gearbox seal! To accurately diagnose the problem, clean the gearbox and drive housing from oil, then drive 50–100 km and inspect the parts again. If oil appears on the CV joint boot, the drive oil seal is to blame.

Articles and analogues: which oil seal to choose for replacement

Original left drive oil seal for Nissan Almera G15 (body N17, engines HR16DE And K4M) has an article number 39320-4M000. However, its price (from 1,200 rubles) often forces owners to look for analogues. The table below contains proven substitutes indicating manufacturers and average prices:

Manufacturer	Article	Price, rub.	Features
Nissan (original)	39320-4M000	1 200–1 500	High quality rubber, long service life
Corteco	20016036	450–600	A good budget option, but the tires are harder than the original
SKF	VKDA 35353	700–900	Reinforced spring, suitable for aggressive riding
Elring	503.530	500–700	Soft rubber, but can "leak" at high temperatures
Febi	06865	350–500	Budget option, suitable for temporary replacement

When choosing an analogue, pay attention to sealing lip material. The best option is oil seals with fluorine rubber (FKM), which is resistant to high temperatures and aggressive oils. Cheap seals made of nitrile rubber (NBR) last 2–3 times less.

Also check direction of rotation oil seal - on Almera G15 left drive rotates counterclockwise (when viewed from the wheel side). There should be an arrow or inscription on the seal CCW (counter-clockwise).

Tools and preparation for replacing the oil seal

To replace the left drive oil seal with Nissan Almera G15 you will need:

• 🔧 Special oil seal remover (or a flathead screwdriver and a hammer).
• 🔧 Torque wrench for tightening the drive nut (torque 220–240 Nm).
• 🔧 Socket heads at 17, 19 and 32 mm.
• 🔧 Sealant (For example, Loctite 574 or ABRO 99-003) for the seat.
• 🔧 New oil seal And CV boot (it is recommended to change together).
• 🔧 Gear oil (for topping up after work).

Before starting work, complete the following steps:

Drive the car onto a pit or a lift|Drain the oil from the gearbox (about 1 liter)|Clean the gearbox housing from dirt with a wire brush|Disconnect the negative terminal of the battery|Prepare new parts and tools-->

Pay special attention shaft fixation. After removing the drive, do not turn it or pull it too much - this can damage the inner CV joint. If the shaft has “jumped out” of the box, the gearbox will need to be disassembled to install the retaining ring.

⚠️ Attention: Do not use WD-40 or other penetrating lubricants to facilitate oil seal removal! They destroy the rubber of the new seal. To clean the seat, use only gasoline or white spirit.

Step-by-step instructions for replacing the left drive seal

The process of replacing the oil seal Almera G15 takes 2–3 hours. Follow the instructions to avoid errors:

1. Remove the wheel and engine protection. Unscrew the hub nut (you will need a 32mm socket and a long lever). Do not remove the nut completely - just loosen it.

2. Disconnect the CV joint from the hub. To do this, knock out the hinge pin from the steering knuckle using a mounting blade. Be careful not to damage the boot!

3. Remove the drive from the gearbox. Carefully pry the shaft with a screwdriver and pull it towards you. If the oil seal is stuck, do not use excessive force - it is better to use a puller.

4. Remove the old oil seal. Use a screwdriver to pry it from the outside and knock it out with a hammer through the wooden spacer. Clean the seat from any remaining sealant and oil.

5. Install a new oil seal. Lubricate its edge with transmission oil and press it in using a mandrel (for example, an old oil seal or pipe of a suitable diameter). Make sure it sits straight, without distortion.

6. Reassemble everything in reverse order. When installing the drive in the gearbox, you will hear a characteristic click - this means that the shaft splines are engaged.

After assembly be sure to check the oil level in the gearbox and top up if necessary. For the first 100 km, avoid sudden starts and high speeds - this will help the new oil seal to “get used to”.

What to do if the oil seal leaks after replacement?

If after installing a new oil seal the oil leak continues, the reasons may be the following:

1. **Distortion during installation** - the oil seal is seated crookedly, and the edge does not fit tightly to the shaft.

2. **Damaged seating surface** on the shaft (scuffing, corrosion).

3. **Wrong direction of rotation** - the oil seal is installed backwards.

4. **Poor quality of rubber** - cheap analogues can harden at low temperatures.

In this case, repeated replacement will be required with a thorough diagnosis of the shaft and gearbox housing.

Typical mistakes when replacing an oil seal and how to avoid them

Even experienced technicians sometimes make mistakes that lead to repeated leaks or damage to the gearbox. Here are the most common:

• ❌ Using a hammer without a spacer when pressing the oil seal. This leads to deformation of the metal frame and subsequent leakage.
• ❌ Lack of sealant on the seat. On Almera G15 The gearbox housing is aluminum, and without sealant micro leaks are possible.
• ❌ Reusing an old CV boot. Rubber loses its elasticity over time, and the boot can tear after 1–2 thousand km.
• ❌ Improper torque of the hub nut. Weak tightening leads to play, and excessive tightening leads to bearing damage.

Another critical error - ignoring the condition of the CV joint. If, when replacing the oil seal, you notice that the grease in the joint has turned black or contains metal shavings, it also needs to be replaced. Otherwise, after 5–10 thousand km you will experience a crunch when turning and expensive repairs.

When the entire drive needs to be replaced, not just the oil seal

In some cases, replacing one seal will not solve the problem. A complete drive replacement is necessary if:

• 🔧 Shaft has visible scoring or corrosion at the point of contact with the oil seal. Even a new oil seal will not be able to hermetically seal the damaged surface.
• 🔧 The CV joint makes a crunching noise or play when checking. This means that the hinge is worn out and its life is running out.
• 🔧 The boot is torn or cracked. In this case, dirt has already entered the CV joint, and its service life is reduced significantly.
• 🔧 The drive was deformed (for example, after an accident or careless repair). Even a slight bend of the shaft leads to vibrations and accelerated wear of the oil seal.

Cost of a new drive for Almera G15 (For example, GKN or NTN) starts from 8,000 rubles. However, this is cheaper than repairing the transmission due to dirt entering through a leaky seal. When purchasing a drive, pay attention to complete set — the box should contain: hub nut, retaining ring, anthers And clamps.

⚠️ Attention: There are many fake branded drives on the market GKN And LOBRU>. Original parts have a laser engraved logo and are supplied in branded packaging with a hologram.

Prevention: how to extend the life of the drive oil seal

The service life of the left drive oil seal is Almera G15 can be increased if you follow simple recommendations:

• 🛠️ Check the oil level in the gearbox every 10,000 km. A low level accelerates oil seal wear due to overheating.
• 🛠️ Avoid abrupt starts with the wheels turned out. This creates a peak load on the CV joint and oil seal.
• 🛠️ Wash the gearbox housing when changing the oil. Dirt and sand act as an abrasive, destroying the rubber of the seal.
• 🛠️ Use quality gear oil (For example, Nissan KE908-99931 or Motul Gear 300). Cheap oils contain aggressive additives that corrode rubber.

Also note driving style. Frequent trips off-road or in deep puddles reduce the service life of oil seals by 2–3 times. If you operate your machine under severe conditions, reduce the oil seal inspection interval to 30,000 km.

💡

After replacing the oil seal, apply a thin layer lithium grease on the inside of the CV joint boot. This will prevent the rubber from sticking to the metal and will extend the life of the boot.

FAQ: Frequently asked questions about the drive seal Nissan Almera G15

Is it possible to drive with the current drive seal?

Short term (1-2 weeks) - yes, but only if oil leakage is minimal. However, remember: the longer you delay replacement, the higher the risk of dirt getting into the gearbox and CV joint failure. If there is an intense leak (more than 100 ml of oil per week), you should not drive - this will lead to gearbox oil starvation.

What sealant is best to use for the oil seal?

Optimal options - Loctite 574 (anaerobic) or ABRO 99-003 (silicone). Do not use solvent-based sealants (for example, "Moment") - they can corrode the rubber of the oil seal. Apply a thin layer only to the seating surface of the gearbox housing.

Is it necessary to change the gearbox oil after replacing the oil seal?

If the oil is clean and its level is normal, it is enough to add the lost volume. A complete oil change is recommended if:

• The oil is blackened or has metal shavings.
• More than 60,000 km have passed since the last replacement.
• Dirt or water has entered the gearbox (for example, due to a damaged boot).

For Almera G15 with manual transmission you will need 2.8–3 liters of oil API GL-4, for automatic transmission - 6–7 liters Dexron III.

What is the difference between replacing an oil seal on an automatic and a manual?

On Almera G15 with automatic transmission (DP0 or DP2) replacing the left oil seal is more difficult due to:

• The need to remove the axle shaft.
• Risk of damage to the torque converter if the shaft is removed inaccurately.
• Larger volume of oil in the box (3-4 liters will need to be drained).

Without experience, it is better to contact a service center - errors when assembling the automatic transmission can lead to its failure.

How long does the drive oil seal last on Almera G15?

The service life of the original oil seal is 80,000–100,000 km. Analogs last less:

• Corteco/Febi — 50,000–70,000 km.
• SKF — 70,000–90,000 km.

The service life depends on operating conditions: in the city, oil seals wear out faster due to frequent starts and turns.
