Nissan Navara NP300

[Gumusut_Amige]

if top side.. paano na pag half tank?

meron munting pump sa loob ng tank apart from the in-line fuel pump.

[dr. d]

while the pipe may be entering the tank from above (for ease of engineering and ease of servicing),
its open tip is somewhere near the bottom of the tank, so's we may higop fuel still, even as the tank is already registering near-empty at the gauge.
but not too bottom... we have to give the water that somehow gets into the tank, somewhere to accumulate and get drained easily, without getting higop-ed by the pipe and freezing our engine..

generic answer.

kuya naman.. fuel filter change na premature? you want to extend the fuel filter life? follow the intervals set by Nissan.

Yes sir, I'd like to follow the manufacturer's recommended interval. but upon inspection of the condition of the filter, I saw it is worthy enough to be replaced even if its still way far from the mileage interval, hence, I call it premature yung pag palit ko. I have no choice but to buy new filter. otherwise I have to bear the burden of huge expenses on fuel system repairs in the future if I leave it that way.

I bow to that doc..

Have any of you guys suffered axle seal leaks on your NP300s? Mine had it at 36K km. The seal was replaced under warranty but I was back to the shop at 39K km for the same problem. It was again replaced but I'm closely observing it. A friend of mine also suffered the same problem on his Terra barely going 6k on his odometer.

Ano symptoms nito?

^Axle end-seal weeps oil. Possible cause of premature wear is vibrations on the driveshaft or failing crossjoints. Mine on D40 was replaced after 10yrs.

[dr. d]

or, the drive shaft ain't perfectly straight anymore.
the very slight but nevertheless excess wiggle as it rotates swiftly, wears down the oil seal fast

puede rin siguro, bad bearing..

There are no symptoms as you drive sir. I suggest you take an occasional look at the brake drums from underneath and if you find it wet with oil then that's it. It has been discussed a lot in the FB site of Team Navara Philippines. It happens quite often to Navaras...and maybe Terras too as what my friend has experienced.

Sir, same axle that was replaced with a new oil seal has leaked again after running around 3k km? Tama yung sinabi ni doc na possible yung axle bearing ay maluwag na. Possible din yung contact surface ng oil seal lip sa axle shaft ay medyo may wear ng kunti. Kaya may variance na ang diameter. Pero 39k km palang parang maaga pa. Tanong ko lang Sir heavy load ba lagi karga mo sa pick up mo?

It looks like this.

Its clear on the pic you posted. sigurado basa na rin ng langis ang brakes mo. If this rear axle oil seal problem happens often on the navaras', then Nissan phils should look into

Yes, sir. After 3,000 km I was back to the dealer with the same problem. Now they fixed it again. I am closely monitoring it though. Some colleagues in TNPI had the seals of their rigs replaced as many as 4 times. Others had their differential assembly replaced entirely because of the same issue.

No, sir. I don't carry heavy loads on my rig, if at all. Be that as it may, I still consider it to be new to suffer such an issue. Our other car is running 140,000 km without worries.

The brakes were fine when the drum was opened as the car was brought to the dealer shortly after the leak was discovered.

Yes sir. I think Nissan Phils knows about the issue. In fairness to Nissan they are prompt in addressing warranty claims. I though believe that they should do more about this. Sooner or later the car would be out of warranty and the problem could still persist with the owner having no recourse but to spend for repairs on his own.

Oh my. Baka ito na yung naririnig kong klug klug sound when decelerating. Coming from the rear right wheel. Masilip nga.

Pasilip mo rin ang cross bearing ng propeller shaft mo pati ang center bearing ng propeller shaft baka may tama ang rubber boot ng center bearing mo. anong mileage na ang Navara mo sir?

12k pa pero napansin ko na ito nung 5k pa lang.

Maraming cause..if the bearing axle are okay..it could be the quality of the rubber seal material Nissan is using or the design profile of the oil seal used in the application kasi recurring na tong problem na to sa mga navaras. with so many owners claiming, I hope Nissan phils is alarmed on this issue so that they can come up with the solution and add it on their service bulletin

4th attempt within 12months/20k kms applicable na lemon law, demand palit buo final drive assy.

i'd probably use another brand of oil seal.
if you keep using the same (defective?) brand...
at least, if you use another brand oil seal, and it finally stops leaking after only a short thousand km, then you have your answer!
but if it still leaks, despite the use of another brand, they you also have your answer! ...it's probably the shaft...
