Knocking noise in my Navara.

[biggy82]

There is no oil pump problem in the Nav and whoever pushing that talk issa @ss

Ah betting anything that the 3 vans with the broken turbo shafts either don't have turbo timers or don't use them properly...

I hear a similar sound at around 3000 rpm especially when cold. Like a chain slipping or something coming from the engine. The turbo is also starting to whistle loudly and the diff is knocking big time. These are just current problems on this vehicle. We have had everything from the cigarette lighter and ceiling clips falling off to a bad pulley at 3000k to terrible engine knocking. The vehicle is doing under 25k now. Proper piece of junk.

It's a diesel engine, it's always going to knock and rattle a little more when it's cold and now started.

We have:
- 2 navara's
- a 3.0 ZD30T frontier
- a 2.5L turbo K34 L200

and all of them rattle like old tractors when cold. As soon as the engine warms up 3 mins later the rattle is gone and idle is smooth.
It's a basic trait of all diesel engines.

Did you put in a K&N air filter? You can usually hear the turbo on the Navara, whether you have a stock air filter or K&N (it's a bit louder with the K&N).
Diff knocking? Did you check the cv boots? Which diff is it?

These are just current problems on this vehicle. We have had everything from the cigarette lighter and ceiling clips falling off to a bad pulley at 3000k to terrible engine knocking. The vehicle is doing under 25k now. Proper piece of junk.

Depends on how you're using and maintaining the vehicle. So far you haven't mentioned how regular you maintain the vehicle (and saying "oil change every 5000km isn't enough - I'm taking about proper maintenance to address every issue that pops up, and not leaving it for later and allowing them to build up). Can't just write off a van, no matter what brand it is, if it's not maintained properly, including beyond the regular scheduled maintenance.









*update on the noise..

Turns out it was a loose clutch hose.
Took the truck for the 20,000km servicing at N&M and told them about the noise.
Said on the invoice that they secured a clutch line and now the noise is gone.


Yay for good service!
Boo for expensive prices!


No problems at all with the navara - now pushing 25,600KM and everything is smooth sailing.
No turbo issues, no problems with cigarette lighter or clips, and no pulley issues anywhere.

ant that navara does get some good licks too, mud bathing almost every week...........

Thanks lighthammer for the response. I've had pickups before and actually have driven two other Navara's already and the knock isnt as loud. I'm wondering if N&M is using the right oil. The service is done fully at N&M and always on time.

The vehicle is used for what it's designed for. I don't expect things to be dropping off the roof or the dashboard under normal use. Even the power window switch panel is unsticking!!

Everything on the car is original and there is no K&N filter. We told N&M about the diff and they have not been able to fix it for two services now. There are many Navara owners with this problem. As for what type of diff it is I have no idea.. It's a 4x4 Automatic bought at N&M end of last year. Is this normal?

As for good service I want to disagree. The waits are long and they do not give a courtesy vehicle if the car is brought in for defects. I waited 1.5 hrs for them to wash the vehicle once and had to climb down the stairs to go find it parked and noone was attending to it. When they finally washed it there were swirl marks on the entire body of the vehicle. If I'm paying $3000 for a service I expect better. In my case I'm pushed in a corner to continue servicing there so that I have a case when things go wrong. I've overheard the stories they give to customers in the waiting room and it's very worrying.

As for writing off the van, unfortunately after spending 240,000 for a pickup truck and getting this cheap piece of junk I would have to be crazy to set foot in a Nissan showroom to look at pickups again. And honestly I don't know what the solution is. The good folks at Toyota think they're selling gold on 4 wheels and Southern Sales is another jokey outfit. Maybe next time I'll try a Ranger. Yes you don't have these problems and probably many people dont, but the fact of the matter is, I got a bad deal, and unless N&M says, 'hey most of our Navara's work flawlessly, please accept our apologies and let us replace this vehicle for you'...which will NEVER happen, I wont be buying anything from them again.

[sliderz1]

any more info about the' diff knocking''??

[civic minded]

that's real said dread but i think you will get these with any brand you buy - even the rangers give some problems. Me personally have absolutely no problems since i bought it (doing 49K right now). But i am hearing some others having brake issues and transmission problems.
What you may need to do is confront management at N&M about your complaints and demand a solution. Make some noise, threaten them, You as a customer is entitled to good service and refuse to pay till you get it.

[sureshot_james]

I had a customer come in with this same problem. Took me about ten minutes to find the SNAKE that got stuck in the turbo shroud and radiator fan.

[lighthammer]

W.R.T. the "diff-knocking" - there is a recorded phenomenon called "Diff Backlash" that occurs in the automatic models of the Navara.

Basically whenever you're stopping at a red traffic light, and the transmission downshifts into 1st gear, a "backlash" can be felt as this happens. This problem occurs in some automatic models, and is benign. It also usually disappears by the time the truck gets older with some mileage, so it's nothing to be concerned about.

Does that describe your problem?

[sureshot_james]

when you gonna bring that black truck in to me so I can make it the black beast? lift kit bumper winch snorkel and a rear locker.



YOU KNOW YOU WANT TO

This is exactly the same thing N&M told me and they even said that the salespeople should start mentioning this because they are having tons of complaints about it.

Turns out also my Turbo needs to be changed. Is overheating a problem on these cars still? Is a turbo timer really necessary?

Also has anyone looked under the Aeroklas tray liner that they supplied with some of them? The paint is totally ruined because they don't put the padding below. Beware of rust. If you're less than a year take it back and demand they tar it and put proper padding.

Also has anyone heard a chain type sound coming from the engine when you floor the accelerator? N&M is saying that's the diesel pump pushing more in times of high demand. Not sure if I believe that. Will do some research on this.

^ turbo damage already??

wow and i use to complain about my lil suspension squeaking noise lol

[civic minded]

i dont think i ever floored the ranger - damn i need to try that sometimes

[lighthammer]

Yup, very common complaint, in all the Thailand-made navaras (Serial No: VNxxxxxx)
Nissan has no official fix for it, other than replace the diff and trans fluid at 25,000 and 50,000km. USually goes away by itself though.

Not really a problem with the Navara, but a TurboTimer is still a good insurance policy esp. if you're in a rush and not willing to wait 30 sec before switching off. The Garret turbocharger in both the Frontier & Navara is HUGE, hence all the power (and turbo lag!), but generates a LOT of heat. I'd hate to cook that turbo, esp after doing a highway run and then switching off in a mall. I'd still get it, better be safe than sorry IMO. Plus you'll get a nice volt-meter so you'll know when ur battery needs changing out.

Also has anyone looked under the Aeroklas tray liner that they supplied with some of them? The paint is totally ruined because they don't put the padding below. Beware of rust. If you're less than a year take it back and demand they tar it and put proper padding.

Another common complaint with N&M before they switched around their mid-level management in 2009-2010. They used to take a few shortcuts, and have seen some guys on trinituner with navara's that had badly fitted Aeroklas liners. They've improved now, the installer they have now does a better job, but it's still a good idea to check under your liner for rust.

I personally prefer the spray-on type liner, less problems with Rust and their installed did a decent job with mine when I bought the Navara (except for a couple drip-spots). It's almost as tough as the plastic drop-in, and if it starts to chip and wear, I can just paint back over the spot with black paint or spray-on liner.

Also has anyone heard a chain type sound coming from the engine when you floor the accelerator? N&M is saying that's the diesel pump pushing more in times of high demand. Not sure if I believe that. Will do some research on this.

Hmmm... that's a strange one. Could be the diesel pump but unlikely. Also could be turbo-whine, which is normal. This will take some looking into, maybe have a mech do some RPM speed-tests with the truck jacked up.

[civic minded]

i still think the navara is one of the better quality trucks out there - their rating is on par with toyota and Mitsubushi. You cant go wrong with Japanese...
