u determined which part of the engine.?
Belts usually make some noise, i changed mine cuz of this
and my turbo whirrs a bit around 1600-1800rpm

[lighthammer]

on my navara, at low RPM 1500-1800, I usually hear a "weeooorrrrr" humming kinda noise coming from the engine bay, and as the turbo spools up at 2000rpm, the noise becomes a whistling.

I figured it was the turbo as it was spooling at low speeds, remember it's a VGT (variable geometry turbo) so at low speeds, the Vanes on the turbo are angled differently than at higher RPMs, - this is to help build boost a lil faster than with a traditional fixed-vane turbo.

I hear the same "weeooowwww" noise from one of my neighbour's automatic Navara's as they pass by every morning.


If it's not that noise, call this no: 374 9339 (ask for James) and he'll sort you out. If you can bring the Navara on a certain day when I'm in the garage too, I can help you diagnose the noise.

[bt50]

Light hammer that is the noise self lol. Thanks

[lighthammer]

yeah thats the turbo right thurrr mang, it goes "wweeeeooorrrrrr" esp when the engine cold and u now rolling outta ur garaje.

I personally think it sounds cool, like a big beast starting to wake up and stretching out.
Have you seen the size of the turbo's in the Navara and frontier? they're huge, compared to the mazzies and fords (no offense) but that's where the navara's galactic power comes from.


.. then again, it may be the timing chain making the sound... i dunno lol.

fellas, my van is from the firm and i have been having some issues with tire cutting. after the stock tires were changed, i went to toyo proxies from mileage mack and had to take them off because of heavy rolling noise after 2 months. i then changed to kumho ecsta and same problem only this time its worst (and the tire noise is now unbearable especially when slowing down). the kumho tire feels wavy and jumpy only after 2 month of usage. i have taken the van to numerous tires shops and the last being today which all showed that nothing was/is wrong with the suspension. do you guys think it may be shocks that needs to be changed???? the van i currently 44,000kms and feb 2012 will make two yrs since i have owned the vehicle. btw, i have stock rims and tires are 275/70/16..

i am also very disgusted by n&m san fernando service dept, had my battery stolen at 40,000kms....

thank you!!!!

275 70 16 ???? do u have any rubbing issues with that ?? oh i am waiting delivery of a 4x4 nav sold my 4x2 hopefully before christmas the sales rep says

[Aaron 2NR]

had that size on my navara and no issue....carry the van mileage mack and let them do a full suspension check...

[sliderz1]

i have the 275/70/16 Proxes S/T. They do humm while drivin but to me its tolerable. Quite good wrt to traction and road comfort.

@ravist
have you checked your cradle bushings, joints, shocks and maybe even the stabilizer bar rubbers?

@gready123456
tons of space in there still. i might opt for 75 series next time around

i had a 4x2 with 255 70 16 continential tyres had no problem with those

i think the 4x4 are coming with 255 70 16 Dunlop tires i have heard bad thing about these tires ,

the interior is also different the color is a dark gray . when i bought the 4x2 there were two options light gray and beige . not to keen on the dark gray but say what

any one know where i can get a balancer unit to buy ( for the engine ) except N&M

[sliderz1]

yep.......but they wear down pretty quickly

did u trade in your 4x2?

[lighthammer]

Do not, under any circumstances, take these off-roading. They are highway rated tyres and should be used for highway only. Take it from me, I took my navara offroading only 3 weeks after I bought it while using the Dunlop Grantrek - got stuck on a muddy hillside with no traction in a huge rut.


Waste of time tyres.
Replace them asap.

BTW, those dunlops wear down pretty fast, and won't last much longer than 35,000 km.

[ravist]

yes, i have checked all suspension parts by numerous people and they all tell me that i have no issues... the only thing to check are the shocks. my van is very rugged and i feel everything on the road, but apart from that, no major issues.... i am just frustrated with the heavy rolling noise & will like to get the wavy tire cutting sorted out. the van is going in n&m tomorrow (8/12/11) @ lady young branch... hope to get a good outcome..

thanks fellas

i had the say issues with my car turned out the khumo i had were all bad changed two sets before it was sorted out the tires had some strange ware patters with swirl looking pattern on the contact patch of the tire it turned out the tires were bad probably a bad batch or some . it was so bad i swore the bearing were going bad i was


please let up know if u get it sorted out

good luck man

[ravist]

What is a good brand and type of tire for %100 on road (higway) driving?? I tried Dunlop, Toyo Proxies and Kumho Ecsta. I am seriously thinking about going RoadStone 275/70/16 because is a fedup of the heavy rolling noise..

[Aaron 2NR]

i was very pleased with my toyo A/T

[sliderz1]

@ravist
confirmed its the tyres?

[ravist]

n&m morvant called me this evening and told me that nothing was/is wrong with the suspension, shocks or chassis and alignment was perfect. they said that my tires were slightly deflated (29psi nitrogen) and that could have been causing the noise and heavy rolling. tomorrow i am expected to road test again with a mechanic so i'll see if any progress was made since they pressured the tires to 35psi....

things to consider;
1) the van is already rugged at 29psi
2) should i change tires now since the two front have eaten away badly (only 2 mhts)
3) tell n&m to hdmc and change the shocks myself
4) monitor the vehicle until the end of the year and try to tackle this for the new year

one question fellas, ah tire man from south told me that the navs are really heavy and the a "v" type tire is not suited thats why i am having the heavy rolling sound...i should go with a straight beaded tire and my problem will be solved.... does this make sense??

please let me know what you guys think...

[sliderz1]

put them in the back
3) tell n&m to hdmc and change the shocks myself
if your warranty period is done. go for it
4) monitor the vehicle until the end of the year and try to tackle this for the new year
resolve as soon as you can

can u post some pics of the cut tyres? id like to see what you're looking at

[gready123456]

Any one know where i can get engine parts ?? online or locally

the part is called the Balancer unit

thanks

[ravist]

after receiving the van from n&m this morning, i can hastily say that they did absolutely nothing with my vehicle and heavy rolling noise is still there, ah little less but still there. the tires are now 35psi.... the van is riding rough and more rugged and i am displeased with the ride...

i am going to drop the psi to 32 and probably change tires early next year to a roadstone...

i worked intermittently in peru 2010/2011 and most of the navaras and other 4x4s there used goodyear fortera....maybe i will give it a try and see how it goes...
i had them on my frontier prior to my nav and they were very rugged/rough....

thanks fellas for all your advise and assistance and will try to post some pics of the tires as soon as i can...

I just installed some michlelin latitude tour hp 275/70/16 (10% off road/90% on road) from quick service and they are running beautiful.... no pulling, no shimming, no noise.... feels like ah new nav again....

however, they look like they will wear down pretty quickly but i will have to wait & see... i also decided not to go with the goodyear because the tire is too rugged....

laterz..

Oh i forgot to mention that shimming u might be feeling might be a problem with the steering wheel there is a vibration i got from the steering wheel a while ago thought it was the rack had massy checked it out they said it was good i still got the shimming but on the next service i the explained the problem to them , when turning or going through rough you feel a vibration the the steering wheel it turns out this is a common problem with the nav and they usually insulate the stearin wheel area to stop the vibration it works so u could check out that also .

here is the navara user manual

[gready123456]

N&M stress they have limited color options yess i initially wanted a white could not get that they tell me they have an ash gray . was no to happy with that color told my sales rep i would take a black she said she have to check to see if she can swap colors with another customer . but i did eventually get the black . i wanted to wait on the white but she said they not sure as to when the next set of navaras are coming in it might be any where from February to june as Thailand is under flood its hard to get vehicles . i just not looking forward to cleaning that van black takes alot more effort to keep clean . this N&M i tell u why i could not just get my white stups.

my new michelin tires are cutting front left on the outside and started feathering after 3 days of installing.... i decided to take it to master serv at balmain couva and they discovered that the two front shocks are leaking... i hope to get this resolved as soon as possible and the mechs at n&m morvant said nothing was wrong after keeping the vehicle for 3 days..

[lighthammer]

Ravist - N&M usually wont do much for u esp if the truck under warranty and they have to spend a crap load to replace parts. I'm surprised they didn't try to hustle u out of it.


Give James a call 374-9339 by Wednesday this week coming, he'll sort you out.
Or give Chris a call - 374 8542
You don't have to buy an ARB kit or anything, but he'll help you diagnose the problem and source parts for u as well.

[ravist]

lighthammer, i think i am getting through with my van...

i have to say honestly that the fellas (mr. mohan & his staff) at master serv balmain are willing and not beating round-d bush. they told me that this week they will try to get the shock from sando which they did and about 1 hour ago, i visited and saw them taking out the damaged shock. i think i will be doing all my services from now on at that branch..

will give an update soon as to how the nav is riding..
thanks fellas and merry christmas.....

[gready123456]

I have received my new 4x4 auto 3 days ago i have one problem if i am cruising and take my foot of the accelerator then back on the accelerator again to achieve an moderate acceleration i am hearing a noise (clank) then a i feel a vibration it seems to be coming from rear end i think . i only hear this noise if i am cruising and suddenly accelerate . i am on 400km i will have to speak to NM service department about sorting out this. I am thinking it could be backlash in the rear end but my 4x2 never made any noise like this and did have a slight backlash.

Has any one with a 4x4 auto had this problem ????

[Aaron 2NR]

It's the backlash on the diff
