Are you getting the screeching sound from the bearings so that is why you are going to change them out?

[jhonnieblue]

I think some of the sounds coning from the bonnet latch..I'll grease that tom..but when I'm cornering I'm hearing a grating kinda noise... Shocks were changed last week and were dead..so I'm kinda concerned may be the bushings in the back.

[Kenjo]

Check the wheel bearings also if it's a loud sound, I think you basically have to jack up the tyres and rotate them by hand to hear if there are any grating noises or if there is any side play of the tyres from the little bit I know.

[jhonnieblue]

Well I aligned right after I did shocks..they checked the bearings got no play in it...just thought it would be good to check the bushings..van now at 125k

[cheese pie]

Anyone ever grease the suspension DIY? Wanna know what kinda grease to buy and where

im also interested in this

[*KRONIK*]

fellaz...

i have a old d22 frontier (singe cab) and need the back springs re-tensioned

any suggestion as to where i can have this done??

also

i believe the bushing in the spring needs to be replaced also
any particular one you all can recommend??

[Captain Awesome]

I've been advised based on the issue I'm getting that I may have had a boost leak ever since I had a new turbo fitted last year.

Anyone knows where I can have same checked? Thanks

[Captain Awesome]

no one?

So I read this entire thread over the last couple days in an attempt to see if blowby/back pressuring is an issue with navaras but I only came across 1 single comment about it and no one responded.But I would still like to know if any nav owners are having an isssue with it and if so, what problem is it causing if any at all?

[whiteknight1431]

Hey guys can I swap out my diff with an automatic 4x4 nav LSD diff? I have the manual 4x4 and you know it doesn't come LSD from Neal and Massy.

[Supra GT-FOUR]

Whiteknight from my understanding the auto navaras dont have a traditional viscous LSD. They employ an electronic means of limited slip. It uses braking to achieve this after monitoring rear wheel rotations. The other more knowlegable fellows here might be able to elaborate

[jhonnieblue]

Nope never had any issue with it

[whiteknight1431]

Thanks for the feedback Supra GT- Four and jhonnieblue, why I asked is that I parked up on my lawn and rain fell just enough to dampen the grass and it was pain to get out of there 4H,4LO wasn't enough and mind you the driveway was 3 feet away, the tires wasn't all terrains but was new highway Maxxis 770. I had to take my flat Rav to pull me out.*Shame face*

[jhonnieblue]

And that's ure prob right there..those HT have literally no grip for wet lawn.. Had the same prob with my continental HT...wanna put SOE Firestone destination AT on it soon

[whiteknight1431]

Ok cool thanks for the info

I not having any issues with blowback or back pressure, and I'm running 116,345km on my navara now.

Had the water pump changed last month (was seeing a slow leak of coolant coming below the pump, was determined that the seal was going bad and coolant was coming out the safety valve)... and in the process of changing the pump the boost hose from the compressor side of the turbo to the intercooler had to be removed.

Later on during the weekend i noticed a small oil leak from the boost hoses, figured I should check the intercooler one time to see if any oil was getting in there - and it was dry inside.

So nope, not getting any blow back issues, no need for a catch can just yet.


U can have ur nav checked at the firm if you like for boost leaks, other than checking and making sure every fitting/clamp/boost sensor is well tightened.

All navara's (D40 series) are open diff in both front and rear.

Yup, what he said ^^^

were you on an incline?
Can happen with any open diff vehicle, don't feel ashamed.

What you could have done also if there was no other vehicle around to assist was drop your tire air pressures down until you can visually see them getting soft - then flip the little dial into 4LO and use 1st gear to crawl out (no throttle at all, just crawl). Then flip back into normal 2H and go air them back up at the nearest gas station.

Or just chuck a piece of plank wood under the tires and come right out.

And that's ure prob right there..those HT have literally no grip for wet lawn.. Had the same prob with my continental HT...wanna put SOE Firestone destination AT on it soon

Those tires are better as H/T than A/T.

Thanks for the great feedback @lighthammer .

[lighthammer]

No problem dude - can't tell you how many times my own navara get hung up on trails cuz of the open diffs. And i've had the "wet grass effect" happen to me too, when I went offroading for the very first time with my nav (it was 3 weeks old, hadn't made the first payment yet, and was stuck on a slippery mountain side with a 40-foot drop on a narrow precipice).

No worries buddy, you're not alone in the open-diff club.

[Captain Awesome]

Open diff also applies to the 4x4 d22? Also where except Massy can one go to check if a boost leak exists?

[gready123456]

FYI Please speed balance every 20-30k My van is at 100k since i got it from the firm i never did a speed balance i started to hear noises which sounds like my tyre pressure was low ( a flap noise on each rotation for the tyre)i told N&M they aligned and had the same problem soon after i had a falling out with NM and never took my van back, at 35k i changed tires the noise stopped ( firestone destinations) after about 60ks on the tyre i started to hear the noise again i aligned but that did not help , i pressured up my tires , rotated still not change , i took it to my mechanic and he said it could be bearings but wait and see if it is getting worst before buying a new one . The noise started to get worst and i noticed the tyre was cutting badly . i took the can to rotate tires the shop did a speed balance on the tires GUESS WHAT NOISE IS GONE .. hope this helps ...

And as for squeaking noise its the bonnet latch u need to grease that regularly well more like pack it with grease

[Aaron 2NR]

u kidding right?? i supposed to balance at rotate at every service.....i personally balance rotate and align every 5,000km....you never felt your steering shimming etc?

No shimming just noise

Need some advice with regards to maintenance. I am no longer servicing at Neal and Massy. My mechanic who works at Neal and Massy (south) recommended using Castrol Hypuron as he will be doing my oil change as per Neal and Massys 5000km schedule and it obviously will not make sense using a full synthetic oil and changing it every 5000km. What I would like to find out is, which will be better; sticking to his recommendation or switching to an Amsoil or Royal Purple and doing my service every 7k-10k km? I use my Nav mainly for picking up and delivering material for my business (rarely anything heavy) and mostly highway runs.

[Aaron 2NR]

at the cost of liqui moly full synthetic, you can change at 5 or 10.

5Q cost $350 full synthetic...i've changed our entire fleet to moly.

Thanks Aaron. Will check out the link.

[whiteknight1431]

Any of you guys ever did a remap? Saw a guy on tuner offering the services for the D40 navs.
