there is a quick temporary fix for the squeaky leafspring, try finding po lithium grease and spray it in between the leaf of each spring it has a straw like the wd40 for hard to reach areas... hope this helps... ^_^
another solution maybe is to tighten the U-bolt that holds the leafspring... peace po... ^_^

I wish someone with a 4JJ1-equipped D-Max would have a BOV installed on his ride. That I want to see...

kuya, if you can post the top view of your 4jj1 and the pipes that connect the intercooler, turbo, engine, and the turbo wastegate, i might be able to show you how to put the bov... ^_^ peace po....

Hehe. Mine is also a 4JH1 like yours. I was just wondering how much more "oomph" could be extracted from a 4JJ1 engine.

*8800621,

baka nasa iyo pa yung instruction manual mo ng BOV installation, paki scan mo naman at i-upload...i just have some diy plans in mind.

Thanks sir, I would definitely try those.

Does anyone know what causes the brakes to pulsate? It's like sitting on an office chair with wheels with someone pushing you forward, then back, then forward, then back. Any advice would be appreciated.

Perhaps your ABS is working. That's why vehicles equipped with ABS, the brake pedal should not be pumped as it lessens its effectiveness. Instead, just press the brake pedal and let the ABS do the pumping.

Sir/s, with the engine specifications of 08 Dmax, do you think it could match the speeds of its competitors in terms of speed, same 4x2 category but regardless if it's M/T or A/T? Let's say in NLEX, end to end. I noticed that in terms of HP, the Dmax tops in that category but with the 294 nm of torque compared to 314(Strada), 330(Ford) and the 356(Navara), it clearly says it's the weakest in that segment. Their HPs are not that far so I think if I see one of those vehicles on the road and try to feel a little adrenalin rush, I might eat their dust.hehe Though I know pickups are not meant for racing, sometimes I wanna give the engine a little exercise.hehe

*kikoy: that thing krrrrggg somtimes happens to my 08dmax also sounds like may sumasabit na goma it somtimes happens during very low speeds. pero minsan totally wala. parang may pumipitik i'll try to ask my s.a. kung ano reason nun will give feed back after sched na kasi ng p.m.s. ng max ko.

Yup, it's quite intimidating at first, especially coming from a sedan, to drive a truck. Everything is different from it's height to it's ride. But give it 2 weeks and you'll feel that you're getting the hang of it and you'll soon prefer to drive it than a sedan.

For your query on the spray on bedliner, I haven't tried the plastic bedliner yet so I don't know how durable it is. All I know is based from my friends, they didn't recommend that to me. They told me that in time, water might penetrate in it and it will cause the bed to rust. I have always used spray on bedliner on my trucks and I could say that they are really durable. They might be more expensive, but it's worth it. Added to that, though I already have a spray on bedliner, I still put the rubberized padding (I don't know how to call it but in Banawe, I see men carrying those in rolls and they cost 450.) I put that for added protection so that when I put a thing that has sharp edge, it wouldn't scrape the liner.

Sir, could you please observe your rig if this also happens to you. Before at around 1300-1600 kms in my odometer, I noticed that my truck makes this sound from the engine. A quick but weird sound that has an echo. It sounds like this kkkrrrrrrrraaaaaaarrrrrrrrr (I'm sorry for the sound effects.hehe) I don't know how to mimic it but it's like that. Usually it's duration is about 2 seconds but the echo elongates it. I tried to have it checked in my dealer, but I don't know how to explain it and I don't have any idea where it's coming from and when it will make that sound. I went to Vigan last weekend and traveled like 900+ kms but it didn't sound and today while parking it, it made that sound(my odo reading now is almost 2300.) It's so odd. If this happens to you, could you please let me know. Thanks!

Sir, as your query for the sound.umm, i havnt noticed anything strange pa naman with the sounds of above 1600rpm. mine still sounds the same as it was when i got it out from the dealer. i seldom use my radio so as to hear the engine if there are any problems. but luckily, nothing. i just went back to the dealer to have my camber and alignment checked coz i have a stiff right turn. or may kabig pa sa right.but after that, still nothing with the engine.

ill inform you asap as soon as i hear anything strange too. thanks

*Denver Max: Sir, I guess you're the 3rd 08 Dmax owner who experienced it. We have exactly the same experience. The thing is nothing happens to the car when it sounds and as for me, it only happens once in a day and I don't have any idea when it will sound. We're looking forward to what your SA will tell since my SA was no help coz I couldn't exactly pinpoint where the sound is coming from and it didn't sound when I had it serviced. The car already traveled more or less 170 kms of city driving since the last time it sounded and so far I haven't heard it since.

*rasta: Good for you, sir, that sound didn't occur. As for me, my truck has been with me for almost 1 month now and it has traveled more than 2500 kms, so far I don't have any problems with it. Just a few but tolerable squeaking sounds in the leafspring, other than that, it's all good. I also had my wheel aligned in my 1st PMS since mine was also pulling to the right.

hi guys...

Finally, I got my most awaited Tornado Red Dmax last 08-28-2008. I hope it will bring some luck.
I just have noticed the following; I am hoping na mabigyan nyo po ako ng inputs.
1. I tried to drive it below 70 kmph. May slight na kabig sa kanan pag smooth ang road. Is it normal? first time ko kasi magka pick up. Yung starex ko hindi naman ganito.
2. i noticed na hindi lahat ng Bolts sa Fronts Seats ay may plastic cover. Ganun ba talaga to?
3. Yung indicator dun sa meter hindi mag light kahit open yung doors.

I will ask my dealer next week , at least magkarun ako ng idea before informing them.

By the way, bago ko kinuha to, pinakabitan ko ng turbo timer sa casa. I hope this will help .

Thanks

[wildthing]

1, 2, & 3 - ibalik mo sa casa for reklamo. merun plastic na cover lahat ng bolts ang 2004 model ko (so no reason na wala ang 2008 model). yung kabig means hindi aligned... unless magkaiba ang inflation ng tire mo sa front or tabingi ang road na pinagtestingan mo.

my 2004 doesn't have those door light indicators sa dash...so i don't know... but better ask the casa.

Sir, we have the same color but I bought it last August 31, 2008. Who is your dealer? Mine is Isuzu Q. Ave. As for your questions:

For the pulling to the right issue, I experienced that with mine too. I just had the wheel aligned during my 1st PMS. But before bringing it to your dealer, maybe check your tire pressure first since maybe it's the one causing it.

Could you please tell me what are "Bolts sa Front Seats"?

Our Dmax doesn't have that door indicator light. What I do is I put the light on the ceiling to "Door" just for me to know if a door is open.

Awesome sound, heheh.

Perhaps your ABS is working. That's why vehicles equipped with ABS, the brake pedal should not be pumped as it lessens its effectiveness. Instead, just press the brake pedal and let the ABS do the pumping.

Thanks sir rna800, but I don't have ABS, mine's only a 2005 LX A/T. My SA said it could be uneven brake shoes. They tried to sand them down and the pulsation became less noticeable, but after a couple thousand kms it's back. I don't pump the brake pedal either, I just operate it as I would any car. Could it be the tires? I'm considering changing them, I find the stock tires slippery on asphalt specially when it rains.

I heard a strange sound in my max too, turns out it was only the engine cover that came loose. One of the bolts wasn't fastened properly by the people who detailed the engine. Tsk tsk.

On paper the Navara should beat out all other 4x2's in straight line acceleration and top speed. Like the Ranger it has 5 speed A/T, but the most torque and the narrowest tires (205 vs 245 for all the rest). It's also closer to the ground. It should be fun to race with other pickups though. Haven't had the chance to try this yet.

[wildthing]

as i would have seen it (navara) in action, sa high RPM lang mo siya makikitang mabilis. it went pass me while running 160kph... so probably it can do as high as 180kph. dmax is rpm was near 4K during that time.

pero tingin ko (opinion ko lang) parang hindi siya as stable as the dmax at high speed...probably because of the narrow wheels?!?

[rna800]

I would like to correct myself in my last post. I got my unit last July 31 and not Aug. 31. For the sound that I mentioned prior, I thought it's already gone, but I was wrong. It sounded 2x today, after more than a week of not sounding! Anyways...


*Wh1stl3r: Sir, as much as I would like to help you, I am sorry to say that I am not mechanically gifted.hehe But if you're in the QC area, I know a good auto shop that I could recommend. Or just wait until the gurus of this thread reply.

For the strange sound that you heard in your Dmax, how does that sound? I just don't know how to put it in writing but, with mine, it sounds like kkrrarrrrr with an echo. It's like a rubber or spring that gets loose.

Yup, sometimes it's fun to race with other pickups especially if the distance is not that far wherein just a little mistake with the gear and it could overtake you.


*wildthing: I saw in the Navara forum that an owner there has reached that speed and he felt that the truck could still give more, something like that. That is really a wow! I couldn't imagine running 180 kph while driving a truck.

Stability issue, I haven't ridden in a Navara so I don't have any idea. For Dmax, my fastest speed was 120 so I couldn't really tell if it's stable at high speeds.

Thanks Sirs rna800 & wildthing sa mga suggestions nyo. Di ko na siguro antayin na aabot ng 1500 kms.
By the way, dito po ako sa Cebu. I got my unit from Isuzu-Mandaue.
Actually, medyo confused ako kung ano dapat Tire Pressure. Nung kinuha ko kasi to sa Casa, sabi ng Staff dun ok na daw yung Tire pressure naka set * 30 psi (all tires ).
Nung dumating ako sa Bahay, nabasa ko sa Drivers door na 29psi dapat front and 41 psi back.
Mga sirs, ano po kaya ang ideal Tire pressure. Wala ako masyado karga sa back but sa loob ng cabin palagi may sakay.

Thanks po in advance..god bless

[Wh1stl3r]

*wildthing
I've driven a Navara a/t sir, lent to me by a friend. I think it can go well beyond 180kph if we're just talking about the engine and transmission. But you are right, driving at 180kph with those small tires is way too dangerous, it'll probably scare the pants off me. But then again, a tire change to a bigger size would be easy. Magugulo nga lang lahat ng speedo/odo readings. I'm not so sure if the suspension can handle that speed.

*rna800
The sound mine made was just like a busted shock absorber kalampag. I'm sorry I don't believe I've heard anything like you have in your unit. Does it happen when the truck is idling? Maybe if you could post the sound on you tube and paste the link here someone might recognize it.

Another weird thing comes to mind. Whenever I check the oil level of the engine the dipstick shows that it's always over the maximum level. My SA always tells me that this is ok, that the dmax oil level should always be this way. Is this true?

Also, could anyone recommend a good semi-synthetic engine oil? What grade do you use? Mine feels sluggish with what I currently use. I'd really appreciate it. Thanks.

[wildthing]

if you follow the doors, medyo matatag ang likod. i usually drop the rears by 2 psi (lalo na kung wala akong kargada) so that is 39 psi.

anything below that, magiging noticeable na ang uneven wear ng rear tires. (sa gitna hindi pudpod).... to prevent that, rotate the rear to front every 5K km.

sa 29psi sa front, tamang tama lang (IMO)...swabe ang play ng front.
