Nissan had designed an intentional slit (left arrow) where the manifolds mount to the exhaust ports on the block. The thought is, whether right or wrong, that allowed the weight of the cats to eventually cause a crack (right arrow). The cracks don't always occur where this one did. Mine was further towards the cat itself, but this one is a classic example. Yeah, the aftermarket headers fair much better, but it can be an issue to get safety and smog inspections in certain areas when you put headers on because you are removing the pre-cats. Supposedly Nissan redesigned the exhaust manifolds due to this issue, but I don't know what year that took effect.I've been reading a lot here so what's the reason why the manifolds crack? It's a shame Nissan just replaces with OEM and they still happen.. It seems the aftermarket headers fair better? Anything to look out for on the drivetrain?
Just the opposite. JBA headers with long tubes install removes 2 of the 4 OEM cats.If the aftermarket has cats it should be less of an issue as far to pass emissions.
What are the symptoms of this? Looking at a QX56, it has an ever so slight vibration, I think it's tires, the truck has been sitting for a while. The likelihood is that they're flat-spotted, but just want to cover my bases.Here are a few common things i would watch out for and their approximate part cost (labor not included)
1. Exhaust Manifold leak ($250 per side)
2. Seized Rear Camber bolts, which means all new Rear Lower Control Arms, Spring Buckets and hardware (Parts: about $550)
3. Rear Air Shocks leaking($225) (if so equipped). Also make sure the air compressor works ($210)
4. ICC laser for adaptive cruise control goes bad alot (if so equipped) (used $150 to $650 and New $1300)
5. General Electric issues
6. Make sure front differential is in working order and doesn't make any noise or vibrations. (used $500 and New $1200)
7. Inoperative gauges in cluster can be fixed for about ($150)
8. Loud Clicking from HAVAC Actuator ($35 per actuator)
I am sure there is more, but I cant think of them
leaks, clicking noise under acceleration, and any other vibrations/noise it may cause.What are the symptoms of this?

I went from GMC Envoy XL to Nissan Armada... bought my 05 Armada in 2015 with only 60,000 mi and 1 previous owner. It now has almost 150,000 mi and never had major issue. She's a beast! I'm in process of upgrading the navigation, stereo/DVD system and just purchased beefier nittos and wheels for her!Hey Guys,
Finally wising up and getting away from Domestic crap. I already have 2 Nissan's in the family and I'm looking to add a third. I've been doing lots of reading and a couple of warning signs seem to stem from bad Radiators and Head Gaskets over a certain mileage. Are there any warning signs as I look at older Armadas. I'm looking at higher mileage ones as my budget doesn't permit much more looking to Spend $10-$13K here in Canada and there have been lots around with 140000 Km - 190000 Km.
Are there any warning bells or anything I should be worried about with these rigs. Just finally getting tired of driving a money pit GMC.
Thanks in Advance,.
I literally was in your shoes and am a new owner of an Armada 4x4. Almost everything you have shared I was is the same boat. You left out the Pathfinder 2008-2012 4x4 w/V8 and the Lexus GX460/470. The Lexus is an amazing rig but they are costly.Looking for input on the Armada and those years in the title. I was looking to get a family hauler and Titan Crew Cab was also on my list as well in the same year range. I like the look of the Armada and it seems roomy. I would consider towing with it as well. I am aware it is not the best on gas. I'm coming from a Jeep Wrangler TJ and they are not gas savers. I would like to find a 4x4 but likely will end up with a 4x2. I have not driven one yet, I have driven and like the Sequoia but they are a lot more money. Also, Tahoe's/Yukon are also on the pricey side as well. The Expedition if I could find one with the 5.0L, but these seem to have terrible resale value. Can anyone share info on these SUV's?
If you're looking at Salvage/Rebuilt or a vehicle that shows a lot of issues it will boil down to knowing you are going to be faced with repair costs. I dont see that being cheap. Why not up the budget and find a better Armada?The car has 175k looks like the normal header issue plus the exhaust resonator near the transfer case? Has a good decent leak so it’s loud on throttle.. the only thing is rust.. passenger rear wheel arch but driver inside door in the lower panel a small hole.
the undercarriage is a little rough on rust.. I’m not sure he’s asking $2400 the 4wd light and slip, vdc and ses lights were on looked at the coolant it was green sniffed no gas smell.
the other I was looking at same mileage but it has a rebuilt title which I’m not sure if that’s a good or bad thing..
Potential New Owner--what to look out for?
Hello all, I just joined. Have never owned a Nissan before. Looking for a 10 - 14 low-miles 4WD Armada. Just wondering if there is anything I should be aware of in regards to differences in year models, for example a 4WD problem in the 2009 model that was corrected in later models. Are there 4WD models and AWD models out there or just 4Wd. ?
