While I replaced the tensioners, last week i snapped a bunch of pics. When i was searching on the forum i couldn't find much info other than the problem and the fix so here are some photos. Took me about 16 hours, i broke it up in a few days over christmas vaca, and did it in my garage which isnt the ideal location because if the size. Didn't need anything spec. just the basic tools, even though i have pretty much every tool!! Very involved, you have to take, lots apart, including the front cam journals which are ontop of the tensioners, valve covers, alt, ac, all belts, intake plenum, bunch of wiring harnesses, Parts were about 300.00 with all fluids, and thats 20% off on nissan parts. Hope these help.
I meant to mention, see how far worn down the plastic blocks are compared to the new ones. See how there wasn't any plastic left and the timing chains were just metal to metal, when they start to make noise, this is when the chain comes in contact with the metal, so it need to be taken care of asap. The chains start to kink, and not flex like they should, my chains were smoked fom riding on the metal button on the tensiners. My truck is a 2005 with 66,000 miles.

Great job on the work and the pictures. I just bought a 2007 Frontier and found out about this problem and want to learn everything I can about it.
Do you know if the replacement guides have been improved or will you be doing this again? Also, is this a problem on certain model years or are we all going to deal with this sooner or later. What I've read leads me to believe we will all have this problem at some time. I can't believe Nissan left everyone holding the bag on such an obvious problem, I guess all car makers are the same when it comes down to it!
Anyway, how did the repair turn out is everthing quiet? Again, great job and thanks for the pictures. It makes the problem easier to understand we I can see it.
From what i understand 05-07 have this problem, and yes they say that the parts are updated and they do have different part numbers on the box....the bad news is they look the same, couldn't see any different plastic material or anything that will make them last longer..but we will see. It was loud, sounding like a supercharged one, and now its very quiet, cant even hear it idle. While i was in there, i replaced, the thermastate, idler wheel, idle tensiner too and belt, all of which are known problems with these years. I just bought the truck 3 weeks ago and knew the problem when i bought it, so dont know how the truck was treated before me, but the inside of engine was spotless, very clean. I am running syn. oil now to help with the friction on the tensioners.

The tensioner, belt problem sucked big time for me too on my 05. Luckily I was able to resolve it under warranty after numerous trips to the dealer.

Would this be a common problem for the Gen 2 4-cyl? I know the engine layout has to be drastically different from the 6-cyl, but maybe they use the same tensioner, maybe they don't even have a timing chain, etc? I've never looked into this before, but I am curious now.
