Re: front struts squeak and creak?

Anyone think it could be the added friction from the increased viscosity of the rust proofing spray? The sound became noticeable almost immediately (day or two later) after the truck was in to be rust proofed. If so, wondering if a liberal dousing of a light weight oil like WD-40 or equivalent lube ...

front struts squeak and creak?

Recently had a rust proofing and underbody spray service performed on my R51. It seems ever since then the vehicle has squeaked and creaked constantly. It sounds like a hoop ride going through the bank teller lane. I had it looked at by a shop. They said it appears to be stemming from the front stru...

Headlight upgrade compendium

Have been searching for a quality HID upgrade for a 2011 V8 R51. The below are a compendium of posts discussing this topic spanning pre- (2005-07) and post-facelift (2008-13) R51s posted over the last 2-3 years. From what I gather there is no easy upgrade for post-facelift R51s. It appears true HID ...

Check out these videos. There's a little worm gear that can come loose and fail to actuate the heater control valve. You can place your hands on the coolant hoses on each side of the valve for an indication if it is failing. Seems to be a pretty common problem on the 5.6L https://www.youtube.com/wat...

Was kicking around the idea of doing electric cutouts pre-cat so I could have quiet factory sound during normal driving then balls to the wall on demand... but have heard that will result in throwing a code. Running a cutout after the cat/resonator seems like a waste since only eliminating one restr...

Local shop pressure tested the system. Couldn't find anything. Haven't seen any blue fluid under the truck other than those two times. Freaking mystery. Go figure.

Windshield washer solvent is sometimes blue. And that's what it looks like to me, but I can't think of a reason why solvent would spill over. Now on the other hand it does make sense that coolant would spill over on occasion due to being pressurized (hot). I just can't see where it's coming from. An...

Coolent (or washer solvent) puddling under truck?

The last two days I have noticed blue fluid puddling under the vehicle when I park it in the garage. I am unable to identify the source since the engine is hot the fluid evaporates and I can't trace where it is coming from. It does appear to be dripping from the engine (V8 engine) oil pan but that c...

As others have said CAIs can potentially work, with most of the benefit coming from it augmenting other mods (headers, exhaust, intake manifold, etc.). In my experience the air intake on the pathfinder is pretty good in that it actually ports to the fender cavity, doesn't have a ton of restrictive b...

Had favorable weather and a few spare hours this morning so tackled the spark plug change. Local AutoZone suggested NGK Iridium IX (LFR5AIX-11). A side-by-side comparison with the old plugs yielded they were a very close match to stock fitment. Lucked out and stumbled into a $2/plug rebate turning a...

Stick with the OE spark plugs, NGK # 93759. It's coil on plug, so there are no wires to replace. There is no fuel filter to replace (it's part of the fuel pump module in the tank). That leaves the engine air filter and cabin air filter and coolant. For the coolant, Pentosin makes the "genuine Nissa...

Time for tune-up. Tips?

The odometer on the V8 R51 is approaching the point where a tune-up is recommended by the factory. Curious if anyone has any hacks that make the job easier to do and any recommendations on plugs/wires, etc.
