I have the above 2011 J32 Maxima 250ST L2 which has only done 58,000km and about a year ago it developed a noise in the front (suspension?) area when the weight moves forward or over bumps. This started after driving over a rough unsealed road. I brought the car from new when I lived Sydney, Australia and I brought to New Zealand when I returned in 2013.
I've taken it to 3 different mechanics and had many things checked including sway bar bushes, links, mounts fitted. New left inner steering rack.
But still the noise is there.
I saw in a recent thread that the there was a Nissan recall for 2009 to 2010 Maxima's to replace front strut mounting insulators which may crack. However my car is a 2011 model, but could this be the source of my noise?
I am exhausted trying to solve what the noise is and the mechanics I've taken it to say keep driving it until the noise becomes so bad that it will be easy to identify, but hopefully someone on this forum can tell me what the problem is or how to better isolate where the noise is coming from?
