Question about 2005 Nissan Murano

Nissan murano rattling noise front

I own an 05 Murano that rattles upon acceleration, between 1500 - 2000 rpm; the rattle is NOT consistent. When the car is in park and the accelerator is pushed, it does not rattle. When we put on the ebrake, and applied the regular brake, put the car in gear and pushed the accelerator it also does not make the noise. After taking it to a quiet road where stops and starts can be made safely, we determined that it rattles upon acceleration with more consistency in first gear. We have had the heat shields checked out and they are fine. We had the oil and other fluids checked as well and the report came back fine on those as well. We also changed the octane for the gas (going higher) and the rattle is still there. The Murano has 87k miles on it, and aside from this rattle when accelerating, it runs great. What else should we be checking on the vehicle to get rid of the rattle noise that it is making?

1st check eng, oil cooler oring leak, 2nd right /rear exh. manifold crack(look up at manifold for a crack, view it from under near the oil pan area) 3rd remove lower oil pan to look for small piece of plastic guide -if you suspect timing chain, and check b1,b2 intake valve timing less than 3 degree difference and scope test cam sensor trace pattern to see if chain is loose(not commen) 4th pull out intake valve plate (3 bolts)to see if screws missing(not typical) any codes?

    There are no engine (or related) lights on and it has not thrown any codes. I will check out the other things you mentioned and update if we found anything, or managed to fix it. Thank you for replying!

Nissan had a problem with the exhaust bracket being cracked or broken

    If the bracket was cracked or broken, would the rattle be consistent, or would it be variable? It seems to be that once I pass over 20mph the noise goes away. The rattle will also go away if I take my foot off the accelerator, and sometimes will start again when I put my foot back - but not always (which I regret not mentioning in my original post). I will look into the bracket though, thank you for replying. :)

SOURCE: 2005 nissan murano sl, with rattling sound when accelerating

I recently experienced the same symptom with my '05 Murano and it was not a fuel problem. The dealer listed the cause as dry axle splines and replaced both front drive shaft assy's. Note that this was done as warranty with no cost incurred by me.

04 murano right side engine rattle


Hello windy....There are a few thing on the murano that could cause this... one is the exhaust gussets that go to the bottom of the oil pan to the exhaust, they can crack and cause a rattling noise. Also I have seen the rear exhaust heat shield spot welds come loose and cause a rattling noise, from exhaust manifold down pipe on the cat. converter. I would check them first, also the park brake cable will lose tension and rattle on the undercarriage.
A more serious problem would be the timing chain and/or chain tensioners...these are known to make noise around 50-60k. The tensioners are operated from oil pressure, the face gets worn, the chain stretches and it results in a rattle or a slapping noise
Useing a full synthetic oil with regular maintaince will help prevent premature wear.
Good luck, i hope this helps..please rate me a fixya.
