Hi there guys, just started noticing since couple of days. when i hit the gas real slow i can hear a knocking noise, but when i put the car in neutral and hit the gas no noise. if i drive less then 10 mph i can hear it constant, does not disappear.

if anyone got any strangest idea what this could be before the Pep boys #%#$ me tomorrow let me know

thanks in advance

 

any advice, any thoughts

thank u

 

like engine lifter noise? you need to be a bit more descriptive with "knocking."

Is consistent with engine RPMs, or is it something constant.. possibly to do with your suspension or drivetrain?

 

it is consistent with engine rpm's i hear it when less than 10mph. the noise only comes up in slow speed. but if i keep my car going at 10mph i'll hear it, "khat, khat, khat, khat" i wish i could describe the exact sound.

 

In other words you hear the knock only when the wheels are rotating correct?

 

I too have a knocking sound while i drive, sounds metallic b/w 3K - 4K rpms. any ideas?

 

Knock/ping/detonation
Screwed fuel.

 

is this sound coming from the engine or from the wheels??? I have approx. the same knocking but it's coming from my rear brake pads (I didn't replaced the little springs that holds them) so it sounds like this at low speed..

 

Try premium gas if you're not already using it, an octane booster, seafoam and/or chevron Techron additive.

 

thanks guys found the problem, i think so. took it to Midas once the car was lifted, both of my axle's were torn or broken right where they connect to the tire. the rubber covering was broken. i am going to get it replaced tomorrow for $313 at Pepboys. or $1000 at Nissan dealership

 

Or 180$ (AZ 75$ per side) 30$ labor, or DIY for 150$

 

To bad i don't know any good Nissan Mechanic's in the Los angeles side.

 

You don't need to be a "Nissan" mechanic ... I take mine to my local alignment shop when I'm feeling lazy and my finacial situation is permitting. .. try it on your own too, it's not that bad ...
