Last night when I was driving my car home I noticed a popping noise which appeared to be coming out of the front right tire. My passenger said it sounded like the rear of the car... It was hard to tell where it was coming from but I drove extremely slow in case it was a wheel.

I tried to move every lug nut but all seemed to be tight. What the heck could be up? Differential fluid needs changing? Axle problem?

I have changed my Spark Plugs and Belts myself within the past 2 weeks. I did not torque the spark plugs by the exact standards on the board (didn't see them until afterwards), I just torqued them down tight, does it matter that much?

Thanks!!

 

Passenger side rear axle clicking? Does it only happen when you're moving slow from a stop?

 

It happens at random times when I'm driving. It's not very loud of bad, just sounds like a clicking or popping... I read the TSB on 2003 350z's "Cluncking noise coming from front wheel" .. do you think this could be it?
