Have custom 02' Sentra. Every time I shift gears, doesn't matter if i'm drag racing or not, I always hear a jarring noise like something is grinding. A fellow race told me that it could be a the axle assembly. Here is a picture and description of that Nissan Parts. How do I repair this? I would like to know before I call a mechanic and actually pay for all his services. Any ideas?

 

i also have a 02 nissan sentra and i was just wondering how many miles you have on the car. by the way i have a stereo box that will fit perfect in your trunk and i am selling it for 300-350 .
