Ok i think my bearings are bad. I have a loud, very loud roar in my right wheel and its all i can think it would be. WEll i took it down and i found that whoever worked on that the last time on my car left the grease cap off and all the grease leaked out. The bearings looked ok so we just put more grease in and it still roars so i'm guessing they were bad. Just wondering if these are available at auto zone and also if it could possible be something else before i do all this work.

 

With the grease cap being left off I think it is the bearings. I would be surprised if parts stores didn't have the bearings. The part number on bearings is stamped on the inner piece (don't know its name) and they are usually easy to find replacements.

 

You can't just replace the bearing on the rear. You have to change the whole hub assembly. That is about $100/side through Nissan, but it's really easy to change.

 

ijust went to advance auto parts and they only sell the whole damn assembly. 119.99 Thats a load of sh%t. Why wont htey just sell thebearing?

 

Because the bearing is integrated into the hub assembly and can't be removed seperately. You can probably get them cheaper through Nissan.
