Default Bearings???

How can you tell when they need to be changed? What mileage would you guys recommend? Any vid clips if it make a noise?

I had to change my first set at around 80 k. My second set is already starting to making noise at 105k. I only auto crossed on them 3 times with the new bearings.

I even put in a set of axle shafts cause they were scored. Im hoping the shafts aren't scored again.


Did u do yours yet?

A better question would be... what sounds or symptoms does your car have?

I've seen new bearings murdered in one hard launch at the drag strip. I've seen other 10-bolts last as much at 200k because it was primarily highway driven. I see in your sig you have the diff cover, that's a big plus, but it really depends on how you've driven your car. If you can rebuilt it yourself, NAPA makes a good kit (stay away from the eBay specials or discount part stores) for around $125 with everything you need. GL.

Mine make a slight sand paper type sound u hear when driving slow 20-40km/h and the windows up with no tunes. U also might hear a hum on the highway if it's quiet in the cabin. I even noticed u could make it hum when cornering on an on ramp when my first set went.

Forgot the best check is lifting the car up and checking the wheel for play.

I can tell you that even 50k rear ends have a pretty good amount of slack in them when taken apart. After 100k it tends to get real sloppy.
