Rear axles
 

Going to be installing 4 10s soon and not sure if i should replace the axles as well. Is the ring/pinion/bearing kit enough??? Car has 55,000 miles

no need to replace the axles UNLESS you goto 31 spline ....otherwise the install bearing kit is all you need + fluid & friction modifer....

You don't need to replace the axles unless you want to upgrade; or your stock ones are bent like what happened to mine.

If you can aford it then go ahead and get the 31 and a new locker.If you plan on do some hard launches. Why you have it a part.
