I have a leak in the transmission / axle seal on the left side and a torn CV boot on the outer right. Should I just replace the axles while I have them off? She has 100,000 miles but I have no known problem that I know of. Advance Auto has them for $55 bucks each looks like a GSP brand ?

My guess would be that your original axles are a lot better than the GSP brand.

If you clean them off and they're in good shape, regrease and re-use. The OEM axles are 10X better than the aftermarket crap available right now.

Thanks guys . I'll just replace the CV boot and leave the axles . About the first thing I have been able to not replace.
