I have a 1997 Civic EX, the passenger side CV boot is torn, however it is not making any noise yet. It happend within the past 3,000 miles. The car has 113,000 miles on it, and most of them are city miles. Should I replace the boot or just replace the whole axle? How involved is it to replace the CV boot or whole axle? I am very good with cars, just have never messed around with suspension related parts very much. Thank you in advance.
