I recently bought a 99 V70 GLT. I was at the dealer with it while my wife was having her V70 serviced. I decided to let them look it over. The came back and said my ball joint boots were dry-rotted and could be replaced for 8. Seems to me I could replace the entire ball joint for that kind of money. My question is can I wait until I have to replace the entire ball joint or do these boots do something incredibly special that warrants a 608 dollar repair? thanks
