Hfx_Cdn said:Gary, to support your comments, I recently realized that i was getting up there in milage on my Durango, so I have booked to have them replaced. It is a 6 cylinder, so I was very surprised to be told that the time allocation is 2 and a half hours labour. Given that estimate, I would not even try doing it myself because using Rene's time examples, it would take me a couple of months to change them.
