I should have known by the price, it was too good to be true! The originals were not leaking and were not making any noise. I only replaced them because the boots are badly cracked and I had the whole thing apart anyway. I have heard some people have not been able to stretch the boot enough to get them on. If I had the boots and the grease, I quess I could take them to a transmission shop to reboot them?
How hard a job is this and on average how long should the innards of the originals last?
