I have a 2000 echo which had a small tear in the driver's side cv boot. I took it to a shop, had it replaced (the boot) and now a year later the wheel on that side is starting to howl and there is grease leaking out the bottom of the boot. Is it possible that the boot was improperly installed ( the band wasn't tightened enough) resulting in the grease to leak out the bottom? Is it possible to repack the grease replacing the band on the bottom of the boot or is the cv joint ruined? It doesn't make any clicking noises nor does it bind.
