Just noticed that my boot is ripped a little on my top ball joint after having springs and shocks done. Ball joint is almost new and has no issues at the moment. Is there a sealant I can use on the boot to hold the grease in? I can go back and complain but don't think it will result in the install of a new ball joint.
Trying to degrease the rubber and have sealant stick well is likely going to be a contest of futility. There are "replacement boots", but I would be contacting the shop and seeing if they will the work or replace the ball joint. I would go as far as paying for the parts and having them do the labor since they damaged it. But, all that said, if the rip is small enough, just keep an eye on it, and keep it greased and wipe off the excess. It really is not a problem unless it is washed out, and that takes quite a bit of heavy driving in a good bit of water. Many people over-grease and blow them out anyway and drive them for many years on daily driven cars.
