Hmmm. I had great success making new emergency brake dust boots out of some rubber nipples. I wonder if we could find some really big ones to do a steering rack with?

Rubber nipples and a nice rack? Link?

I don't think your problem is the bellows itself. I'm not familiar with our rack design, but there must be a way to balance the pressure between the bellows. One design is to have a hole in the rack bar itself. Again, no idea how this is achieved on our cars I've never had one apart. This hole allows air to travel from one bellow to the other bellow. If the air has no place to go it will expand and contract the sealed bellow and it will fail. My guess is this hole is plugged. Depending on where the hole is, it may be possible to clean it out. I would have them install the bellows then turn the rack full turn quickly and if you see one collapse and one inflate there is your problem. I bet if you put a small hole in the bellow they won't crack anymore, but defeats the purpose of the bellow.

This is good thinking. Maybe it's not a leak but a rub against another suspension part?

My experience they can fail by rubbing against something, or just from fatigue from collapsing and then blowing up like a balloon. Based on the failed photos it looks like the one for sure was inflating and rubbing against the LCA.

Anyway, worth a look.

I finally stumbled across a rubber below, Duralast FA0833, I'll see if that helps. For some reason I don't recall seeing the latest responses above. I'll ask the shop to watch for the ballooning of the new bellows after installation.
