So, to break this down:
When air gets into the power steering fluid due to the poor design of the reservoir and/or a leak in the system. The bearings in the power steering pump build-up heat and thus fail.
Are there after market power steering pumps available which are built better than the factory pumps, that are not susceptible to this over heating?
I see a lot of people trying to increase fluid amounts, reduce the fluid temps and reduce the amount of air in the fluid system. Why not make a better pump? Sorry if this has already been discussed, just thinking out loud.
FYI, I noticed a leak in my system at Havoc, it's on my to do list.
