I have had a 2004 Blazer Bay 2170. I have had leaks develop on the rear hydraulic steering cylinder and have replaced the cylinder 4 times now. The manufacturer (Teleflex) has been great and has replaced the cylinder under warranty each time. They are baffled as to why I keep having this problem. Apparently something is putting stress on the steering cylinder which damages the packing gland and causes it to leak. I wondered if any other Blazer owners were having this problem and if so, what was the fix?
