well, not 1000 miles since I've replaced the hydroboost due to a leaky seal, the new "rebuilt" booster blew itself up. The part on the side of the hydroboost ripped itself out of the threads. Shot power steering fluid EVERYWHERe. I had no steering assist. Terrible. Went to autozone to get yet another replacement, will take about 5 days. /forums/images/graemlins/frown.gif Anyone know if I can replace the main seal behind the spring?
