front lower control arm bolts breaking

[MUSKOKA800]

My sedan was well out of warranty when one of mine broke in my driveway. Dealer quoted over CA$700 to perform the fix. I bought two of the upgraded bolts at the parts counter for about $6 each and had an independent shop replace them for one hours labour. He used an air chisel to easily back out the broken headed bolt and gently ratcheted the other out. Total cost of update about CA$100.00. Aside from maintenance, which I do myself, this is the only repair money spent on this car which runs like a charm despite all the performance and handling upgrades. 7 3/4 years and ~170,000 kilometers. Can't complain about that.
At the time a long thread was running about the issue. I advised others who hadn't yet experienced the breakage to spend for the two bolts and replace the original troublemakers. It would be 10 minutes under the car to switch them out, before the heads pop off.
