Hi there. I have a 1997 Montero LS. I bought it in 2005. The crankshaft pulley bolt sheared off and I spent $700+ to have it fixed. It broke about 2 weeks later. I took it to a different shop and spent another $800 to have it fixed again. It broke again after 2 weeks. What could be causing the problem? I don't want to get rid of it, but can't afford to spend another $700+ on it. Please help.

 

Sounds like a ordering one from a dealer would have been a better route
