I have an old Honda Odyssey van with about 170K miles on it. A mechanic I trust told almost 3 years ago that one of the axles and struts were either broken or failing and could go "anytime". Chose not to fix it since I had planned on replacing the van. Thing is I haven't gotten around to replacing the van yet and I have driven 25K miles since then including 2 long distance trips.. How big a deal are those things? Worth replacing?
As you can see, I don't know much about cars/vans.
