I have a 1999 Chevrolet Blazer and it squeaks when driving and it is very annoying any help would be appreciated!!!!

 

squeaks can be hard to locate, especially over the internet

What I've done in the past is to get someone else to drive on a non-busy road while I try to find the source. When you don't have to worry about keeping your eyes on the road, you can move around and listen better. I'll even crawl in the back (the wayback as my kids call it) and see if it's coming from there.

If you find the general location, but can't find the source, post your findings and maybe we can offer some suggestions.

 

lube or replace whatevers squeaking.
