Hey guys,

I hate posting this on here, because I'm sure there is an explanation of it on the forum somewhere, I'm actually quite positive of it. I was having trouble getting the search function to work for me though, it was just taking it forever to do anything and kept kicking out to a page not found message after waiting so long.

It's a 2001 Blazer, and I've mentioned before about having a little 4x4 trouble with it, that was a long time ago though. I had some suggestions on what it might be causing it, and I have it narrowed down to being a vacuum problem. It's not always a problem, just on a rare occasion, and it does it just after the engine has been under a good load like just after climbing a good hill on the highway. The axles try to lock in it sounds like, and I had read that the vacuum can be what causes it.

So, what do I need to do with it?

I also appologize for putting this up again when I know it's one of those questions asked ten times a day.

vacuum actuator could be defective.

Do a search for 4x4, you should be able to find more indo on this.
