Alright though it isn't a GA it is my winter truck for now. I have this Blazer and everytime that I throw it in 4WD and get going, there is a loud whining sound then when I try to shift it back into 2WD it takes a min. It gets up to around 35 mph then a clunk and it shifts into 2WD. I am thinking and hoping that it is just low fluid so does anyone on here have a how to or know how to check the fluid in the front differencial (sp?)?? Also any other ideas are welcomed.

Thanks

No I don't change it while I am moving. Although you can (not at high speeds) I change it while stopped and it takes a moment to actually change.

In my roommates Explorer, it takes a second or two when you put it into gear before it clunks into 4WD low. He said it's been like that forever, seems fairly normal to me.

What year is the Blazer? I know someone with a '97 or '98 who had a similar problem, turned out to be a wiring issue. The wires were frayed or corroded, something like that.

It is a 96 Blazer. I just got done checking the front differential fluid and had to add some. Some what fixed the problem, but there is still the noise. 02 do you happen to know where the wiring problem was at?

Also when ur stopped putting into 4wd or 2wd, Do u have it in park? Buddy of mine has a Dodge ram and he has to stop to change, like u are doing, but it also as to be in park? Other then that, im not sure what to tell ya. They do make all sorts of noise changing back and forth in any 4wd Truck i have ever been in.

2wd to 4wd high, you should be able to do on the fly ~25mph. 4wd low can only be engaged and disengaged when you are stoped with the transmission in neutral. whats the fluid level in the transfer case? has it ever been changed?
