Hi everyone,

Just bought a 96 blazer with 88K on in last weekend. Drove fine for about 1.5 hours on the way home then as I started to slow down it started whirring from the front passenger wheel area. As I came to a stop, at <5mph i could hear a ticking from the same area until I came to a complete stop. As I accelerated it did the same, out of curiousity I pushed the 4x4 button (oh yeah, since i didnt mention it has push button 4x4) it went completely away, pushed the 2hi button and it started up again. I pulled over and stopped. I continued to change it between 4hi and 2hi and could here from both sides something that souned like it was disengagin/engaging from the front end. After a few times of this I took off again and it went away. Today I had the same thing happen again, once again from the front passenger.

Any ideas? hub halfway locking in?

Thanks for any help.

 

Common problem. You either have a faulty vacuum switch on the transfer case, a partially sticking actuator cable (runs from the actuator under the battery to the front axle), or a problem inside the front differential. By far the most common is a faulty vacuum switch on the transfer case.

A quick search should come up with some good threads for your reading pleasure!

 

either that or it might be your solonoid for your transfer case is goin out cause mine was out when i bought it it costed 345 at the dealer

 

Thanks guys... that helped my searching alot didnt find much before... It does sound like the vaccum switch. I will have to give that a try.
