Is there any difference between the two axles? My 4wd blazer rear diff gears blew up and I have a 2wd blazer for parts and what not. Could I use the parts of the 2wd to fix my 4wd diff.

 

As long as the gear ratio is the same, it shouldn't be a problem. What year are the vehicles?

 

Both 2001

 

Check the RPO codes in the glove box. If they both have a GU6, no problem. GU6 is an open differential, and G80 is limited slip. Most GU6 axles are 3.42:1 and most of the G80's are 3.73:1 Gotta be the same ratio front and rear when you're done. If not, first time you use 4WD, you'll run over the transfer case with the rear wheels! Probably make big noise too

 

The 2wd Blazer axle is narrower than the 4wd Blazer axle by about 3". You can swap them but it will tuck your tires further under the body.

 

Hello. I'm looking for a 59-60 inch rear axle for my 51 chevy car. I believe the S10 4x4 fits this right. But does it matter if it's a Blazer instead of a Truck? I am getting conflicted reports. I want an 8.5 ring gear (not the 7.5) and a 3.42 ratio. Which S10 would work? I'd even prefer the drum brakes for the back.

Can you help me know what year, make and model I would need to search for? Some people say the 95 and newer. Others tell me the early 80s S10 and GMC 215. Others say the axles without the ZR2 can work but what you say here seems like it wouldn't. My biggest issue is making sure the axle is the right width and that is the hardest part to know for certain. I can find axles online that are S10 with 8.5/3.42 but I keep finding conflicting info that makes me wonder if it's really 60 inches.
FOR EXAMPLE: I am looking at a 99 4x4 Blazer (8.5/3.42) without the ZR2 option, and has disc brakes. Will this be the right width of about 60inches? When I punch in the VIN it says that the "track width" is 55.1
Does that mean the axle width (from brake plate to brake plate) is that? Or might it still be 59.5 inches wide? Does the 99 Blazer 4x4 have a 60" width?

I don't want to hassle with getting the wrong axle. Like I said, I can find them with the right ring gear and ratio, But I am not convinced that what I order will be the right width.

 

You might want to start a thread of your own, instead of digging up all these old ones.

 

Thanks. I'm new here.
I just started a new thread as you recommended.

 

No problem. I wasn't trying to be a jerk. But you'll probably get more and better info with your own thread.

And welcome to the forum!
