Blazer vs 4x4 S10 rear width

Postby RonSS » Fri Jun 17, 2011 5:28 pm

Are the 2wd blazer rears the same width as the 4x4 S10 rear?
Still doing research on my brake issue.

I found one 96 blazer in the U-Yank it yard to go look and see if it has drums.
Of course I can't call them due to their automated phone system directing you to the internet.........

No sir the 2wd rear is narrower than the 4x4 rear by 2" and the zr2 rear is a wider than both....are you dealing with the 8.5 rear or the 7.625 rear?

I won't know till I go look at it because I can't get a human on the phone to tell me if it a 2wd or 4wd etc.
So Blazer 2wd rears are just like the s10 2wd rear?

Same width, however the bumpstops are different. They almost look like coil spring perches.

8.5" rear

I did some more research and the axle shafts are the same disc or drum. So that eliminates one variable.
Next question is the housing the same for drum or disc. If it is, all I "should' need is the 4 bolt flange backing plate drum setup. My "guess" is that since both the 8.5 and 7.626 both use the 2.75" axle tubes, they should work.
Of course it's pouring rain today and I don't feel like driving 30 miles to look at a blazer that might or might not even have a rear end in it, or might have discs.

Good news it that the driveshaft fit after I installed a 3R to 1310 conversion rear U-joint. I had replaced the harmonic balancer yoke thing that came on the rear with a used one that I bought that was a 1310 style. Sometimes I do get lucky. I knew nothing of the 3R style u joints. 1310, 1330, 1350, yes, 3R, never heard of it. The shaft has 1" of free play. Of course my bro had a 3R 10 8.5 10 bolt yoke sitting on his shelf after he replaced it with a 1310 style to match his Camaro driveshaft that he failed to mention......
