Good to hear.

When I was buying u-joints last there was an option for 4wd "w/sport option" which I can only assume is ZR2. It has a bearing OD of 1.188". CLICK

The ones I bought are for 4wd "exc. sport option" and have a bearing OD of 1.125". CLICK

It looked like the bigger u-joints wouldn't fit in my stock driveshaft or yokes, which is why I asked. The endcaps were significantly larger.

 

That is interesting... although I don't know i'd say that .063" is a significant difference


Ill crawl under the truck tomorrow and make sure everythings still all good. I havn't had any clunking/noises/whiring/womping etc so I don't anticipate any problem!

Edit: Didn't realize U-Joints were so cheap though..I shoulda swapped those while I was under there! Maybe tomorrow haha

 

Hahaha, I suppose you're right. But the endcaps looked ginormous compared to the stockers.

Also, I'm not trying to scare you with your install. Just asking because you were under the truck more recently than I and this is a swap I want to do so I'm trying to glean as much info as possible before purchasing.

BTW, if you find any more $150 steals, let me know. Gas money down there and back plus $150 is still cheaper than anything I can find around here.

 

Yea... where was this deal in the craigslist/ebay section so we could all drool while you went to buy it? huh huh huh?

 

Well, I just bought a zr2 front differential and a rear 8.5 both with 4.56 gears and the rear has a Detroit truetrac limited slip. I'm gonna be installing the rear in about a week when I get a day off.

 

Siiiick!

Glad I could throw you the lead

 

I'm wondering how much (or if they will at all) stock rims would stick out on the rear. I have access to front diff and a rear axle from a ZR2 blazer for 150$ for both, and I'm thinking about the swap.

 

The ZR2 axle is 3.9" wider than the stocker...so the wheels would be 2" wider on each side. Look for pics of a blazer with aftermarket rims that are 4" of backspacing and it'll be that same width for you.

 

then it should look like yours did with the stock axle? perfect IMHO, the back is sunk in too much on the 4x4's stock anyways

 

Yep, Thanks man!! With as much time as I spent searching, I still can't believe I couldn't find that post. I just hope everything works, cause I doubt he'll drive 2 hours to meet me halfway again if something doesn't work. But, he told me everything worked perfect for him, I just have to fix a brake line on the rear and definitely repaint it. Will the CV from a 2000 zr2 pickup fit our blazers? He couldn't get the driver side cv off, so now I've gotta see if I can get it, unless it'll work.
