Rebuild the old alxe with new bearings and a locker of some sort?
Replace with a new GM axle of the same type as stock?

or f250 of the same years will get you 8 lug and a D60 rear instead of the 9"
both sets can be found pretty cheap. my D44 was $75 and the 9" was the same price. bought them separately.
'77 is the ideal year for the D44 so the wedges are welded on (easier to get rid of) the '79s have cast wedges and are a bitch to work around.
I've not seen many people have good about things to say about electric lockers but, I run in a small circle. I have seen one or two lockers for the 7.6 but, not much else. I don't even know if, I could find it again. Not much help, sorry.JaVeRo wrote:..............I like the idea of the Electrac but it is only made for the Dana axles and since Eaton bought out Detroit, It doesn't look like they will be expanding the product line any.........
Are you sure of this? This is the first that I have heard this but, you may be absolutely correct.drperry wrote:.........then the rear from any 5-speed S-series should be the 8.5" and you can get a set of 1.25" spacers.

If you really need locked and have an extra $1000 to spend we can give you some recommendations.

I am still a little shady on this. Maybe Miles will chime in.drperry wrote:..........99% sure on it... There might be a few that didn't get it... But most did.
As far as I know, all 5-speed Blazer's got them, anyway... And the 5-speed 4x4's got the iron front diff.
There's a few fleet 4 door Blazer's that have the 8.5" axle as well...
I can't remember what RPO code it is, though...
I am familiar with Jeremy's research on the cast iron front differential. Perhaps if, you had stated that any 5 speed "4WD" S/T series was an 8.5 or 8.6" rear diff, I might not have been confused. I'll go over the thread again and see where I may have gone astray Thanks for info.drperry wrote:So long as it's 5-speed, it should have the 8.5" and 3-button 4x4 gives you the iron front diff ...............
Wait a second here. Maybe, I misunderstood you again. I wheel with junk on D44s, D60s and a bunch of different axles. I witnessed a 3/4 ton 44 (with a Moser alloy Dana 44 MAX Front axle) go to hades this spring. I towed him out with a Lincoln locked Chrysler rear 8.25". Extra axles should be a requirement for any serious trail rig!drperry wrote:Also, unless you wanna have to carry two spares, you're not gonna want to switch to the dana axle
f9k9 wrote:I think we need to address the original problem. What is the reason that you seek an alternative? No locker at all? Something is amiss when you want to pull the diff cover for a " Look-see"!
drperry wrote:Actually a ZR2 axle will put the rear wheels a touch wider than the fronts, lol... I can't remember by how much, though.
I don't think that the frame is that much wider at the rear. You can poke around here. It hurts my head every time I try to find the differences!okie s10 wrote:Well DUH! Am I stupid or what? Gonna measure anyway, but it just dawned on me with ZR2 frame 4" wider than other S10's, odds are the springs are out a little further on the rear. Won't be able to do the mearsure for a couple of days, anybody know right off hand?
Actually the frame is the same width. I can not say that for the mounting points though.okie s10 wrote:... it just dawned on me with ZR2 frame 4" wider than other S10's
Stock specs from our websiteroadrunner wrote:Just a little off topic but is the rear track on my stock CC (01) narrower than the front? If so, how much and would it handle better in mud/snow if it matched the front?

2.1 inches narrower in the rear. There are many suggestions as for why. I think it handles just fine stock. Adding a wider rear makes up for the odd look we have with the Isuzu fender bulge. This really magnifies the difference.

S10 Crew Cabs have Isuzu beds.
I have no idea why GM did this.
Maybe because they partially own Isuzu and the parts were available which saved them money?
The rear door handles use the same GM thinking.
HenryJ wrote:You might get away with adding spacers to widen it out closer to the fullsize. I don't know the difference there.
Our bed came from the South American Isuzu Crew Cab. The faux flare was added to make it look like the S-series bed. Check out an Hombre next time you see one. It has the same Isuzu fender bulge on the rear fenders.
Have you seen the sticky?roadrunner wrote:Where and what size spacers are available and do I need longer wheel studs to use them?
Soaking fasteners daily, for a week or longer, with PB Blaster or Sea Foam Deep Creep helps with those rusted puppies. Anytime I am preparing for a mod I use that Heep advice.okie s10 wrote:Just finished last week the install of a ZR2 rearend under my CC. Was a snap, except for those darn ubolts.
