1 ton diff - any use?

[Tanner]

Okay, so what value is there in a 1989 GMC 3500 rear diff from my parts truck?

I'm looking to yerk the 6.2 out this weekend & sell the TH400 trans & possibly the diff - or just let the rolling hulk disappear from the driveway when the heart of the truck is removed...

Tanner, do you know if it is a locking rear end or not?

Being a 3500, it should be a Corp 14b Full Floater. I wonder what gears are in it...

Whats the rest of the truck like? Glass, interior parts, fuel tank, etc might be useful to people with 1008's.

tannier do know if its is 4x4 and include front axle also

Also like mangus580 said do you know if its locking rear end or not?

i got some family that lives close to you and will be coming there soon. Got a guy here looking for the axles, and im interested in other parts. i could get you some decent money for the axles if you are interested in selling them front, and rear. Pm me with what all you are trying to get rid of.
thanks

The important question is, being a '89 is it the 88-98 body style or the 73-87(91) body style. There was some overlappage of the two body styles.

A plain ol' 14FF could easily get $100 but not much more unless it's got good gears and/or a traction aid. 14FF's are more commmon than the D60 so they won't go for the big bucks.

A d60 front is popular with the rock crawlers and they go for good money

It's a 2wd truck, I bought it for the 6.2 engine & had planned to scrap the rest of the truck...

It's the 89-up body style truck, close to 200k on chassis - had replacement 6.2 installed - rots o'rust in bed & rockers, mechanicals are good, so I'm putting the trans up for sale & was considering putting the rear axle up for sale for a Benjamin... but posted here because I don't know, without doing a bunch of research, whether it fits any CUCV's or not -

As far as gearing or traction aids are concerned, until I locate a build sheet, I have no clue...

It won't bolt in but simply cutting and moving the shock and spring mounts would solve that issue.

 

[Tanner]

It's a good diff, we've been driving the truck, but I don't need it for the M37/6.2 swap, so I figured I'd look to cash it before scrapping it -

[AJMBLAZER]

Any idea on the gears or what diff is in it? Anything lower than 3.73 would be desirable.

 

[Tanner]

I'll be looking at the truck/working on it this weekend - will check & see; hope to con Cabell into helping pull engine out Sunday afternoon!

For the record I'm not interested, just trying to help ya out.

Had it been 4wd it would have had a solid front axle. 1-tons, K5s and 'Burbs stayed SFA until '90 or '91 I believe.

I think that was only true of the old style trucks... Making only the dually/crew cabs SFA

 

[AJMBLAZER]

It's more confusing than that actually. In 88 you could get a regular cab 3/4 ton and 1 ton in the old body style or the new one. The old style trucks are rare though.
By 89 it was only the crew cabs 1 tons that were the old body style. Crewcab chassis cabs, pickups, and duallies where all old style while any regular or extended cab truck was the newer style with IFS.

tanner does it happen to be a crew cab?

No sir - it's a civilian 2 door cab GMC 3500 truck - '89-up body style, not the CUCV style cab...

Cabell & I were discussing the merits of keeping the diff under the truck for ease of hauling the carcass away after removing the 6.2 - Was curious to know if diff was worth $100 to anyone, thus the reason for my post...

that rear axle if it hasent been rebuilt would be worth ~$75 since @ 200K its in dire need of a rebuild.

Agreed, but if I start at $100, it's easier to go down on price, right?
