Damned Gov-lok! Blew up another one! New rearend needed!

It's not the ten bolt that is the problem, it is the gov-lok this time that cracked. It was a used unit that went in there last time when I got this axle. So the gov-lok is the weak point this time around.

My only concern with the 14 bolt is the re-welding the spring perches an shock mounts! I have no shop around here that I know of that I can trust to get the welding done correctly an accurately. I have a local welder but he is not a gear head welder, just a repair what you broke welder, or weld what you give him setup welder. He could know how to do it but I'm not sure!

I also don't want 8 lug rims. I like my custom billet rims an don't want to invest in a new set of rims an tires.

Now the 6 lug semi-float 14 bolt seem okay but again the welding custom work needed is a bit of a problem at this point. If it was a straight bolt up I would be all over it. A 12 bolt axle would be nice but they are harder to find.

I just need the rig back on the road in the fastest an cheapest way possible. I had always thought about upgrading the axles but I drive almost all pavement with towing occasionally right now so bigger axles isn't high on the to do list. Once I put the new 33" tires on I will be looking a little more into beefing up the axles since I just put my 3" suspension lift on the truck. I don't wish to go larger than 33" tires so a 10 bolt shouldn't have a problem holding up! This time the gov-lok seemed to be the week link which it is always known to be the weakest point in the 10 bolts since day one.

The issue with 10 bolt axles IS with the carrier be it a gov-lock or an open carrier, they just aren't up to the task once the tire size has been changed to any larger size.
 
Okay, the 14bolt SF came in 8 lug mid 80's 3/4ton trucks, which bolt in the same as any ten bolt.

Would the axleshafts from an 88+ 6 lug 14bsf work in the earlier housing?

That might be the best bet even if custom shafts are needed.
 
Looked around an the junk yards around here suck! No ten bolts, 12 bolts , or 14 bolts.

Only 3 places might have what I need an are going to call tomorrow to let me know. But the prices seem a liitle much at $500 bucks. Damn recycling killing all the good deals! They make more money scrapping the metal than keeping it now!

So any of you fellow wheelers have any axles in 3.73?

Otherwise it looks like I'm rebuilding this ten bolt that hopefully is still good. Damned gov-lok!
 
tons of info in this thread on 14sf rears. http://coloradok5.com/forums/showthread.php?t=286026&highlight=bolt

and like 4x4high said 10 bolt carriers suck. thats why guys say dont even put a lockright/lunchbox locker in a open diff on a 10 bolt. same stuff will happen.

and only good gov loc in my opinion and few others is a 14ff totaly diffrent setup for carrier and much stronger. but thay are only as good as a driver who knows its there AND how to use it correctly.
 
Looked around an found some 14 sf axles.

Is the 10 bolt a 42" center pin mount?

While the 14 bolt is a 40" to center pin mount?

So none of the 14 bolts came with the correctly mounted perches to match up directly as a replacement for the 10 bolts? Not the 9.5" or 10.5" ring 14 bolts?

Where can I buy new perches to weld on to the axles?
 
The only SF 14 bolts that will bolt into a K5 are the ones from a mid 80's 3/4ton pickup.

Those however have 8 lug axles, so an axle swap would be in order.

I forget the measurements, but any 1/2ton, k5 and 3/4 ton axles will be a bolt in deal for 73-87 trucks and 73-91 K5's. One ton rear 14 bolts are slightly narrower in the didtance between spring perches, and in a one ton you can only get a full floating 14 bolt.
 
question.


ive seen that the tru trac is recomended for only up to 32's, is that accurate??? i got 33's and was thinking on getting a tru trac for my 12 bolt..
 
Looking at the axles I also see that they came with three different versions of drums. But only one will fit a 15 inch rim? Which ones were those?

Also, who makes a 6 lug conversion for the ff 14 bolts with 10.5" ring gear???

15" rims fit even on 13" drums of 14ff axles.

few copanys offer 5-6 lug hubs for 14ff but then disk conversion or light fab work to fit drums is required. also 2 of there 5-6 lug hubs is around 550-600 bucks if i recall. then axle and work to swap it.

and if i recall you cant just swap shafts on 80"s 8 lug 3/4 ton 14sf rear to 6 lug. length diffrences.
 
Still searching local salvage yards an Craigslist to see what I can find. Might have a lead from a place in Arizona that has lots of old axles for sale for great price. Their shipping is a little high but if they have exactly what I want then it could be a good thing!

Gotta call tomorrow to see what they have!!!

What year did the 14 bolts get rear disk brakes as installed from factory? An can I use those?

not sure if I missed the answer to this, but didn't look like you got one
the 14bff from a 3/4 truck will have the correct spacing on the perches
it's only the 1 ton trucks that have different 14b perch spacing, cause of their frames
the only thing to look out for is the parking brake cables might be different

Thanks for the clarification!! That will make life a lot easier to find one of those!!!
 
14ff late 90's early 00' started disk rear.

and spindle changed and other things . so you need whole axle to swap it in.
 
I don't think you will find a 6 lug 14 bolt SF that will bolt up. The 6 lugs were on some 88-98 heavy halfs and light 3/4 tons. The spring perches (sp?) will have to be moved, but that's not too hard. You also may need to modify your drive shaft. The axles that were used in the 4x4's were also wider than the 2 wheel drives.

You should be able to take both your axle and the new axle to your local welder. He should be able to match the measurements of the pieces you tell him about. "Spring perches, shock mounts and pinion angle" Than take it home and bolt it in. Double check your rear ujoint as it might require a conversion joint though.
