14 bolt FF - 8lug to 6lug????

[Tommy]

I havew just aquired a set of 3/4 ton front and rear axles. I know I can put the 6ug knuckles on the front, but has anyone ever redrilled or had the rear hub converted over to 6lug? My reason is I have a brand new set of Weld Wheels, and would like to keep them. Any Input????

Don't hold me to this, but I think there are some aftermarket suppliers that will make a axle shaft & hub that will allow 6 lugs for the 14blt. I just went with a s/f 14blt for my application.

Thats what I've been told, there is a source of the 6 lug hub, but who?

 

[Corey-88K5]

I'd try either Currie, Dynatrac, confer or warn. These all make replacement axles.

I think Dynatrac would be your best chance though. They can make about anything.

<font color=blue>Hey Corey, I'm planning on swapping in one of these rears since i will never need a ff because the max. tire hieght by law

in nj is 38". What did you have to do to put this axle in? what rim size/backspacing did you use? Who make alloy shafts and where can I get them? thanks</font color=blue>

I don't think it's possible to re-drill the stock hub and rotor for a 6 lug pattern. The reason is that the diameter of the protruding hub (where the end of the shaft bolts on) is big enough that there isn't enough room for the smaller 5.5" diameter 6 lug pattern. The only way I can see to do it is a completely new hub and axle.
Let's us know if you have any luck.

what sizer are your rims?? if they are 15" they won't work on a 14bolt anyways....correct me if i'm wrong but don't you need at least a 16" rim to fit on one of those?

 

[White Knight]

The only way to fit 15's is to change out the drums on the 14 ff to a disc brake conversion, TSM makes these at a reasonable price also. The drums are too large to stuff a 15 rim around....WK

 

[Goose]

What about the front? Won't the disc calipers on the 3/4 ton, 8 lug axle make 15" rims useless? Or is it just the 1 ton, 8 lug axles?

Biggray71,

I got a 93 3/4 ton S/F out of a P/U. I still don't have the axle under the truck. It currently sitting in the carport. I'm getting ready to make some perches like Depdog. As soon as I get that done, the axle will be ready to go in. I've already got the TSM conversion (15" wheels will fit on s/f 14blts with no problem), new lines, stock perches are ready to be put on if needed, and the "trick U-joint". So, as soon as I get off my arse, it will be in...

CORRECTION, 15" wheels WILL FIT onto a full floating 14 bolt rear IF the rear has the 11" brakes. These rears were used in light duty 3/4 tons, like 6800 GVW, just like my factory light 3/4 ton '77 Suburban 4x4. These 11" brakes are the same as the 12 bolts of the era.

If thats the case, my axles came out of a 78 suburb, could I redrill the hubs, then use the 12 bolt brake drums? Just a thought.

NO
