red locking hubs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

charlieo · 03-17-2003, 12:03 AM

I'm restoring a 69 GMC 4x4 . The front locking hubs need to be replaced eventually . The hubs are red on my 69 and are blue on my 72 . Does anyone know why GM used these different colored hubs , and does anyone have any red hubs in good shape ?
Thanx !

sakohntr · 03-17-2003, 12:34 AM

Which are you refering to? You can still buy new ones from GM but they will be yellow. Do you have the half ton or 3/4 ton spicers. Blue ones are hard to find and i have never seen an NOS pair of red centers for the 1/2 ton style.

blazerboy72 · 03-17-2003, 08:11 PM

i will have some blue ones as soon as my lift goes on if you want them.

ozarkhippie · 03-17-2003, 10:43 PM

I think the red ones are used by ford, gm used the blue and then went to the yellow.

1969 GMC · 03-18-2003, 01:39 AM

my 1969 GMC K2500 has locking hubs on the glovebox option sheet and they aren't colored. they appear to be just grease-covered metal to me. Is this because it is a 3/4 ton?

ZOOMY · 03-18-2003, 05:40 AM

My divine 69 has red lockouts & the 71 has blue. The 72 is converted to warns, but I think they were blue also. All are 3/4 tons........Zoomy

ckhd · 03-18-2003, 11:01 AM

1969 GMC, sounds like you have the same spicer hubs as I do on my '68 K20. I don't know when they went to a larger plastic knob, but I know it was changed by '72.

1969 GMC · 03-18-2003, 08:02 PM

Yeah, my front hubs are monsters, they're bigger than the rear hubs, they don't look like the classic Warn design, the dial doesn't have the 2 kidney shaped depressions, its just a straight line that you turn, no plastic anywhere.

Dean · 03-19-2003, 10:35 AM

The Red, Yellow and Blue knobs on the 3/4 ton spicer hubs will all interchange. Blue is what was on our trucks, Yellow was on later 73 & up chevy and red was on the fords. You can still get the knobs from spicer but you will most likely get a red one. Chrome rings are also still available from spicer if you want to spruce them up. Gaskets are available from GM. I haven't been able to find much else available for them.

Dean · 03-19-2003, 10:38 AM

Here is the Red "Ford" knobs.

**CPNE** · 03-19-2003, 10:03 PM

What Zoomy said is correct from my observations. At some point by or during 69 for 3/4 tons they went to red plastci dials that say "Spicer" on them like the blue 71/72 style. They used red in 70 too. 67/68 maybe some 69's used the metal ones like 1969 GMC has.

**Canadian694x4** · 03-21-2003, 08:18 PM

I have red lockers and I will have a pic shortly when I get my Picture Cd processed tonite I'll post it later for all to see...

**Canadian694x4** · 03-22-2003, 01:09 AM

I don't know enough about them so any info to help the cause...

nu2-72 · 03-22-2003, 11:09 PM

I recently ran across a guy with a basement full of junk. Here are a few of what I got. More of the same in some other boxes. Never know when I might need spares and I can't tell you the price. Let's just say, "DEAL."

**jerry moss** · 03-25-2003, 12:15 AM

Kevin,
did you sneak into my garage?

nu2-72 · 03-25-2003, 06:58 AM

No, I knocked. Nobody answered. Knowing how friendly you are and how you would want me to be at home in your home, I was. LOL

**jerry moss** · 03-25-2003, 10:41 AM

Kevin,
you even had my wife laughing.

nu2-72 · 03-29-2003, 08:30 PM

Glad I could be of some use Jerry. I make my wife laugh too, but she says it is because she can see me.

1969 GMC · 03-30-2003, 04:26 PM

I was just thinkin about this, could the different hubs correlate to open/closed knuckle Dana 44's? My GMC has closed knuckles and big hubs. I think 69 was the year they started using open knuckle 44's, and possibly when they switched to the Warn-style hubs. I guess my closed knuckle was just a leftover they had to get rid of, kinda like my married Rockwell t-case.

nu2-72 · 03-30-2003, 05:11 PM

The GM parts books make several references to different part numbers related to the red hubs. If you like, I can get a copy of the pages Monday and scan them for you.

**Canadian694x4** · 03-31-2003, 01:01 AM

I'd love a copy too please....

charlieo · 03-31-2003, 02:30 PM

I have the Dana (3/4 ton) hub manual and parts list if anyone needs it.
