Stovebolt.com Forums The Parking Lot '60-'66 Trucks C10 Front Spindles the same for 1960 through 1966?

Hi Everyone...

I ran into an issue with one of my spindles on my 1960 Chevy C10. I understand the spindle is the same on both sides (drive vs passenger), but does anyone know if the spindle changed between the years (1960 to 1966)? I found one for sale that states it is for a 1960 to 62 and then I found another one from a 1964. Looking at their pictures, they look to be the same, but was hoping someone knew for sure.

I did find out that the hubs from 1962 to 1968 trucks can fit onto the 1960 spindle (Thank you red7218!!!) leading me to believe the 1964 spindle is the same as the 1960 spindle.

Any help would be greatly appreciated...

P.S. I am not interested in upgrading to disc brakes or lowered spindles. The truck is 95% stock besides tires etc and I want to keep it that way.

As I remember, the bearings and hubs are the same 60-66. The nut that holds the wheel cylinder has different threads in my 1963 compared to my 1965 IIRC.

Hey Lugnutz...

The bearings and hubs are different because the 1960 and 61 hubs used ball-bearings (which require much more maintenance) and the 62 and above use roller bearings. So, the 60 to 61 hubs have a bigger diameter hub for the ball bearings to fit and have different spindle nuts and washers along with a different cap than the 62 and above (with smaller diameter hubs, washer and cap).

My problem is the spindles. I have read they have different part numbers between the years, but I was hoping to hear from someone who can tell me from experience.

Sorry, I am not the guy who bought the fleetside fenders... I have 2 step-sides and 1 dump truck... no fleetsides....

Thanks, Russ

Russ,
Ahhh! I seem to learn some thing new all the time about these trucks. I did not know the differences that you mentioned about the front wheel bearings.

I sold a fleet side rear bumper (not fenders) to a guy in New York. To the best of my memory, he lived on Long Island, but I could be wrong about that.
I put the 1966 fleet side rear bumper up for sale locally on craigslist. Apparently photos from craigslist appear on websearch images. He was looking for a 1960s fleet side rear bumper with nice patina and was casually viewing images on websearch. He clicked on the image of my bumper and it led him to my craigslist ad here in Columbia, SC. He called me and asked if I was willing to ship it. I was surprised that someone was willing to pay for shipping all the way to New York. We made the deal and I believe he’s a happy customer.

Can't seem to find '63 in this parts book from Sept 1972.

BTW, been running newer hubs w/ roller brgs on original '60 C10 spindles for several years.

Hey BC59...

Yes, that is my goal... to upgrade to hub's that use roller bearings instead of ball bearings. It is because of the ball bearings that I need to replace one of the spindles which need to be done before tackling the hubs... Can I ask what year hubs you are using on your 1960 c10 spindles? I understand you can use 62 to 68 hubs.

Thanks, Russ

What does D-D mean?

Ask old parts man, he said "double duty", step vans & such.

Thank you.
That solves a mystery I've had for years. I see it on Vin tags and I see it in parts catalogs. My take is when on the top of a Vin tag (DD) it was for the Delivery Date to be stamped by the dealer. Most were not stamped. The paper work was suffice.

When in a parts catalog it means, what Chevy called, a Dubl Duti. Package Delivery style truck and etc.
Thanks again.

Just updating this for future readers...

I was able to find a set of front hubs and from what I was told, they are from a 1968 to 1970 Chevy 1/2 half ton truck. I used the supplied bearings with the hubs and they fit fine on my 1960 front hubs. Just remember to take the 1960 race off the spindle before installing the newer bearings. One came off without issues and the other race took some time, a puller and heat to get it off! I have been driving on the new hubs and bearings for several months (Weekends) and they seem to be working well !! Now I plan to take the bearings out, clean them up and find replacements at the auto store to determine which year they are from (Have not investigated if 68 to 70 use the same bearing).

As always, thanks to everyone on this forum for your help! Love these old trucks!

1962 - 1970 1/2 ton hubs should all work on 60 - 61 C10 spindles to convert to tapered roller bearings.

What is the advantage of tapered bearings?

Hold an older ball bearing in one hand and a newer tapered roller bearing in the other hand and you will say, "Oh!"
The older ball bearing is just an oversized "bicycle" bearing. More expensive, too.

The cost & availability of the tapered roller bearings is much better than the ball bearings.

That's good. Thanks

Lower cost is always good. A rarity these days.

Just like they said... some of the advantages are:

1. Cost
2. Availability
3. Maintenance.

I was trying for a while to keep the truck stock, but as I get older, I realized convenience is more important. The roller bearing always seemed to need adjustments and would fail if not performed or performed incorrectly. Then finding replacement ball bearing type bearings was getting harder and harder and more and more expensive ($50 to $90 per bearing times 4 for both sides vs. $3 to $8 per bearing if memory serves). I also noticed some of the replacements no longer had metal casings. They were using plastic! I also feel the roller bearings tend to 'push' against each other which helps to keep them in place and the ball bearings type do not.

Hope this helps!

That is good info. If you had a problem you could change then. I'll baby mine until then. I don't drive much.
I saw the plastic too. Luckily I had a choice.
