Re: 1980 F350 4X4 C6 Project

This post was updated on .

I started disassembling the front passenger side hub this evening and I ran across something I have not seen before. The nuts that torque against the bearings have 6 lug recesses on them. Every video I have watched has only 4 lug recesses in these nuts. Does anyone know what size this socket is that has the 6 lugs?

Update: Looks like it is 2 5/8 outer spindle nut size.

I'm glad you figured it out as I sure didn't know.

Hey Gary, do you remember back a couple months when you were helping me figure out the springs on my truck? I ran across something today that aligns with your post of the 1981 F350 with the 9100 GVWR. I ran across a Certification/Model label decoder in the front of the MPC. On my door label it says my "Type - GVW" is F361. When I looked that up in the chart, here is what I found:

Built in 12/1979 my truck is clearly a 1980 but the MPC fails to recognize it in multiple places. Just another layer of the onion I guess!!

The early dana 60 axles had a 6 lug nut. At least my 78 does. This is the socket I bought to use.

It has both 4 and 6 lug.

Thanks Bruce! I like the idea of having a socket that will do both the 4 and 6 lug spanner nuts. My front axel is a Dana 50 and I know they shared a lot of parts with the Dana 60 so I’m not surprised that the nuts would be the same.

I just thoughtI need to clarify, The 4 pin is for the smaller Dana 44 spindle nut. It is not the bigger 4 for the later 60's and probably the 50's. I have never worked on a 50.

I tried removing the front passenger spindle a couple days ago with a maul and a chunk of 4x4. It wouldn’t budge so I ordered the spindle socket that attaches to a slide hammer.

The spindle came out of the knuckle in 2 minutes!

I also noticed the brake dust shield is in rough shape. Does anyone make replacements? A quick search of the usual places has come up empty.

I'll have to remember that. I fought the spindle on Huck for a couple of days!

But I don't think anyone is making the dust shields. Mine were so bad I'm running w/o them.

I'm disappointed that the big can of pb blaster didn't make it slide off like butter.
not sure that anyone makes replacement dust shields as I have never been able to find them either. it one of those less sought-after parts that I seek on resto jobs too. often going through the work to get to them at a yard simply because they are there when I'm treasure hunting. we do a ton of fab work in the shop and have even considered trying to come up with a set / pattern.but if i did then I would have to know dimensions of who knows how many models unless I made to suit each time. time is money and that gets it moved to the back of the line.

I looked everywhere for them, some places claimed to have them in stock, but when I placed the order, their stock disappeared. I wasted several weeks on those cycles. As I recall, those prices were all around $50-$75 apiece. Finally I found a pair on eBay for $200. They are very hard to find, but they are out there if you keep looking.

Like Gary, I struggled for a week to get the spindles off. I made a slide hammer tool, my spindles just laughed at that.

Finally built a real tool and got them to pay attention.

It's now available for passing around as needed, should anybody be fighting the battle Gary and I did.

Nice looking tool, Pete. And a generous offer to loan it. Sure would have saved me a lot of work.

I've just posted a new thread about loaning tools and posting files to print here, so please let me know in that thread what you think.

Is there a secret to seperating this joint in the front passenger axel shaft?

I keep moving it back and forth and it seems to come out more each time but it has not fully released yet.

In my case it took a lot of pushing in and pulling out, and the pulling out had to be done rapidly to get the momentum. It acted like the grease had set up and was preventing it from coming off.

Re: 1980 F350 4X4 C6 Project

Got it out! It did take quite a few sharp pulls to get it to release. I think the grease was more like glue on mine!

With the axel shaft out I moved to removing the knuckle. Both the upper and lower ball joint nuts were very crusty but both let loose at the end of my 5 foot breaker bar. I rented a ball joint press from a local auto parts store and they came out of the knuckle fairly easily.

I used the ball joint pickle fork to remove the camber bushing.

After I cleaned up the top I was surprised to see that it was a 0 degree camber bushing. Given the state of the worn out suspension I guess I figured it was going to be something on the positive side.

Progress!

On the camber bushing, I'd go back with an adjustable one so the alignment shop can dial it in.

Re: 1980 F350 4X4 C6 Project

I got the passenger side ball joints pressed in tonight. Nothing to eventful in that process.

I do have a question about the adjustable camber/caster bushing. Would it be a good idea to use anti-seize between the bushing and the axel tube? What about between the bushing and the ball joint shaft?

Yes and yes. You are going to want it loose at some point, and it is easier if it hasn't rusted to another part.

Re: 1980 F350 4X4 C6 Project

The knuckle is back in the truck!

Question…are the spindle nuts locking nuts? I ran a thread restorer on the studs and the nuts and none of the nuts would allow the restorer all the way through.

Congrat's!!!

The nuts are "prevailing torque", which means that they aren't round and squeeze the stud to keep from backing off. So you shouldn't run a tap or thread restorer through them.

Re: 1980 F350 4X4 C6 Project

Is there a torque spec for those 5 spindle retention nuts? I looked in my 1980 Ford Truck shop manual and there is nothing listed in 15-34. It just says "tighten" on page 7. I looked at the end of that section as well and they are not listed in the table.
