4681 Wagon axle rebuild

Has anyone rebuilt a wagon axle? Are the bearings/seals still available? how much $ and where? Also does anyone have a diff section that they are willing to sell? I dont want to buy many $$$ in bearing to find that the ring and pinion are shot. I also dont want to take it apart to inspect and find that I can t get the bearings/seals.

Tha axle howls like a lonely werewolf at speeds above 45-50mph. When I first got the car running it would start at 30mph. I has gotten better and better, but has reached a point where it has leveled off. It only howls under load. The more load there is, the quieter it is. 60-70mph constant speed is pretty annoying. If you can get the car to "set" to one side or the other, it quiets down a bit. But if the car shifts, or you accel, it gets loud again. I think the carrier bearings are shot. I just hope it hasn't chewed the ring and pinion too.

The seals must be available I've seen Ray rebuild a couple. Next time I talk to him I will as for the part numbers.

Just buy another wagon axle(whole assembly)

Unless Im retarded the same bearings are used all the way up to the 80s in those straight axles
Napa has them for my 521. I think the wagon usues the same bearing. But taking the bearing off is the pain and have to have it done at a machine shop

I dont want to pay what it would cost to buy one an the shipping from Cali/Wash/OR to get one. Datsuns are very rare here in the South. I bought the third 510 I have EVER seen. And I am 35 years old. Will a late 70's 810 wagon axle fit? Probably not. There is one in the local wrecker that I have stripped all of the door rubber out of theough.

If any of you guys have one for cheap or free and are willing to ship it, I am fair game to pay for that. I would imagine that it would have to go by frieght company. I'm REALLY not looking forwarf to building an axle. Ring and pinion set-up scares the hell outta me...

I would think that all you need to replace is the center section- unbolt the axles to pull them out, then pull the 3rd member, which contains all the gears and half the bearings. Heck of a lot cheaper to ship.

You can probably use the center section out of that 710 in the salvage yard. Partsamerica.com has the bearings. This is a pretty easy job to do.

Yeah, thats what I originally asked in my post. Will a 620 or 720 diff section fit? Those are pretty common in the wreckers here. They just got a new one in that is in REALLY fantastic condition. To be that nice, it would most likely be pretty low miles too. Looks like one of the famous "grandpa never drove it much" trucks.

no man, you need a 510 wagon diff.... and they are like gold. i drove 7 hours down to oregon to score mine after it locked up going 40 down the road . there IS NO bolt in swap. start shopping around and in the meantime take it real easy on that diff. once you find yourself a replacement i would look into trying to rebuild (or have it rebuilt at a shop) what you have. once it locks up or shatters or whatev its pretty much garbage. i hucked mine in the bushes outside my work.. randys ring and pinion said it wasnt salvagable... good luck with your search man, its a bitch.

also if you have some fabricating experience, ive seen several axle swaps be done. check around on some other forums and check out whats being done to get LSD's and more readily available rearends back there. it can be done!

The truck diffs fit IF you change out the side gears, because the axles are different sizes. However, the gear ratios are different.

That's what I was referring to - swapping out the spider gears. mklotz was telling me about this.

You mean to put the 510 side gears into the truck center section. Which trucks? 620's.

I think I will return to mu original plan to swap a corola axle in. It is a couple inches wider. so I will have to figure what to do about that. I was going to run 25mm 5-lug conversion adaptors on the 510 axle. how I wont have room for them on the corolla axle. Gotta figure out how to convert the corolla to 5-lug... i gues I could get some dual pattern wheels... 5lug on the front (200sx V6 struts), 4 lug on the rear...

I've never seen dual-pattern wheels with 4 and 5 lug- it's always 2 different 4-lug patterns.

720 rears would have a ratio a little closer to the wagon ratio. 620 Truck ones will be awful high (numerically) and rev the engine way up.

They are not uncommon in old JDM wheels. We have a couple of customers with them. I'll try to score a set off one of them. To see some dual pattern wheels. Check here:

The 710 uses a H165 mm ring and pinion, I think the 510 wagons used a larger one.

What years 510 wagon axle will swap directly in? I have found a 78 wagon...

'68-72.

A '78 used a H165.

Remember, the '68-72 510 wagon used the H190. The ONLY vehicles to use the H190 were '68-72 510 Wagons, '67-70 Roadsters, and '67-86 trucks (later truck ones used different bolts). It's possible the 411 used it too, but I don't know for sure.

However, all 3 vehicle types used different axle shafts and hence different spider gears.

So a 67-86 truck center section will bolt in if I swap the spider gears? Anything to that? Machining? Or just a matter of diggin the nasty little bugges out. Dont ya just love gear oil?

Here is my understanding. Use 510 axle housing, bolt truck center/diff section into it after swapping in the 510 spider gears. I use 510 axle bearings and seals and 510 carrier bearsings. But I use the truck pinion bearings (if needed)...

What do you mean by "different bolts". Also is there a particular year truck I should look for. As I sit now, i run out of gear at about 80mph. Something in lower than the 3.90 wouldn't hurt my feelings at all.

The trucks will be worse- remember, the '70-72, 74-79 trucks use a 4.375, the '67-69 & '73 run 4.88, the '79 Manual and '80 run 4.11, and the '81-86 2WD run 3.875.

I had a friend swap the spider gears on a wagon rear to the truck version so I can make a freeway truck at some point. I don't know what he did- he wanted 4.375s and I had a set.

maybe one of the so-cal guys can pick it up and ship it for you...
