What is the name of the glue you used to repair the engine and where did you buy it? Where the Axle meets the differential it seeps a little oil. So while I have it apart I thought I would glue it.

I have proof the previous owner removed the differential cover. Notice they put the cover on using black RTV. I can buy a cover gasket.

They had to if removed a lot of metal and broken teeth and decided to sell it. I don't think I could see anything knowing it has a problem and not tell the buyer.
Thanks
George

George it?s called PES 101 . Here a link

Thanks.
A little on the pricey side.
Is there a cheaper alternative that stands up to oil?

How were these initially sealed?

Geo-TH,In · Apr 4, 2020

You tell me how it was built.
I have no clue. No sign of welding in the puc.

David G · Apr 4, 2020

You got me curious, so I looked, seems that they were pressed in, then spot welded. There is a vast difference of opinions on how to fix these, seems like welding, RTV and JB weld are most common. I would believe that if it is not loose RTV or JB should work.

Other opinions are encouraged.

George I?m afraid you?ve got other problems looking at that axle

Geo-TH,In · Apr 4, 2020

David,
I'm not an expert when it comes to welding.
The long axle appears to be steel.
The housing appears to be cast.
Not sure welding is the answer.
It possible the axle is heat fitted to housing.
Welding may weaken the axle and not bond well to the cast.
No expert, only guessing.

Ok,
What's the bad news?

Russ from MN · Apr 4, 2020

Geo, what did you use when you were gluing gas can spouts? Has anyone used JB Weld with gas or oil? I have been pretty impressed with JB Weld.

Geo-TH,In · Apr 4, 2020

Russ,
Like some predicted the glue didn't hold up.
Isn't some JB the same, doesn't hold up to oil or gas.

The axle does not look aligned with the housing. if it is bent, the new gears will never last. If it is on concrete, (or can be put there) measure down to the floor in 4 places. out at the wheel end as far as you can get and still measure to the tube, right at the spot where the leak is, on the opposite side close to the housing, and away on the far side as far as possible. if the floor is pretty flat, there should be less than 1/16" variation (or none) Jim

Looks like a Dana 44 center.
If yes, the only time I have seen the tubes leak at the center section is when they were abused as in jumping jeeps on the sand dunes.
The tube and socket is machined then press fit together.
The older ones were then plug welded after and then furnace brazed to get a good seal.
The newer ones are sealed with silicone on the end inside the center section.

DANA would also run a batch of center sections with axle tubes.
The ones that were not up to automaker use quality would go to small time manufactures.

Geo-TH,In · Apr 4, 2020

Once I remove the carrier I'll use a string to check if the centers align.

Steve@Advance · Apr 4, 2020

Could be just the camera angle, but looks like it is bent.

Have you sighted through it? Or pull a string through the middle, take some measurements.

David G · Apr 4, 2020

Geo,

I do not mean any disrespect, but it looks to me that this job is above your experience to execute. Based on the level of damage, the unit needs to be totally disassembled, cleaned, checked for alignment then have damaged parts replaced. I would think there is a local shop that could do the job.

Other posters that see the bent axle, can you explain what you are seeing?

Having been around redneck 4 X 4's all my life I've seen more than one that appeared to be "tweaked" a bit like George's and just kept slinging mud. There would have to be quite a bit of misalignment to damage to quickly damage the differential gears as there's some play in the splines and the spider and side gears are not a real close fit. Especially in a slow-moving machine used around the yard.

If all that is wrong is the spider and side gears and those are replaced I'll bet the repair will outlast George and many of the rest of us on here.

Wish I had a photo at hand of the front differential cover from my 1974 F150 that I welded up twice after breaking the spider gears being a teenager and having chunks get shoved through the steel cover! The axle is "curved" a bit like George.s and I drove it for THOUSANDS of a bit more gentle miles after the last "crunch" episode.

The axle in that old Ford is also a DANA 44.

Sure, if money, time, travel and lockdowns are not an issue there are 4X4 specialty shops that could build a new axle from scratch, which would probably be the ultimate fix, but again, if the ring and pinion are not damaged or the cross pin ripped loose in the carrier it will go a LLLOOONNGGG way with just a new differential kit.

george, im not sure what that is for , but if it needs to get re tubed or anything else, we use strange engineering in morton grove for our hot rod builds. good people, and their work is impeccable. here is a link.

That picture is really cool.

How do you get the tubes in/out of the housing and seal them?

Every darned magazine rack 4X4 truck magazine used to cover that stuff 25 or 30 years ago.

A quick Youtube search brought up the video linked below of a DANA 44 FRONT axle re-tube.

Although it's a FRONT axle in the video, the tube changing process would be the same, but, of course, what gets welded on the outer ends of the tubes is different

NEAT video.

David G · Apr 4, 2020

That is super cool, thanks.

SVcummins · Apr 4, 2020

Measure and see but it looks Like the axle tube has come unwelded from the center housing that might be why it?s leaking and also why the gears broke .

SVcummins · Apr 4, 2020

To answer your other question no I have not had any luck with jb weld or permatex cold weld on anything with oil on something that has any flex to it like an axle or engine block or transmission housing . That?s where the pes or belzonna comes in because They actually can flex with the whatever you apply it to

MarkB_MI · Apr 5, 2020

I was wondering what caused the differential gears to fail; you just don't see that very often. The bent housing could also explain why the carrier wouldn't come out.

Did the terramite roll off the trailer without ramps?

Geo-TH,In · Apr 5, 2020

I bought this from a DIY rental.
Hard to say how much abuse it had in the past.
I use ramps.

Geo-TH,In · Apr 5, 2020

David,
How do I find someone who can do this kind of work?
