It always a possibility but the bearing is semi thermal distanced from the main area you need to apply the heat for metal heat expansion.

 

Excessive heat may damage the seals built into the bearing but a new bearing may be cheaper than the whole hub. I learnt a trick many years ago how to loosen frozen parts and that was to heat it up till the in your case axle stub till it's starting to glow then quickly pour copious quantities of cold water onto it. Don't be fearful of the cold snap damaging anything. The sudden heat change will shrink the axle. and it's likely to then fall out but as I said the heat will more than likely melt the bearing seals which may be difficult to find without buying the complete bearing. I don't see the bearing listed on ROCK Auto but it might be worth a call.

 

Not sure if applying so much heat is needed so much so to turn parts red. I think some may have failed that class of thermal dynamics…

As for cold or heat or both these when done correctly are often used in removing and installing bearings in motorcycle cases.

Most bearing have a number on them with exceptions of generic bearing suppliers. So those numbers generally can be crossed referenced in a bearing manufacturer cross over reference . Or the other way is getting out the micrometer (not a vernier caliper which are often not properly used) meaning and useing a bearing manufacturer or suppliers specification by size and type cataloging or reference information and find a bearing that will work. There are very few exceptions not to find a bearing .


A note about the use of auto parts suppliers … I recommend for best information never use their parts look up guides but go to the manufacturer and use thier parts guides and then buy from authorized sellers. Or roll the dice and hope you get the correct applicated part the first time

 

The heat should be applied to the axle. Directly on the end is the best place but you must quench it quickly. I learnt the trick many years ago to remove bleed nipples from wheel cylinders and it does work. Sometimes it's necessary to throw the rule book out.

 

wait what…. The last thing is to expand the axle ..

look we do this service at least every other week with suborn axles so while your way may have worked for you it is not normal.

While I try to follow the correct service procedures, I do often have what I think are better ways at times to do something but there are some things that worldly physics apply no matter how much you would like to change them.

I guess you never were an Aircraft mechanic cuz the rule book applies and is required. lol

 

Trust me it will work.

 

See here is the thing.... when you go "off reservation" and defy the laws of physic's based when it comes to working on any vehicle be it car, truck ,boat etc., or even an Airplane, you hope that non-conventional procedures and wisdom will work. But there are just things you don't do when it comes to customers vehicles, the regulation of some serving procedure like working on an Aircraft and basically your own personl vehcle you just don't suggest to other they should try.
But that's just my opinion maybe supported by the empirical facts and information if one looks.

Sorry , but I do understand the thought and suggestions for a very DIY experimental service method designed to help a DIY member.

Below is a very important thread for all members to read and think about :

Automotive Forums

Another source of information many people use on the internet are automotive forums. There are hundreds of forums dedicated to specific vehicle makes and models as well as more general automotive forums. Forums contain a wealth of information, but also a lot of misinformation and conflicting information.

The typical forum user will post a question in hopes that other forum users will respond and offer an answer or advice on how to solve the problem. But with all forums, there is no guarantee that anyone will respond or that any responses they do receive will be accurate or helpful. It all depends on the other forum members and who posts a response. Many forum users are quite knowledgeable and can provide exactly the kind of answer you are looking for. Other forum users want to be helpful and may venture a guess or offer an opinion that may or may not be accurate or may be totally wrong. In other words, it may be hard to distinguish good advice from bad advice.

Most forums are moderated to delete spam, rants and off-topic posts and comments that don't belong on the forum. But in most instances, the accuracy of the posts and responses is left up to the forum users. There's no editing or vetting or review of the comments that are posted. Consequently, if inaccurate or incorrect responses are posted to a question, other more knowledgeable users may or may not challenge a post or offer additional information.

We've seen many forum responses degenerate into endless bickering between conflicting points of view. We've also seen a lot of posts that totally contradict one another. There's nothing wrong with a good debate provided the people involved know what they are talking about. But unless there is some resolution to the debate, or some serious fact checking involved, the person who posted the original question may be left confused and no closer to finding an answer than when they started.

 

Another alternative since you have removed the complete assembly is stand it up so the mushroom is on top and fill the cavity with Hydrochloric Acid. It may take a little time but will effectivley disolve the rust which is in my opinion preventing it to be dismantled. Unfortunately I have never seen rust taken into consideration in any mathematical equation.

well that shows where your education DID NOT GO!!! sorry but I love math and even belong to a Quantum physics and theory forum. Yes a pocket protector NERD thats me!
Rust can be used to create mathematical algorithms


um so lets get this straight because rust was not mentioned a few of us missed something? ya.... no I don't think so!!! . Parts that are precision pressed fit when they become difficult to service penetration fluid is the last on any good service mechanic or higher service Tech to use. In fact in almost every case all it does it make a mess and wastes time.

.. read this ! Then maybe other may think twice before trying your idea? IDK then again, we do have some members that are desperate.

Hydrochloric acid is a highly corrosive substance that can cause serious harm to the body. The dangers of hydrochloric acid include:

Inhalation of vapors can cause burns to all body tissues, lung damage and even death in extreme cases.

• Ingestion of hydrochloric acid may lead to potentially permanent lip and mouth damage, esophagus or stomach damage, vomiting, and difficulty swallowing.
• Concentrated hydrogen chloride can be corrosive to the skin, eyes, nose, mucous membranes, and respiratory and gastrointestinal tracts.
• Hydrochloric acid in contact with skin or other tissues can cause chemical burns that can be severe.
• Hydrochloric acid in the eyes can cause blindness.

 

You obviously have never taken one apart. The axle is splined and is not I repeat not a press fit. The hub is another issue but the op is trying to remove the axle from the hub.
