Although I haven't done the mod you posted, I have done similar projects in years past, as a machinist. Even though you are welding a small area, you run the risk of creating a weak spot on the axle, causing the axle to break at that point.

I have not yet experienced changing the Zuke axle bearings. Looking at the photos, I think maybe the "bearing retainers" you refer to only provide a surface for the seal to run on. If true, a better fix than welding may be to simply use a center punch about six places around the axle where the "bearing retainers" are located. In effect, that would be similar to knurling the axle. I doubt you would have to go very deep with the punch, and it would hold the retainers in place.

I see, so welding and especially subjecting a small area to high heat can cause that part to weaken, now I see your point. The axle can break due to this, unless perhaps you use mig weld to minimize too much heat perhaps?

Oh well, might as well do this the hard way, but the right way. I do not want my axle to break on the highway.
Thanks for your advise sir!

You are welcome.

It would make no difference which weld method you use, you run the risk of causing the part to fail due to heat. Keep in mind, there are some applications this method would not be of concern., but on an axle I would not do it.

For reference, the correct dimensions are 35mm ID x 48mm OD x 20mm thk. Many retainers are 50mm OD. It will NOT work.

I checked out the entire local NAPA warehouse recently. Only one was correct out of around ten.
Hmmm...

Just replaced a NAPA bearing and seal that was less than 6 months old.

The thread/post can be old and still be valuable.
