Well, I am no beauty either!

I was at Wal-Mart waiting near the Isle where the Women were looking at the beauty Potions and it occurred to Me that if any of that stuff really worked the Husbands and Boy Friends would be the ones buying the Stuff for the Women.

ebay? McMaster?

I bought mine really cheap in a lot of precision measuring tools from an electronics firm that went out of business.

I did a google on my magnetic base made by Kanet and found that the indicator is sold separately. According to the pic my indicator is made in Germany.

It would appear that you are attempting to link your bearing failure to proper adjustment technique. Is it possible that there was no connection whatsoever?

Ah, but we would inevitably arrive home with the WRONG ONE

WarmBlood, would you be so kind as to tell us how your MB mechanic said to adjust the wheel bearings? Experience is always better than all the tools in the world.

Thanks

A dial indicator will beat experience every time. No amount of experience is going to allow one to "feel" 0.0004" of nominal movement.

Would that be the "I've been doing it this way for 30 years" kind of experience? You know the kind...........not based upon any solid engineering principles?

I would much rather have someone that has been doing something for 30 years using experience than a new hire, just out of school, or maybe NO school with every tool know to man. I would like to make the choice after hearing his proceedure. People with closed minds will never learn anything.

I make the above statments using almost 70 years of experience.

Both alternatives are quite possibly poor.

The fellow doing it for 30 years frequently doesn't understand the correct procedure or why such a procedure is necessary. Anecdotal evidence from many members regarding comments from "mechanics" are legendary on this forum.

I seem to recall one "mechanic" claiming to get better fuel economy at 75 mph when compared to the same vehicle travelling 50 mph. The fact that it's a physical impossibility didn't deter that mechanic from sticking with his claim.

"Mechanics" are the most close-minded individuals that I have ever met other than doctors.

Maybe he just forgot. It hasn't been 30 years but already my wife looks at me like she's wondering what she got into

Add accountants to the list.

Brian, I agree completely. But I would still like to hear his method. I WILL learn something, either he knows something we don't know or he doesn't know anything.

You know, I just typed a page about your comment about the 50 mph vs 70 mph mileage thing and then just erased it all. It is hard to explain how some one can be wrong about a subject when they have a closed mind.

There is a method in the Haynes Manual for the older (than mine) Cars that have a Washer betweent the nut and I am gessings a different type of Nut.

I don't recall the whole proceedure but at the end of it it said to loosen the Nut until the you were just able to turn the Washer with your Hand.

I went to trade School to be a Diesel Mechanic, worked at that for 18 years and and when I adjusted the End Play by hand still manage to overheat my Hub the extent that I changed the Grease in them. So apparently in my particular case my experience did not help.
In my case using the Dial Indicator fixed the problem.

Also every place I have worked there has been experienced People or Persons that were barley compatent at their Job and some how managed to stay around. I am not just speaking of Mechanics either.

If someone does not use the Dial Indicator correctly they can also not get the adjustment correct.
Typically that happens when you forget to preload the Indicator Pointer or if one or more of the Clamps is not tight enough.
The above learned from experience.

If someone adjusted with out the Dial Indicator and it did not overheat that means it the adjustment is most likely loose.

Inner bearing race to collar should have .01mm - .02mm play? Is that whats being measured?

The Front Wheel Hub is sort of trapped between the Inner Bearing and the outer Bearing. You are setting the movement that the Hub is allowed to have between the inner and outer Bearing; end play is one of the names for that clearance.

In the Pic the Bearings are circled and the arrows represent the direction of the the Hub can move.
Screwing the Axle Nut inwards decreases the clearance backing off the Nut increases the clearance.

The measurement is of the relative movement (in/out) between the hub and the axle.
