There was a noise, a "roar" from the front end of Oscar that I thought was the wheel bearings going out.  On the straightaways, the roar was there, and turning left on a curve, the roar went away.  I took the hubs off and the left outer bearing had a "grind" to it when I spun it.  I had new wheel bearings all around, so I replaced them all.  The drive to the meeting tonight was the test drive, and wouldn't you know it, the roar is still there.

Now, if the inner race on either bearing is turning on the shaft, will this make a roar?  I read in the Bentley, that the inner bearings sometimes will turn on the shaft and if they are turning, the tap a center punch where the race seats on the shaft so that it won't turn.  But of course, I didn't do that.  The hubs slid back on without much effort, and now I think that the races might be spinning on the shaft.  As far as adjusting the bearings, Bentley says .001 to .005 inches on the bearing play, and I set these with a dial indicator on a magnetic base.  I didn't, but should I have set the play with the road wheel on the hub?  Is there a possibility that I really didn't set the play at what I thought I set it at?  And could this be the source of the "roar"?  Tune in next week when you will hear Robin say, "Holy clampnuts, Batman!"

@%$&!  :evil:

(And David, the mysterious "creak" I was trying to get you to hear tonight from Oscar's rear end started back up again...of course, only after I had gone down the road a bit!)

The drive to the meeting tonight was the test drive, and wouldn't you know it, the roar is still there.

Drill some holes in your muffler.  You won't be able to hear the noise.  If there really is something wrong, the problem will eventually get worse and become obvious.   :whistle:

Lo and behold, there is dusty rust (or is it rusty dust?) on the rear axle nut on the driver's side.  A little, but not as much, is on the passenger side.  So, what is that dust?  The bearing disentegrating?  Pixies livin' in there?  :?

When I got the rear jacked up and supported, I put my hands on 3 and 9 o'clock on the tire and wiggled...a little rockin' going on.  Then I put my hands on 6 and 12 o'clock and wiggled...quite a bit of rockin' there.  
The driver's side is more noticeable then the passenger side.

I also rechecked the front wheel bearing adjustment with the dial indicator and had to tighten the driver's side about .001 inch.  Still, not that much to make any difference.  But now I know just about what .003 of an inch of wiggle feels like.

Ok, went to take the nut off the shaft on the driver's side and while removing the cotter pin, the nut started to turn!  It was VERY loose!  Took it off and pulled the hub off (thought it would come off easy, but had to ease it off with a puller).  Splines appear to be ok, just dirty.  When I get all the dirt and old grease off of there, I will have a better picture.

Wasn't thinking, and had both rear tires off and the bus jacked up when I went to the other side to loosen the axle nut...what do you think happened?  NOTHING!  I had to put the hub back on the driver's side, put the drums and wheels back on, lower the bus, put on the E-brake, put it in gear (the bus wanted to roll with just the E-brake on) and then go to loosening the passenger axle nut.  It was NOT loose!  Got it loose and called it a night at 2:30am.
 

Wouldn`t be a bad time to pack those bearings.

I don't wanna!  But I will do so.  It just scares me to take the bearing housing off of the spring plate and swing arm (is that what it is, I don't have my manual with me in front of the computer).  It scares me only because I have never done it before.  But then, I was reluctant to do the front wheel bearings on Sweetpea that first time many years ago...and found out it wasn't that bad.

Got to get some sleep for the Herbie movie...don't want to get my sleep during the Herbie movie.

The axle with the nut that was loose was essentially dry on the splines.  When I took the other hub off, there was some grease on the shaft that, I swear, looks blue.  At least it has a bluish tint to it.  And it smells...almost a "burnt" smell...the smelly smell that smells smelly.

One more thing.check the spacer thats on the stub axle where the hub tighten up on and you will see a wear ring most likey. If excessive , replace it if you happen to one laying around.

Just so I don't trip on the stones on the garden path, I see in the manual that the spacer ring is on the '68-'70, but they don't show one on the '71-'79 buses.  All years (in my Bentley) have a spacer sleeve between the roller bearing and the ball bearing.  Looking into my rear housings, I only see the edge of the roller bearing...no spacer ring.  It looks like the hub butts up against the roller bearing.  And again, just to be sure, the picture shows on the '71-'79 (from outside to inside) an oil seal, circlip, roller bearing, roller bearing race, spacer sleeve, ball bearing , circlip, and oil seal.  All are on the stub axle, with the exception of outer races (pressed into inside of housing), oil seals (pressed on either side of housing) and circlips (which look to be in a groove in the housing).  

I have both hubs off now and am going to start working on the "dry" side.  I think I can do this.  I think I can...I think I can...I think I can. :thumbs-up:

(This post started out with questions on front wheel bearings.  It has morphed into a discussion about rear wheel bearings.  Funny how that happens.)

Travis, The inner race of the flat roller brg will slide out of the rollers . Be careful because the rollers can fall out also and they have a nasty habit of sneaking off into the sunset not to be seen again by Man or beast. Belive it or not, the sleeve between the bearings is the easiest piece to forget to re-install. Don`t know why. As far as the spacer, thats the reason I said to check your manual. You don`t work in that area very often,so you tend to forget the subtle changes. I do. It looks like you are on the right track and doing fine. Just go slow and don`t forget anything. When you re-stall the axle nut, tighten it as tight as you can get it and then go some more . :lol:  :lol:

Travis, I have never seen a clip on the outside of a Type 2 or a Type 1 for that matter.  The 4bolt ret. holds the O.S. bearing in place.
  F.Y.I.  Your IRS Bugs have the same set up on the rear bearings except they have the spacer your Type 2 doesn`t have.
  Your bearing fell apart because It was worn out.  If you pack your new roller brg. and keep the inner race in place, you can install it without a driver. They go in without much problem. You will have to keep an eye on that inner race when you "Knock" the stub axle back in. It will want to slide out . Just "peck" it back in as you go.

Hey !  Good show. What horror story ? Its just nuts and bolts and asking a few questions. Using proper and correct parts other than trying to adapt  Maytag stuff works pretty well. The worse part of this job for Homecrafters is getting the axle nut tight enough on a Type -2. There a`int  nothing like a 2 foot long cast iron hammer wrench after the impact wrench runs out. :lol:  :lol:
