<P>Simon,</P>
<P>A few years ago, I had just begun a long road trip in my BJ8 with my
son. A hundred or so miles out of town the car developed a loud, grinding,
'squeal' at the right front. Assuming wheel bearing damage, I got the
right front wheel up on a jack and did the usual testing. All seemed
normal, so I got back on the road and the noise, of course, resumed. A few
hundred miles down the road the noise stopped.<BR></P>
<P>We continued the trip--probably did 2-3K miles--and when I got home I tore
into the hub. Sure enough, that washer with the inner tab had spun and
turned about 90deg in the direction of forward travel, then stopped (the noise
was likely from the washer grinding against the inside of the hub). So,
yes, the tabs on these washers can shear and the washer can rotate. I
don't recall bearing damage, but I likely replaced both wheel bearings and
associated parts on the car whilst I was in there. If your other bearings
were in good nick I think we know what caused the problem (it's possible your
bad bearing ran dry as well).</P>
<P>I don't know if this was an original part, or it had been replaced by a
previous owner, but I blame the 'usual suspect:' sub-par aftermarket parts
manufacture. Also, I think the torque specification for the big
castellated nut that holds everything together--IIRC, it's 70lb-ft--is a bit
specious, as you have to line up a slot on the castellated nut with the hole in
the axle threads for the cotter (and you'll have no idea what the actual, final
torque is after you turn the nut to line up with the hold). Since my
experience, I always torque the snot out of that nut; i.e. I torque the nut to
nominal or, nearly as tight as I can, then put a big breaker bar on it and
continue torquing until at least the next slot (or the next, or the next
...). That is a big nut and 'bolt,' it would take a gorilla to snap it off
or cross-thread. I've had no similar issue for 100K miles or so,
though I just went through my hubs again and a couple of the bearings were worn,
but had also been run dry. This time, I sprung for (hopefully) better
grease:</P>

<P>This stuff feels--for lack of a better word--'slipperier' than petroleum
grease I've used. I have high hopes for it.<BR></P>

<P class=MsoNormal>Hi,<o:p></o:p></P>
<P class=MsoNormal>Some wisdom from the gurus please.<o:p></o:p></P>
<P class=MsoNormal>We’re looking at a MKII BT7 here. Disc brakes and wire
wheels.<o:p></o:p></P>
<P class=MsoNormal>Now, I’ve “done” bearings before and maybe did this one
wrong last time……<o:p></o:p></P>
<P class=MsoNormal>So, I took it all apart. No worries.<o:p></o:p></P>
<P class=MsoNormal>The outer bearing was completely shot. Surprisingly so as
there had been very little movement indeed when moving the wheel once off the
ground. And no “crunchiness” to the rotation. Certainly no noise or panic
inducing anything.<o:p></o:p></P>
<P class=MsoNormal>I cleaned everything off in white spirit and, once all was
pristine and dry, I gave everything a quick look. <o:p></o:p></P>
<P class=MsoNormal>See item 4, “washer”. The tab on mine had broken off in the
groove on the hub. Now, I see that this washer is perhaps better called the
“locating washer” when one is looking at the picture for the disc wheel setup.
<o:p></o:p></P>
<P class=MsoNormal>But I don’t really see what the tab is good for……surely the
washer can’t rotate once everything is tightened up, shims in situ etcetc?
<o:p></o:p></P>
<P class=MsoNormal>Can the washer have been rotating? Surely not? And could
the tab’s fracture have anything to do with the condition of my outer
bearing?<o:p></o:p></P>
<P class=MsoNormal>(The inner bearing seems fine).<o:p></o:p></P>
<P class=MsoNormal>And, yes, I will get a new washer and I’m replacing both
bearings.<o:p></o:p></P>
<P class=MsoNormal>It’s just curiosity really.<o:p></o:p></P>
<P class=MsoNormal>Thanks,<o:p></o:p></P>
