It sounds quite bad, and if a wheel bearing is so bad that it sounds like it does (I mean, it's not roaring like a lion but it's not hard to miss, either) I'd think it would have play, too - but no. That's part of the reason for my doubt about a diagnosis. There is also a bit of a vibration from the front end (apparent front right), and I can feel it in the form of a 'bump' at very low speeds, too. Like 2Hz @10mph or so. I've no other reason to think my wheel(s) are out of balance, and besides I just rotated them and took the car out for a drive and no change, really. So I am still not left with anything better than a wheel bearing.<br><br>Also, when I rotated the tires I could see that the rear tires also have a similar wear pattern - a bit extra on the inside 1.5cm or so, slight feathering. So I don't think any wear pattern on the RF is related to the front end issue.<br><br>David<br><br><blockquote style="padding-left: 5px; margin-left: 0px; border-left: 2px solid rgb(0, 0, 255);">-----Original Message-----

Hi y'all,<br>
<br>
My tire-wear-reading kung-fu is pretty rusty, as pretty well-sorted cars<br>
mean I've not had to do any in years.<br>
<br>
On my G20, RF tire has noticeable additional wear on the inside 1.5cm or<br>
so of tread - not really severe, but enough to notice. An additional<br>
bevel, with slight concavity. LF tire has normal wear but very slight<br>
additional wear and very slight cupping on the inside inch - this is<br>
consistent with the strong left pull that I've had for a while.<br>
<br>
LF tire is not a mystery - it's the RF I'm not sure about. The car seems<br>
to have an obviously bad RF (or RR?) wheel bearing - by sound, anyway.<br>
There is the hum-roar under load, some wub-wub-wub. I need to take care<br>
of this ASAP (I wish I could do this without an arbor press, but of<br>
course I don't have one, so I need to find a place to take it to) but<br>
I'm abit unsure of the diagnosis since the apparent source of sounds<br>
can be tricky and nothing is bad enough that it is mechanically loose<br>
when you tug on the wheel.<br>
<br>
Tie rod ends are probably OK but I think I'll replace them soon anyway.<br>
Front end feels fine in terms of tightness but it's got 165k so it won't<br>
hurt. Tie rod ends car cause toe issues and related wear, but the wear<br>
on the RF tire does not suggest toe to me due to the pull to the other<br>
side.<br>
<br>
Thoughts?<br>
