tire wear, wheel bearings

[David Pertuz]

Hi y'all,

My tire-wear-reading kung-fu is pretty rusty, as pretty well-sorted cars 
mean I've not had to do any in years.

On my G20, RF tire has noticeable additional wear on the inside 1.5cm or 
so of tread - not really severe, but enough to notice. An additional 
bevel, with slight concavity. LF tire has normal wear but very slight 
additional wear and very slight cupping on the inside inch - this is 
consistent with the strong left pull that I've had for a while.

LF tire is not a mystery - it's the RF I'm not sure about. The car seems 
to have an obviously bad RF (or RR?) wheel bearing - by sound, anyway. 
There is the hum-roar under load, some wub-wub-wub. I need to take care 
of this ASAP (I wish I could do this without an arbor press, but of 
course I don't have one, so I need to find a place to take it to) but 
I'm  abit unsure of the diagnosis since the apparent source of sounds 
can be tricky and nothing is bad enough that it is mechanically loose 
when you tug on the wheel.

Tie rod ends are probably OK but I think I'll replace them soon anyway. 
Front end feels fine in terms of tightness but it's got 165k so it won't 
hurt. Tie rod ends car cause toe issues and related wear, but the wear 
on the RF tire does not suggest toe to me due to the pull to the other 
side.

Thoughts?
