Ok, it's a 2002 base rsx. All stock, no mods. The passenger side wheel
has been making a speed related thumping noise for a while, more
pronounced while turning left than right - I think it started when I
replaced the tires about 3 weeks ago, but it may have been doing it
before then - the old tires were pretty bad, and I may have dismissed
odd sounds.

So I took the car back to the place that replaced the tires, and had
them rebalance everything, and check it out, and rotate the tires, and
they said they thought the wheel bearing was bad. The sound is still
coming from the same place after rotating the tires. They couldn't
replace it right away, but guesstimated a price around 300$.

Does this all sound right? Is 300$ (US) about right? Should I have this
sort of thing done by the acura dealership, or can anyone do it? For
that matter, is it something I could do - any special tools required?
(No bearing pullers here, but otherwise I'm pretty well equipped) How
long do I dare drive this thing before getting it done - money is a bit
tight, but if it needs to be done pronto, I can find a way?

Thanks for any info!
