[TR] TR4 wheel bearings?

[Tim I. Purdy]

Bingo! Though live about 90 miles from the nearest freeway. I took a friend 
on a short drive, and once at a steady speed 55 mph or so the sound dimmed. 
Now, I have never undertaken something like this. Parts availability does 
not look good either, or can get some from Moss, others not listed, would 
Napa Auto Parts have a suitable replacement.?
