[TR] what's that noise? update

[Anthony Rhodes]

I had an odd noise in my 4A IRS which turned out to be a slightly loose brake
mounting bolt.

As for u joints, when I bought the car the driveshaft had a bad vibration
which appeared to be bad phase alignment if the 2 halves.  When I corrected
the alignment of the yokes, the vibration was unbelievably worse.  The front
ujoint was demolished and had bots and pieces of the rollers inside the cups.
After that I had a very slight vibration.  And I checked the other 5 ujoints.
One had a noticeable click when twisted by hand.  It was also in terrible
shape.  Then I really tested the others and one had the most subtle click.  It
too was bad.  The others seemed ok, but I replaced them anyway.  It turned out
that all but one were really on bad shape.

So don't discount the possibility of bad  but in my case they created a
vibration, not a noise.
