When you say "same area in time with RPM" I assume you mean with the rotation
of the wheel rather than the engine? And that the noise continues even if
you disengage the clutch while turning with the noise. Going on that
assumption:
From my experience the Cv joint makes a knocking noise rather than a clicking
noise. I'm not trying to be as jerk (I come by it naturally) but is it more
of a knocking or a clicking? Mine bad CV sounded like someone drumming a
finger tip on a solid desk top. If it's truely clicking I'm at a loss as to
where to look.
The origin of noises can be elusive. Joel Walker made a good suggestion to me
a while back which is to have someone sit in the back and tell you where the
noise is coming from. Perhaps you've done this. But what I'm eluding to is it
may be the driver's side CV joints but it sounds like it's coming from the
passenger side. In the scheme of things the two inner CV joints aren't that
far apart, as in right or left side--they're just the width of the
transmission apart. So that must be something like a difference of 8 inches
or so from the center of the bus assuming the trans is about 16 inches or so.
To share my experience my CV clunked when I started from a dead stop
sometimes--not always. And I SWORE it was coming from the front passenger
side wheel. The CV later started knocking on the passenger side. When I had
my buddy sit in the back he said the clunking was coming from that passenger
side rear wheel as well as well as the knocking. I couldn't believe it
because I was so sure it was up front in the front wheel. I replaced both
passenger side CVs which had serious pits in the balls making the diagnosis
easy and the problem was solved.
For what it's worth my CV knocked the most when I made a hard right
turn--especially on a highway off ramp that curved right. And the problem was
the passenger CV joints. So it was the side on the inside of the turn that
brought the most knocking.
I don't know if this is the universal experience with CVs. Meaning I don't
know if you can diagnose the side by which way you're turning and the noise
it creates. Which way turning creates the most noise on your bus?
That's about my extent of knowledge or information on the CVs. If you have a
clicking instead of a knocking I don't know what you should be checking.
Hopefully another listee has some ideas.
Good Luck
