Mark,
If you could clarify your description of events I may be able to help!
<Hi guys, on the way back from Mid Ohio's Sprint Vintage Grand Prix and
LBC Show yesterday, my car developed a grinding sound when in gear.>
Did you put the transmission in neutral while moving, (25 MPH or more),
and the noise stopped? I assume that when you say "in gear" you must
have tried free wheeling in neutral and the noise disappeared? Maybe
not?
<1st note:>
<"I don't seem to have a wheel bearing issue, both rear wheels seem to
be spinning clean". So I double, triple and quadruple-checked the jack
Stands, started the car and put her in gear (1st). The grinding is very
noticeable.>
2nd note:
<Guys, does this make sense? I took the rear wheels off, and the first
thing I noticed was my right rear seemed way too tight.>
Mark,
This reads like a contradiction! Do the rear wheels spin freely, or is
there an obvious problem? What was too tight?
<2nd note:>
<So I adjusted it back, and with the wheels off, went back to my
investigating. In gear with the wheels off, it's pretty quiet. I don't
hear the grinding anymore.>
What did you adjust?
<So I put the wheels back on, and took the car down the driveway. As
soon as I got back in gear, the noise was back - sort of a grinding
popping sound, like when gears aren't meshing properly.>
Gears submerged in oil, and surrounded by a casing will not produce
horrific sounds! They can certainly fail! Metallic grinding noises? No!
Dull popping, more felt than heard? Yes!
<On the way home, shifting still seemed smooth, and I have all gears,
Including OD and reverse.>
My conclusion,
It is unlikely that there is anything wrong with your transmission!
Best regards,
Jim Swarthout
