This is an important thing to watch for, but I confirmed I have the right
ones for this car... with 10 mm shafts, same as what I took off. I
retightened the top nuts. First I broke a hex key trying to reach the 37
ft/lb torque spec. Then I got a better hex key and tightened it til the
hex at top of shaft stripped... now it's much tighter, but never did reach
37 according to the torque wrench. If I have to disassemble it again I'll
be able to get the nut off with an air hammer, but don't know how I'd
re-tighten it. Now I've got everything back together and noise seems to be
reduced but not eliminated.
Maybe it's the exhaust system.
The hanger bracket at the transmission was rotted so I made a new one, but
the fit isn't identical to OEM. Making the bracket with the holes lined up
correctly, and gaining access to the bolts attaching it to the transmission
was a big PITA. Maybe theres a better way to get at these bolts by
unbolting the transmission mounts. It would seem the best time to replace
this bracket would be during clutch replacement or whenever the tranny is
out for some other reason. Do you have any experience with replacing it?
Thanks for the suggestion.
