Ok, thanks. BY CARRIER BEARINGS I mean the bearings for the stub/flange
that sticks out of the transaxle that the CV's mount to. I can get OBD 2
readouts on my phone. Just haven't done that yet. Tonight perhaps. At 70
mph the tach reads 4000 rpm. 70 MPH IS THE MAX I will ever drive it. 60 to
65 in most places. I'm not in that big of a hurry to go anywhere at my age.
eVENTUALLY i will install a temp gauge for ATF temp monitoring. As always
if you own a Vanagon it's an ongoing project.
