Subject:      Transmission MainShaft Needle Bearing Noise
Content-Type: text/plain; charset=ISO-8859-1

Hi all.

A Vanagon mechanic listened to the growling noise in my newly
installed transmission. It's audible under load in 1/2, but not 3/4,
likely due to louder ambient noise at higher speeds. (or ingrown ear
hairs. <grin>) Noise is a little quieter than engine.

Mechanic said "input shaft bearing" and kindly pointed out the part on
an open WBX transmission. My Long Enterprises CD calls this part
"mainshaft needle bearing". Bentley calls it "needle bearing" and
shows it on mainshaft. (35.20 and 35.49... just for clarifications
sake) Seems to me the worn bearing is allowing some other part(s) to
actually make the noise.

I understand pulling transmission sooner than later is best but.....

If someone else has had this noise and/or diagnosis, how many miles
did they drive it like that?

Would this noise indicate a failed needle bearing?

Running Redline MT synthetic if that figures in.

Much thanks,

Neil.
