Ok Gang, here goes...
My Amphi has always seemed noisy in the tranny. Mainly it appeared to be
a growly differential. However, recently it has taken to a weird
"chirping" noise. It has been getting worse and worse, until recently
when I was driving it the chirping sound sped up until it blended into a
hum. About that time the car started to vibrate. Throwing the clutch in
stopped the chirping sound and the hum.
I figured it probably is the tranny, but to make sure, I pulled the hub
and bearing assembly apart on the passenger side axle (seems like that
was where the sound was coming from). What a nightmare job. Bent one
puller, and bent up three of the wheel studs with the second puller. Not
to mention mushrooming the end of the axle (even with the nut on!).
Fortunately I was able to clean up the axle threads, and replace the
lugs. Anyway, the bearings are fine. Plenty of grease, and they are
smooth as can be. Guess I will put on new ones, just to be on the safe
side. Based on this side, I think the other is fine. No bearing sounds
coming from there.
So, on to the u-joints. The inner passenger side one is nice and floppy,
with no play that I could discern. The outer one is floppy on one set of
bearings but has a slight binding on the other one. Enough so that it
does not freely fall it lifted up.
I pulled the passenger side axle assembly tonight to check its u-joints.
Maybe just a small amount of play on the outer u-joint, but just teeny
tiny. No signs of binding on either on.
With the axles out, I hopped into the car and started it up. Ran it long
enough for the engine and tranny to warm up, and put it through the
gears and revs. No sound at all. I took it up to 70 mph in 4th gear in
the driveway, and it was quiet. It has always shifted well, and the
noise it makes it no limited to one gear only.
So, here we are. Are the u-joints bad enough to make this happen, and
when I throw the clutch in, the load is taken off? Is my tranny quiet
because it does not have a load on it? I double checked my axle shafts
alignments, and they are as close as I can get. I think they are
aligned.
Any ideas?
Thanks!
