<VV> VirtualVairs Digest, Vol 182, Issue 15

[Hugo Miller]

Yes, for sure the tires are causing the vibration - or most of it, 
anyway. But they are not making my axle shaft wobble! The reason I 
posted on here in the first place was simply to find out whether there 
was a common cause for play to occur at the inner end of the axle shaft. 
I don't want to sound ungrateful, but I wasn't pleading for somebody to 
come & sort the problem out for me - I can do that for myself!
All I was trying to do is establish whether this was a known problem 
with a known solution or not.
Now, it APPEARS that the problem has gone away, now that the car is 
back on its feet. But certain people (I'm not being diplomatic - I can't 
remember who it was!) have suggested that the problem is simply being 
masked because there are now forces being transmitted from the tire to 
the shaft, now that the weight of the car is on the tire. I am about to 
get underneath with a lever and put this theory to the test. Just to set 
myself up as an aunt Sally, I will say here and now that I am not 
persuaded by this theory. But be assured that if I am wrong, I will come 
back and admit it.
