[Amc-list] Droning American

["Jay" <jciampi@xxxxxxxx>]

Well guys, today I started check out my driveshaft and wheels for problems. 
I found the LH rear wheel had a wobble from being hit sometime back 
(previous owners). It wobbled about 1/4 to 3/8 inch . I swapped it with the 
spare rim, put the road tire on the spare rim and re-mounted it on the car. 
Better!   That helped reduce my droning and vibration even more.
I watched the driveshaft wobble a bit at idle speed (in drive)  with the 
wheels off the ground. With my buddy watching the drivehsaft, I revved the 
engine up to 40-45 mph and the vibration showed up along with a noticeable 
wobble in the driveshaft. Funny thing though, when the vibration was more 
noticeable in the car, the driveshaft actually looked like it reduced its 
wobble a bit.  Strange!
I did hear a squeaking noise coming an going around the rear U-joint. The 
U-joints are new, but the yokes are not. I think I must have a bad yoke in 
the rear. I am going to have the driveshaft repair folks in Lakeland, FL, 
have a look at it in the next week or so. The car is actually getting to 
drive as good as a new one now. With a balanced driveline shaft and yokes, 
it should be great!

More later
