is your car lowered at all? If so your pinion angle may be off. I know mine is because I get viberations up around 75mph so I need to make make upper control arms adjustable to stop the viberation

I see now what you're saying. Sounds like I may indeed have two problems to check. Regarding the wheel bearings, when I replaced them, I had just done struts, so I brought the car in to a shop for an alignment check a few days later. They told me that the wheel bearings needed to be tightened, so in a way, I kind of DID get them re-snugged (is that a word?) after only a few miles (I'd say it was probably about 200...perhaps that's too much?). However, that's not to say the spindles aren't damaged... I'll have to look through my log book, but I thought at one time a few years ago I replaced the caliper hoses, but I may be thinking of my T-Bird instead.
 
I will check the tailshaft bushing and let you know if it's got play. I'd be interested in using the "super secret" method if I'm allowed to discover the "secret"! :D
 
Thanks for all the detailed information. I will be printing this thread for reference! :)

Nope, unlike your much cooler - looking car, mine is completely stock ride height.

BTW, I'll be on vacation to WI for a bit over a week (starting tomorrow), so I won't be able to check any of this for a bit...stay tuned.

tailshaft bushing install "for cars with original one

hacksaw off about 1/2'' of your new bushing.
file the minor edges off
slide it on your yoke
start your yoke up onto the transmission output shaft
slide in yoke until its all the way in

***at this point your yoke is being stopped by the new bushing

pull back on yoke and forcefully slide it back in a couple good wacks.
the new bushing will begin enter the tailshaft housing of the trans.
the new bushing is pushing the old one forward
keep the "slap hammer" effect of your yoke going until the bushing is in
it may stick out a hair or two but thats fine.

the old bushing is still seated but has moved forward.
there is pleanty of room up in there to accomadate the two bushings.

Position the bushing corretly if it has a weep hole (downward) before isntalling.

the bushing "kit" may come with a seal as well which will raise the price a little.

all in all, a 15 dollar fix.

jcassity,
 
After reading thru your post regarding the "popping & squeak", I think I also have a k-member issue.  My car is a V6, so I gather that the cross piece that you removed is NOT on my car?  I wouldn't be surprised if my CA bushings needed replacing, as well...
 
I don't have the tools to do all this myself so I suspect I'm going to have to go to a shop if it is a CA issue...
 
Still going ot check the tailshaft bushing, too!
