Ok my car randomly the day before xmas started to get a shake like the tires are out of balance. But its not constant and doesn't always change with speed or RPM's either. Two weeks later and my throw out bearing is making a very weird like dry door hinge sound.

I am wondering if the TB is causing me to have vibrations because its going bad and possibly starting to lock up?

Comment? I have no idea. Car seems to ride smooth as always when below 50mph.

 

Possible I think, but Id get my tires balanced before I put a TOB/clutch in.

 

I think I had the same problem with my 89 5.0 55 mph was ok but anything over made the car vibrate like nobodys business. On the way to get it checked out I popped the front universals and dropped my drive shaft. I replaced the universals and the driveshaft but it didnt help. I then replaced the rear which helped...but never really fixed it completely.

 

My gf had the exact same thing on her eclipse. We took it to pepboys and they said one of her front tires has a busted radial.

 

I have my car currently tore apart and working on replacing the clutch, which you knew. Actaully when I was driving it to the shop where I have it stored to work on, it would shake as well and obliviously mine will make noise because my Throughout Bearing is trashed. Come to find out, non of the bearings were in there contianer. LOL

Does it seem like it's jumpy?
My mechanic's were talking to me about a Tire Radial being possibley busted or was done wrong, something like that. That might be a possablity. How new are the tires and when was it last aligned?
