car shakes over 45mph

[Htownsvx]

well i dont realy have a clue whats going on but i think it has something to do with the tranny but i hope not i just spent $3000 to fix the thing.

the car drive fine untill you get over 45 mph and the you can feel the hole car shake. last night i went to get some food and at like 30 or 35 mph it sounded like drive shaft or something right onder the center conscol was hitting something it was like a tapping sound but it was not a loud sound i had to turn down the radio and the heater to hear it

go underneath your car and check that area between the cross member and the tranny... If everything seems to be in order then you have a bad wheel.

I had a bad shake one time too in my Silver (why did I sell that) and it just needed tires balanced.

But with someone just being under your car......I don't know.....doesn't sound good.

Keep us posted please.

You should take it back to the shop that serviced the transmission, ASAP.

and if it's a bad CV Joint you tell them it's their fault its busted!!!

Is the driveshaft rubbing on the heat shield? Perhaps the U-joints are worn in on the driveshaft?

[Htownsvx]

if the ujoint is bad how much would it cost? and would it be some easy to install or should i take it to the shop? and will i need a special tools for the job?
cause my idea did not work and i have noticed that when you brake you hear a popping untill you come to a stop but its not a loud popping, and when you brake hard some time the first pop get louder.

but im the guy who hate to take it to the shop unless i really cant do it

[Earthworm]

That's the catch...the U-joints were not made to replaced although some claim to have found ways around this.

so then im looking at replacing the hole drive shaft????
