Here is the deal.. I guess it's not to bad..... I have a 99 SS.. OK when I get on it and shift hard into second or third it sounds like the rearend or drive shaft hits the floor or something??? So I jack my car up and look and my drive shaft has dents in it around in one spot.. It is about where the Ebrakes mount underneeth.... Anyone know what is cousing this??? Shocks??? This is my first camaro and I love it just trying to fix this prob.. THANKS!!

 

Maybe you have a loose/broken tranny/motor mount(s)...

 

Ill check that out.. But It is hitting near the rear of the car..

 

tranny mount is my guess, dealership part or buy a poly one. dealership one is like 70$

maby the tq arm is loose like bigtime?

 

Moving this to the newbie section...

 

My guess is tranny mount too. Got an pics? Maybe a pic of the underside with the dents on the driveshaft circled? Pictures are worth a thousand words...

 

and remember, you usually have to take the trans mount OFF to check the mount. it could look perfectly fine and be torn to hell (like mine )

4 crossmember bolts (15mm), and one 18mm deepsocket for the mount itself and the crossmember comes out. make sure to have the trans supported when doing this or you will have a mouthfull-o-t56

from there its just 2 bolts to remove the mount from the tranny.

 

You maybe experianceing what i was till it mysteriously went away after an hour drive. Do you take corners fast? Check you lower control arms and panhard rod bar, along with torque arm. Also remove the rear carpet to see that the rear shocks bushing is seated correctly through the hole.

 

I should mention that the dent on the driveshaft could alone be giving you the problem, since the driveshaft may no longer be balenced.

 

Is'nt the Handling and Braking section a better place for this?

------

Back on topic:
My guess would be tranny mount or torque arm. Also, if the drive shaft is dented, it may now be out of balance or bent enough to cause vibrations.

 

Or gears and axle section.

 

Yeah that too.
