I have a 1983 gsl and I had a bent axle and rear end that was messed up. Sounded like a rattle can.... A friend let me use a spare pumpkin out of an 84 and an axle, everything fit fine with no vibrations or rattle. The problem I have is when I slowly release the clutch my car begins to shake dramatically until 1st is fully engaged. The same happens from a stop into 2nd. Do you think the disc could be worn? It did not do this on the previous rear end. I changed the driveshaft to a larger. Added LSD fluid And additive. I apologize in advance for the grammar, I'm on the cellphone. Nick

 

Did this start after the installation of the new rear end parts? These symptoms are classic indicatin of a flwheel that needs resurfacing, but if it started after the other parts were installed then you could rule that out.

 

You sure its not the clutch?

 

Sounds like a clutch issue to me. Maybe oil on the pressure plate or worn clutch.

 

Trans mount separated rubber from steel. Motor mounts are also probably sloppy.

 

This sounds more like clutch shudder rather than wheel hop, which is something you get when the tires are spinning.

 

does it only happen when hard launching? if so then yes its wheels hop if not then its something else

 

I will do some more research and have somebody watch it all, thanks for the ideas so far. Ill tell you what I find.

 

Like peejay said it's clutch shudder but like I said it's caused by a bad tranny mount. Jack it up and see if the rubber is coming away from the steel.
