i recently bought my car and the first thing i noticed is that when you take off and some times when you shift it makes a clunk noise and feel at the way back of the car dose any one have a clue what this might be

 

clunk in the rear end when you shift huh? sounds like a diff mount to me. have fun replacing it, i hear its a pita.

 

Sounds like a broken differential mount. The mount runs for about $130 from the Mazda dealer or something like $60-70 dollars from Mazda Motor Sports. Do a search for Differential Mount and you will find lots of good info on where to buy it and how to replace it yourself. Good luck with your car and welcome to the forum!

 

thanks
