I just had my oil changed yesterday and I noticed today on my way to work that my car was making a clunking sound like I was going over potholes when I slowed down. I have a stick and I beleve it happens when I'm in higher rpms and and slow down but it didnt do it when I was going down hill, and when I tried to replicate the noise in a higher gear and it lasted longer before it was about 3 clunks then it was about 7 in higher, anyone have any ideas? thankyou for reading

 

Your post is a little vague in detail, but just to give ideas,
brake pads on some vehicles will make a simular noise if
worn out, and are applied heavly.
Need a lot more detail............

 

Is the clunking seemingly related to engine speed or is it more of a random thing? Have you checked the oil level?
