Hi, I have a Hotpoint CTD40P tumble dryer. It makes a louder and louder noise as it warms up and even a worse noise when the drum reverses. I found it had worn bushes so I got a bearing kit and replaced the back bush and shaft and the front wear pads. It is still making a lot of noise. Especially when reversing. The whole machine vibrates and causes everything to rattle. How can I solve this?
