Just replaced the above part on my 15 year old Bosch machine – first time I’ve ever had to open her up!
The right hand spring appears to have failed due to not having a nylon bush like the 2 on the other side and eventually rubbed through on the chassis.
Genuine part was sourced locally for £13 and fitted fairly easily – it took more time to pull the machine out to do the work.
Method is to remove the top (2 screws under plastic trim and then hinges back) and then remove the back panel, several normal screws and 4 x T30 Torx fixings.
Then, to be able to pull the drum up enough to hook on the new spring you need to undo the shock at the bottom which is a 13mm bolt going into a captive nut.
Hope this helps someone in the future!
