Just had the rear subframe replaced on my SLK 200 following a scary moment on Monday when a suspension arm let go exiting a roundabout. Picture below of old subframe!
Dealer depending, some will sort for free, others not.My subframe gave up the ghost this week after 15 years. MB dealer says that there have been almost 500 subframes ordered for these cars so these are not isolated incidents. MB should bear some responsibility for the poor quality of a major structural part of the car and offer free replacement part or free labour to fit new one. Someone will be seriously injured one day if this is allowed to continue!
It does corrode both ways, but you can see the outside.What I would really like a look at, is the MB inspection document for the rear subframe, then I could look at my own car, and make a decision myself, whether it's done free of charge or not. I don't want to replace it if it's OK. But would get it replaced, if it has a problem. Does it corrode more from the inside out ??? Are there any critical points where no corrosion is allowed??? Is there a Mercedes service bulletin for this procedure ??? Any info on this would be greatly appreciated.
Having looked at mine for the last 2 years when up on the lift at MOT/service time, there are some small areas of corrosion, that I have "waxoyl"ed, but nothing major noted. But I haven't had a boroscope down the inside of the subframe yet.
I'll be interested to hear how you get on. Considered similar myself.Having just bought a Bosch "inspection camera" (GIC 120C from Screwfix) to inspect a bathroom shower leak. It could be the ideal tool to inspect the inside of the subframe at the next opportunity.![]()
We (I) started one, but nobody bothers to contribute.is there not a list of main dealers that have agreed the work under goodwill as maybe everyone should just turn up on there doorsteps and drop there cars off with them, i struggle to understand why one will do it free of charge but others refuse, on my last mot i asked my mot guy to check my subframe and he said there was some slight corrosion but nothing to worry about, but im not convinced
Strictly speaking it should be in the UK repair shops section.The sub frame post on the dealers is not easy to find.
just having mine done at inchcape free of charge apart from them replacing the rear brake pipes while there at it, can`t really expect them to pay for that
