Rear subframe options
breeze:
The rear arms are being replaced on my Golf and the mechanic (I did the front, not this time) has pointed out that the rear subframe is looking a bit crusty. Not terrible, but it would be a good time to do something about it, since it is all down. His suggestion is to give it a paint.
Any advice? Will any FWD Golf MK5 rear subframe work?
Are any of the rear subframes on other cars interchangeable, like perhaps an aluminium option from another model on the same platform?
Grateful for thoughts.

A job I'm planning but dreading doing this winter. You can get aluminium ones that will fit but this will mean cutting the wheel well off to fit as they were for 4wd variants.
I've always wondered if the mk7 and mk8 rear subframes fit as they look identical.
Personally I'm planning to clean up a bit and apply a rust converter/paint. It's thick steel so should all be surface rust.

Buy one off ebay and get it prepped & powder coated ahead of time, then just sell/bin the one that comes off your car.
As above, no one in their right mind would chop the boot floor away for an alloy subframe with minimal to no weight savings, unless going 4WD.
Yeah it is proper beefy steel and the rust is worse than it looks. Mine has never even had an advisory on it, and I know for a fact my local tester gives everything under there a hefty prod with a pry bar!

Yep rust was better than it looked. He’s been using a wire wheel and actually it looks quite good now. Plan is Bilt Hamber Hydrate 80 and then paint/stone chip.
It should be quite presentable when done. An aluminium option would have been nice, but I couldn’t find anything for FWD cars. Also a bit unreasonable for the mechanic to expect my car to sit on a ramp for a few days to wait for parts.

Nice! I don't fancy leaving my car on axle stands for a week while I do mine as its a bit of slopey sketchy driveway so I'm still debating whether to do as you did and get someone with a lift to do it or just get a spare and powder coat is as Pudding said and just swap it out in a day.
