Welding to the subframe.

Just replace the whole part. Check/replace the transmission mount while you are at it.

If TIG welding a lip is strong enough, there's no need and would be a lot quicker, cheaper and easier.

If it's not, then I'll look at replacing it.

The TIG weld will be strong enough but you'll still have to remove it, plus clean it up and as it's a thick part it will need to be pre-heated too before welding. Easier to just swap it out.

Strange. The garage told me that it could be done on the car, but the arm would need to be dropped due to melting the rubber bushes...

So it has to be removed anyway?

Looks like you have a nice new track arm there. You replaced that - why not the subframe half?

Yes it can be welded on the car.

Porsche intended this to be replaceable if damaged. I'd follow their lead.

Again like I've mentioned above, welding is the quickest, easiest and cheapest route to go down. Once done, its function would be identical to if I just replace the part, except it'll be a lot less hassle. It's not on show, it doesn't need to look perfect. To change the subframe part I'd have to have a transmission jack followed by a lot more patience/difficulty, and whilst I'm comfortable with doing a lot of suspension work myself, I'm not comfortable doing that. Changing the arm took me all of 20 minutes and was two bolts, so that's no comparison.

If welding is strong enough and can be welded on the car, there's literally no reason for me to change the part at this time. I may change it in the future for the sake of replacing a part so that it's as it should be, but it'll hopefully make no difference after I've welded it. I'd just be doing it for the sake of it.

Just needed to know if it can be welded whilst on the car and if it'll be strong enough - looks like a yes to both of those. Thanks guys.

Want quick, easy, and cheap? Grind a fresh surface for adhesion and J-B Weld a small strip of aluminum on. J-B Weld can fix everything.



Want it done right, safe, and permanent? Replace it.
