Cracked rear subframe ........prob gonna seriously cost!!!

[Russboy]

Not sure for the exact terminology but calling it a rear sub frame for now. It’s cracked all over the place on both sides.

Basically my mate suspects that the H&R anti roll bar has prob stressed the rear sub frame and as such I now need a new one!! There are two options get a new/second hand one and fit it, or strip this one out, weld it and put it back in.

Which ever option I am forced to choose we will weld a cross section or two to strengthen it up.

Anyone know if it's a common prob?

What models of Audi's will share the same part so that I can broaden my search?

What am I likely to pay for a new one from Audi? (My mate works for Croydon Audi so is researching this for me)

Here’s the pics:











Any info/advice most welcome

Yes, this is a well documented fault Russ. MRC sell a strengthening bracket now because they'd seen so many cars with cracked subframes. From the looks of those pics, you might be better off getting a 2nd hand unit rather than repairing that.

A few people have tried contacting H&R about it, but they've apparently stuck their heads in the sand. Knob jockeys!

Hotchkis and Neuspeed ARBS come with integrated subframe support brackets. They've obviously realised that the subframe is a weak point. Makes you wonder why H&R haven't picked up on it.

Any idea what sort of £££ i'm looking at for a new subframe?

Never heard of one cracking there! Looks dangerous being the wishbone locating bolt. I'd get that changed ASAP, wouldn't even consider welding it.

Mine went there and I coughed up and bought a new one from Vagparts!

I've done several like that . I've replaced them with good second hand units .

Didn't realise it was the ARB bracket, looked like the wishbone mount at first glance!

Mine was completely broken on one side - just hangling loose torn right through the rear toe fixing point.
Managed to weld it though; fortunately being the offside was quite easy to get to without taking the sub-frame off.

Then I took it to MRC pretty sharpest to fit the stregthening brackets - they thought my welding was ok.
