Subframe

[Kioun]

Hi,

My vehicle failed MOT on the subframe and ultimately needs a replacement.
Will a mk4 or mk5 fit into a mk3 at all? Maybe with some adjustments?

Thanks

Has it failed on just the front subframe horns?
If so they are not too hard to replace if you can find some.
I think Minormatt is breaking a Mk3 SWB now or soon, send him a pm.
I've never done it but if you do go down the MK4/5 subframe route, the Mk3 shocks need modifying at the bottom fixings and you'll need new Track rod ends plus whatever else you come up against.
Good luck

I've not spoken with the garage in depth, but apparently there's holes in it and not a welding job.
Good to know it's not impossible to fit mk4/5 as I already know someone breaking one.

Next question though, is mk3 subframe the same on petrol / diesel models?

[Keef]

There's only one part number for the Mk3 front suspension frame (Cross member assy - front - 11/85 - 8/91 Finnis 6149187 - Part # 86VB 5019 AC) so I assume they're the same.
I've known the front horns to rot and also the wishbones but never the frame itself.
Get under the van with a torch, the garage should have marked the failure points with chalk.

Yes I'm with Keef have a look, and pretty sure they are the same on petrol and diesel and probably wishbones/horns very unlikely to be the main section.
