Daft question: front subframe middle bolt

[ewart_hodgson]

Investigation of a clunk on my BX 4x4 estate revealed the middle subframe bolt, UK offside - that's the forward of the pair of bolts that pass through the anti-roll bar bearing - is missing. Does anyone know what size it should be, and whether there is a captive nut/ tapped hole into which it goes, or whether a nut will also be missing? This car specializes in the weirdest problems...

You must have a remarkably reliable BX! Registered on the forum 13 years ago, and this is your first post???

Why not take the bolt out from the offside and compare?

The subframe bolts are the same on the 2wd & the 4x4, or at least on the mk2 cars, so one should be easy enough to acquire. I’d personally remove the other side & get the dimensions of it & probably get a new one from a nut & bolt shop, there are some around.

I think it’s a tapped hole, I didn’t have to worry about a loose bolt on the top when I removed my subframe. The 2nd nut that holds the anti roll bar bush is shorter & has a loose bolt on top, but not the main hole. You’ll see what I mean when you look under the car.

Hope that helps.
