Silly question: On my Mk4 Mondeo the rear lower wishbones are well corroded (no MOT comment though) and both springs now chipped (with MOT advisory). Corrosion looks the worst directly underneath the springs.

My health no-longer lets me play with stuff like this. 

I've used a great Ford dealer who has sorted many other issues with the car (that I've only had a few years).

Both that dealer, and my best local tyre fitter (that also does suspension) don't want to change the lower wishbones as the Cambolt adjustment is set in the factory using a factory jig they don't have. You also read stories of cars that have had the wishbones changed and no-longer steer/handle correctly.

Aside: Assume the cambolts will change the rear wheel camber and also possibly the rear toe in (Cambolts named after lobed Cams ? though - like the things in your cylinder head?)

How then do I get the wishbones changed?  or is it just not sensible.

Hmmm - what about putting the laser jig on the wrong way round (front jigs on back wheels) - or does nobody know the settings?

I would like to get this fixed before the springs break, and do two jobs in one - springs and lower wishbones

I'm off now to wax the paint damage on the springs, and think about painting the wishbones (probably not a sensible idea - better to paint the rear subframe rust first)

Many thanks.

 

Similar situation with the rear camber bolts on the Mondeo mk3,  they're a special cranked bolt, and really need some tlc to remove them. For starters getting a rotary wire brush on the exposed threads then plenty of oil. Also, mark the position of the head of the bolt (not the nut) so use a centre punch to make a dent in the side of the bolt and another in  the chassis, so when you turn the bolt, you can rotate it back to where it was (bit clumsy, but know what I mean?)

Use 6-sided sockets on both nut and bolt head, NOT 12-sided ones. else you'll round them for sure. I've read a thread where someone managed to remove the old and fitted new camber bolts n nuts, I'll look for it and put the link here, but meantime, I've successfully removed really stubborn nuts by heating them on hottest setting of a heat gun for several minutes first.

This guy had no luck, I'm still looking.

See if you can find anyone using a Hunter alignment machine and ask them if they can align it after replacement.

You'll often find them at accident repair centres.  Although large Ford dealers and some KwikFit centre's also had them last time I checked.

Here is one link - I am sure there is more info somewhere but I can't find it
