Ford Transit 2006 Problems

I haven't heard of it before, but I reckon your mechanic is on the mark when he says it's the turbo. I would have the turbo checked for sure.

It sounds like an alignment problem, or a problem with the suspension collapsing and throwing out the alignment. You need to have it checked by a suspension specialist.

If you are not sure about the van you're buying then back out of the deal while you have the chance. The next time you decide on a van have it checked by a mechanic.
