when i bought my daily the front subframe was loose (one of the encapsulated nuts sheared off inside the chassis leg... not good! means you cant do the bolt back up)
needless to say this was clunking over bumps, or if i pulled away sharply PLUS it felt drifty.
park the car up, grab each front wheel and rock it forwards and back and see if it has a life of its own!
its not too expensive to sort, my garage cut the floor pan, welded in a new nut and sealed it all back up again for £90.00
