judder in 1st and reverse?

hiya peeps im in need of some help i have a 99 freelander xedi, i have recently had a new clutch, it used to judder befor the new cluth but only on hills and reversing around corners occasionaly, but now for the last month or so it does it nearly everytime i pull of or reverse i feel it in the rear wheels and im concerned its something major, the garage that fitted the clutch seem to think it might be the fly wheel needs skimming but i dont want to fork out for that if thats not what it is any advise would be awsome thanks

check out the rear diff front mounting first

thanks freelance will do and will keep you posted, have you ever changed sunroof tracks on a freelander? i was thinking or having a go but a few people have said its dificult and to leave well alone!!
