hi all weather permitting ill be doing both of the rear cross member bushes,all I'm gonna do is jack up one side at a time undo the large bolt holding the bush in place then undo the two smaller bolts holding the bracket on then hopefully prise the old ones out,push the new ones in using me trolley jack probably coat the new bushes in copper grease so they go in nice and easy.
any pointers or any easyer way I'm all ears all the best harry

If it's a b*stard then use some threaded bar, two nuts and two suitable washers, then just wind it through till the bush pops out

                                                 i think these have been in the car since it was built
