1 heavy recommendation "almost a fail"

also this is a little more important on the way to the MOT I experience the clunk clunk clunk on a rear CV joint this has only ever happened for about 10 minutes a year or so ago, I want to repack the CV joints with grease but I can remember if there is a way of doing this without removing the drive shaft from the gearbox? any ideas on this too would be gratefully received.
I know I havn't been on here much since november but all I have done is started him up about 4 times in that period. looking forward to camping in a couple of weeks I think the children cant wait and my wife cant wait for me to take them away so she can relax once in a while again.
