Thanks again Griff, I've been told it can be done in-situ but it looks like a pig of a job. I thought it was a uj gone but had the prop off and the uj's are fine then I noticed some play in the output shaft this causes vibration when you put the gas down, hence I thought it was the uj. I've always had a bit of vibration thought it wer because of the Evo lift kit so forked out for some scorpion robbing extreme props with no joy but this has steadly got worse and it can only be the output bearing which today has started to make noise like somebody is ironing a cat. This means the front of the T/F box has to come off I will let you know how it goes
