My gearbox is on its last legs still from last year and its crunching in 1st 2nd 3rd and 4th and also if i hammer it for some reason the box tightens up and 1st and 2nd are very difficult to disengage. I dont care about the box, but what i do care about is the Quaiffe LSD that is inside it. I have had the box out but the CV cups are what is causing the problem, one side came out no problem, but the other is totally refusing to come out. Now normally these should be a piece of piss to get off, especially with the box on the bench, but it just refuses to pop out. I have tried baring it off, wedging it off, whacking it with a hammer, beating it with a hammer, kicking the holy shit out of it and also I have tried a metal rod from the other side of the diff (where the hole is) and try and smash it out from the other side, Nothing works, i have even put the CUP in a 5ton press to try and get it out and still it remains firmly stuck in place. Its completely doing my head in, i have another box ready to go but its useless without me getting my diff out, I paid over £700 for that fucking thing!!!! Where is grant when i need him!!! Any suggestions, I am willing to completely destroy the box, just as long as i get my precious!!!!
