dantd5 Posted June 10, 2009 Share Posted June 10, 2009 I am wondering if it would be advisable to whack the hell out of this UJ ? The upper end of the drivetrain towards the transfare box came easily out but the one towards the back axle is a PITA Check pics below; Last pic is the culprit and it is extremely tight and wouldn't budge!!

GBMUD Posted June 10, 2009 Share Posted June 10, 2009 I am not sure of your question Dan. You seem to have replaced a UJ, what is the problem? Is the joint too tight now it is fitted? I usually give them a good whacking all round once fitted to ensure that the UJ bearing cups are hard up against the circlips, this should ensure a free joint. If not, take it all apart and check that you used a quality joint (nothing less than Hardy Spicer, GKN, Timken or genuine) and that all the needle rollers are where they are supposed to be - i.e., not lying in the bottom of the cup! In my experience cheap UJs are a false economy and a poor fit. HTH Chris Quote Link to comment Share on other sites More sharing options...
David Sparkes Posted June 10, 2009 Share Posted June 10, 2009 I read the original post differently to Chris. Dan has successfully changed 1 UJ, (at the T Case end of the shaft). He is now trying to change the other UJ (at the differential end of the shaft). He has removed the circlips, but his 'standard' removal method, using the various sockets and vice also shown, cannot move any of the bearing cups. Should he use the hammer, also shown in the picture? My observation is that the yokes are not physically damaged, nor excessively rusty, so there is nothing in the way of the cup leaving the yoke. So it must be just tight. The maximum pressure given by the vice is limited, the thread is too coarse, so yes, it needs help. A little heat on the yoke would help. That is, not red hot, but too hot to hold in a bare hand. The hammer shown is a little too light, it requires too much muscle from the operator. More strength means less accuracy, increasing the risk of an accident. Better to use a heavier hammer. Or you use a press, which I guess you don't have, but perhaps a friend or local workshop does have. HTH Quote Link to comment Share on other sites More sharing options...
dantd5 Posted June 10, 2009 Author Share Posted June 10, 2009 For real!! So it neads a real good whacking with som sledge hammer right? Thanks Dav. You got exactly what I meant. But it does not look knakered does it? After deliberate attempts, I gave up and put it back. But will see what I can do. Thanks for the imense info. My fear was to break the prop into two..

Les Henson Posted June 10, 2009 Share Posted June 10, 2009 I wouldn't bash the cup too hard - it's possible to bend the yoke. Les. Quote Link to comment Share on other sites More sharing options...
dantd5 Posted June 10, 2009 Author Share Posted June 10, 2009 I wouldn't bash the cup too hard - it's possible to bend the yoke.Les. So Les your advice is on tender hammerings right? I tried some "gentle" batterings on the first UJ (towards the T casing) which also never gave up until I used some pressure. It gave away finally though. Hmmmmm (in a Bart Simpson manner) Is it possible the yoke can rust into the shaft? Now I am getting scared fo doing something wrong.......

jacks906 Posted June 10, 2009 Share Posted June 10, 2009 i think i read it right if you place the uj in the vise with a sutibale socket like you used for the other one aply a fair amount of pressure threw the vice then a few taps will make it pop out your more just jolting it and if it moves slightly the pressure from the vice will shoot it out dave Quote Link to comment Share on other sites More sharing options...
Les Henson Posted June 10, 2009 Share Posted June 10, 2009 It might be a good idea to cut the spider out with a disc cutter, then knock out each cup individually. Les. Quote Link to comment Share on other sites More sharing options...
NicTheOrange90 Posted June 10, 2009 Share Posted June 10, 2009 It might be a good idea to cut the spider out with a disc cutter, then knock out each cup individually.Les. I second this approach, if at first it does not budge, cut it out ! Quote Link to comment Share on other sites More sharing options...
dantd5 Posted June 11, 2009 Author Share Posted June 11, 2009 B) Thanks to all for the advice. I'll see what I can do about the disc cutter. rgds Dan Quote Link to comment Share on other sites More sharing options...
