gadget Posted June 21, 2014 Share Posted June 21, 2014 Spent another day on my Defender. Rebuilt turbo on and fitted the refurbed props. It actually moved under its own steam for the first time since the gearbox swap When trying to grease the props the front UJs and slide greased up fine. Rear slide no problem. Both rear UJs refuse to take any grease. Took out the nipples and tried with the long ones i use on my Discovery but still no happiness. The effort required to move the lever on the grease gun is significantly more than when grease flows. UJs are GKN so i'd not expect them to be duff but you never know.

Disco-Ron Posted June 21, 2014 Share Posted June 21, 2014 Try warming it up a bit, the grease in them might just be really stiff, don't heat it to the point of damaging the seals, just nice and warm.... Quote Link to comment Share on other sites More sharing options...
Rangy35 Posted June 22, 2014 Share Posted June 22, 2014 Have you fitted the UJ's yourself? If so I usually after assembly "relief the pressure" on the caps buy reverse tapping the X to make sure the caps are seated on the c-clips, this makes the joint nice and free and greasing is a breeze. You probably know this trick already. Quote Link to comment Share on other sites More sharing options...
gadget Posted June 22, 2014 Author Share Posted June 22, 2014 Yes, fitted myself. Heat doesn't seem to have made much difference. They seemed free enough when i fitted them so didn't see the need to tap the cups out. Once the floor is back in i'll take it for a run and try to grease again after that.

ajh Posted June 29, 2014 Share Posted June 29, 2014 When fitting new UJ, you need to poke something through both ways to get the factory grease out; it is usually old and hardened up and this is why frequently they don't grease evenly/at all. Even better is to warm them up to get it out of the cross entirely, don't worry about any in the caps. Quote Link to comment Share on other sites More sharing options...
gadget Posted June 29, 2014 Author Share Posted June 29, 2014 If i ever get this thing finished and back on the road i'll try and warm them again after a decent drive and see if they'll grease up. If not i'll swap the UJs again and poke them through as you suggest. Quote Link to comment Share on other sites More sharing options...

This lets the factory grease out, then just refit the nipple. Quote Link to comment Share on other sites More sharing options...
