Yeah mate, I slapped some grease on them before assembly, then put a grease gun on them once they were in, you might have to jack the car up so the wheel droops and the nipples rotate out and you can get to them.
They aren't strictly legal because they don't maintain factory specifications and tolerances for the vehicle. (cv angles, wheel clearances bump stop clearance, etc)
Good call on jacking it up haha, I'll give it a go when I get it back tomorrow. My other option was taking to it with a die grinder...
Thanks guys.
Also, after having a good look at the cross members that hold the front diff in, I'm thinking of modifying them and dropping the diff about an inch and a half. I've got some spacers made to go between the UCA's and balljoints. I know this is a bit of effort for an extra inch or 2 of lift, but I'm all about DIY at the moment.
