Hilux diff placement

Still building this bloody 3link in the back of my old surf and was wondering... Is there any reason why the diff has to sit straight up and down like it was with the leaves? The only reason I can think of is to lubricate the pinion bearings. If I can lay it back abit wouldn't it take abit of stress out of the uni?

yeah its best to rotate the pinion to point towards the transfer case

and to put a little bit more oil in the diff, because as you rotate it further away from the oils normal leavel, some bearing etc mightn't get the right amount of oil and sieze up

Preferably you would do this with the diff centre removed so you can remove any swarf tha the drill creates ..

Might throw tail shaft out of balance if uni joint flanges are not aligned to counter balance at each end.

Was talking Supasurf the other night - nasty looking toy - he was telling me that unis work best when they are on a slight angle.
One other thing tha caught my eye is the fact that the rear uni is my first line of defence for the rear diff, has anyone sussed out a way to protect it?[/img][/url][/quote]

If you run a double cardan joint on the rear shaft the the diff should be angled up to point at the box.
If you run just single uni on both ends of the tailshaft the diff needs to be parralel to the box.
