: Spring over drive shaft Question, pinion angle FJ45Mike 04-08-2002, 05:22 PM So the rear drive shaft on my 45 is about 5 feet long. Should I keep the same pinion angle when I go SOA or point it at the t case and buy a cv shaft. I would rather not buy a CV shaft if I do not need to. What do ya think? dog walker 04-08-2002, 05:28 PM add about 3 degrees of pinion angle and haul ass!!! Jeff FJ45Mike 04-08-2002, 07:51 PM OK stupid question time. Does that mean that the pinion should be rotated up 3 degreed beyond the angle of the output? dog walker 04-08-2002, 08:57 PM That means that when you weld your pads on top of the housing to add 3 more degrees that what you had. (stock) Jeff Land Crusher 04-09-2002, 05:27 PM the pinion angle should be the same angle as your trany is at ideally 0 but some peopple will corectly argue that you are going to get axel wrap so you could compensate for that. but if you are going to use this rig off road you will be adding a traction bar so stay at o. this advise is for the rear only front is more complicated and you only asked about the rear so. 2car 04-10-2002, 01:50 AM Axle wrap in the rear will make your pinnion rotate upwards. Rotating the diff makes it worse. IMHO leave it as is. Pinion shaft axis and transfer output shaft axis should be parallel for minimum vibration. Ben | |
