What is the OEM Transmission tailshaft angle and pinion angle with the PPF installed? As in "-3* down - transmission, and +3* up, pinion

 

I don't know if it's really documented anywhere in particular. The PPF holds the 2 in direct relation to each other so they don't independently move, they are a fixed relationship.

That said I don't think there's any real load or angle on the stock U-joints. Partially why the OEM driveshafts pretty much never fail.

 

the driveshaft is one of the 3 parts i've never seen fail on an FD, even on teh inernets, the hood rod clip is really durable too

 

Good points here. Usually many cars will have a 1 to 3* angle down on trans with matching opposite angle on driveshaft, as this supposedly lubricates the driveshaft u-joints. From what I've been reading having no angle will wear out the u-joints. But idk if this is a myth or what. I'm trying to figure out what to set mine too, it appears the transmission angle is around -3* without ppf connected. So I'm assuming I need to set pinion to +3 and this would most likely be the oem trans/pinion

 

Wears groves in them in one spot vs causing even wear across the entire surface. No angle would, in theory, cause it to wear out far faster. I would expect there is some angle, even if its not much. Should be easy enough to find if someone has a stock car

 

do some googling, the U joints are really weird, and it turns out that they generate a wave and if you have the same angle on both ends it cancels out, and everyone is happy.

actually i think there was a good you tube on it.

the bit that applies to the steering is that the u joints need to be 90 degrees off from each other

 

The fsm has a specific procedure for aligning the power plant frame, in relation to one of the underbody cross brace and tightening order of bolts

this probabaly produces the correct angles
