hopefully this helps

found out some info on what your pinion angle should be for you diff.

where ever the car is sitting, put a level on the front of your crank pulley, note the degrees it is at the make sure your pinion angle on the diff is the same.

simple and effective way to make sure your driveline is straight.

i would have to argue that Benno. same degree angle.....different planes. hows that car running while i got ya here ?

 

[benno440]

sorry to they recommend that angle but if drag racing etc. you can go 1-2 degrees up.

thanks for asking bud just last night i fixed the rear main seal leak, installed the new starter and my return line to the tank ,just waiting on my new run in oil and a couple of fittings for the 1 way check valve and fuel filter then hopefully she will be going for good, on a good note my custom wheels turn up tomorrow from the states, looking forward to that.

gotta agree with dog on that one.if your car was jacked up(stink bug look)your pinion would be pointing at the ground.

 

[benno440]

so where would that theory work? if ride height was at factory spec?

i am trying to determine my correct pinion angle on the charger it has a tubular k member and 4 link so it will be low, maybe this theory will work for my setup, is there a more universal way to correct the pinion angle?

 

[tpodwdog]

your universal joints are made to have things at different angles.....like the rear end vs. the engine / tranny. ...within reason of course. your car looks like it sat when stock so i wouldnt be concerned....but then again,,,,i dont race and never had to be concerned with that knida stuff. when you mash the loud pedal...2 things are going to simultaneously happen.......1. your engine is going to lift up on the drivers side, and 2, your rear end is going to twist upward. this is where the U-joints take the most abuse.

I'm no genius but what you (Benno) suggested sounds like the right method of going about. If your car is stink bugged or not the angle needs to be measured to the angle of the motor not the car. I wouldn't think the normal rules would apply for your setup as with your four link you won't see any axle windup meaning your pinion angle shouldn't change much at all depending on the four link setup. Let us know when that thing is done, I'm looking forward to seeing it as I'm building one allot like it.

as an example,the above two cars have the same eng angle,but,will require very differnt pinion angles.

I did some looking around, don't think you'll find two that agree but they all seem to agree that you want the two (trans & pinion) to be parallel or 1 degree (for 4 link & street use). The one thing you have to remember is for the two universals to spin evenly the angles need to be the same or close to it which the method you suggested would achieve. What do I know though

that 66-67 is bloody ridiculous haha
i understand what you mean though

thanks mate, very soon hopefully

that looks like something RAT-FINK would be driving

like the angle of that dart........

thats a '66 belvedere or satellite....not a Dart !
