Offset pinion and driveline angle? I nned advice.

Hey folks- I've looked in the knowledge base and found lots of info about pinion angle but I couldn't find any answers to my project question. I have a 8.8 inch explorer rearend under my Olds 3 window coupe project. The pinion is offset to the right by about 2 inches. My drive shaft will be 45 inches long, giving me about a 2.54 degree angle at the u joints. Will this be a problem? It looks like I will have about a 3 degree negative pinion angle in the up/down plane. Will this create any more or less in the way of a problem. I sure apreciate your help. Mike

There`s a article in a past issue of hot rod that I have where someone placed a 8.8 in a GM vehicle and was concerned about the offset, they said it would be fine that way, that the U- joints wouldn`t be effected by it, and that most ford vehicles with the offset rear also had the engine and transmission offset to compensate.

Why not offset the engine a inch or so??
That would lessen the angle.

That's what I did on my 32 with a 60's Bronco 4 wheel drive rear axle. I moved the engine over about 3/4 of a inch. Gained a little room around the Vega steering box also.

rear end

Hey ; Mike I remember talking about a 9 inch with ya awhile back, I see you found the rear you want! Hows the width? and you got the rear disc too? If so , what kind of master cylinder you going to use. Just curious.

Not to worry. If your vehicle's differential has the pinion offset to the side from the center of the output shaft on the transmission, as a lot of Fords were from the factory, the angles created by this offset will not cause a vibration. The pinion shaft and the output shaft are still parallel with respect to these side-to-side angles and that's the important thing.
