Hot Rods Offset pinion

Throwing a 9.25 Durango rearend under my 59 Willys PU . This rear has an offset pinion , will this be O.k. ? It will make the driveshaft run at a compound angle.

 

It is not actually a compound angle. it is a single angle 'clocked' a bit. It is common on many, many vehicles, including the Durango from which the rear end was scavenged.

Compound U-joint angles do occur when the transmission and axle are not in line when viewed from both the top and side. The compound angles have to be calculated to obtain the true u-joint operating angle, fact....not opinion.

I've built 2 vehicles with 8.8 Ford axles (offset pinion) and they run smooth. No worries, as was said, the factories have done it millions of times.

 

Most rear ends are not "centered", so no problem. That is what the U joint it there to take care of.

Thanks for the thread and info and links - working on setting my 9 under my truck and mocking up drivetrain

 

The Dana link is awesome, thank you. If you look closer at many (if not most) vehicles from the late 60s on up there's more than just the pinion that's offset. The whole drive gig is too. GM 'F' bodies and 'X' (Nova/Apollo/Omega ?) were 3/4" to the right. Some Mopars were almost 1" to the right. You can see it at the main crossmember in subframes. The slight shove to the p***enger side gave them just a bit more real estate for steering and pedal logistics. While it can be used with a compound angle as stated above the true reasons for the move was room. Why or how do I know this? I've tubbed and done back half work on more cars than I care to recall. Early stuff, say 63 (some later, some older) remained in the center but you'll find the change from about 67 and up. Again, you'll be ok with it, but I thought it worth mentioning for those who may take a front sub or frame section from any number of late model cars and stuff em under the "good stuff". And thanks again for the link...
