Hi built a street rod and need to know if the center section of the rear end and the transmission are not in line perfect will it cause some damage.There is a slight angle.I know about the pinion angle .Thanks

HEY STREET: I was just reading an " what's your problem" article in Car Craft magazine. It is about a guy having a vibration problem with drive shaft. Article says" To keep operating angles at less than 4 degrees, keep in mind that drive shaft RPM is higher than engine RPM" GOOD LUCK.....DAVE

Ford Motor Company has used offset rears for decades and never had a problem, 9" rears are all offset

Bob, you're correct about the offset, however, the pinion is still aligned with the transmission tail shaft laterally. As far as pinion angle, Currie recommends 1 - 2 degrees down angle at ride height, and I believe that's close to the OEM spec.

Some time ago I inquired here if Ford drivetrains are offset in the chassis and got laughed all the way to Toon Town! I'm still convinced some manufacturers do provide a small amount of offset to the passenger side, heck, probably for the heal-n-toe foot brake racers with big feet!
