3 degrees? so did it go like this?FINALLY took the time to properly set my rear pinion angle. When I first swapped to the T56 I was working off of jack stands and had no idea just how far off I was. It had a slight driveline vibration when you’d get up around 75 MPH. Now that I have lifts again I finally cleared out enough other projects so that I could spend some time with the El Camino. I’m embarrassed to admit that I had the pinion angle off by almost 3°!
Now it’s properly set and I took a nice cruise on the freeway. I might or might not have cruised along at 125 MPH for a bit. ZERO vibration now. I can’t believe it has taken me so long to get to this issue.
