8" backlash question
Let me pose my rearend question in a different manner in the hopes of getting some feedback. I purchased a new center section, with new tracloc, and ring/pinion and dropped it in my coupe just before I started my restoration. I checked the lapping they had done and the pinion was centered on the ring, as should be. I dropped it in, broke it in, all was good. Noticed after roughly 200-300 miles I had a subtle whine, and eventually a clunk coming from the rear. The car has sat being restored for the last 2 yrs or so, no miles. Was under the car resetting driveline angle (dropped suspension) last week and turned the driveline by hand, noticed more play than the expected .0008-12 backlash. So...... I suspect the extra play has come from the bearings seating, and being broken in. I'd like to pull the center section and recheck backlash, to insure nothing is damaged. I have the dial indicators and tools to do this work, but have never worked on a rear end. Doesn't seem difficult, and don't intend to break the unit down, just double check side load followed by another lapping to check ring/pinion mesh. Have any of you done this with positive results?
