I´m doing a rear end overhaul. Had a bad clonking noise which came from the rear diff, had the OBX diff overhauled and also tightened up the backlash a bit.
Second part up was the really bad vibration that showed up at speeds above 100 mph. Used a indicator dial at the adaptor plate for the 280 ZX Turbo drive axle, and it showed a difference of 1 mm. It was even possible to see the wobble with your own eyes. Removed the strut and using the indicator dial on the stub itself it wobbled a 1/10 of a millimeter on the left side, the right side was a lot better but not perfect.
Is this something that is common? Will it happen again using the stock stub axles when trying out the surface grip with the 512 whp??
