Re: diff run in period
This other bloke didn't say it was so much of a whine,it was a slight noise like a hum coming from the diff at highway speed which totally went away after giving the car a thrashing.
I know of someone who has a VL turbo who uses it for circuit racing and he has changed the ratio 15 times since he has owned the car,he said it has always had a metal deposit in the oil whether he or a pro has fitted the diff together,I don't think he lapped the gears in when doing it by himself but I would imagine a pro would.
I couldn't imagine that everything is going to be perfect so to speak,that's why with a new car they tell you not to do any heavy towing so you can run the gearbox engine & diff in,same goes for fitting new gears I am told.
I would imagine with new gears you'd need to run it in because it is the final machining procedure like running in a new motor.
