Surely there must be some way to get them to cope
I've spent more on the axle on my car than any other bit of it over the years and it now has decent halfshafts (glued to bearings, and no bearing movement issues since) a Quaife ATB and Jigsaw CW&P in it. Axle is overfilled by jacking up the rear.
It was fine when I was just sprinting it, and absolutely silent on the road for 2 years.
First trackday I do (Brands yesterday - and very slippery, so not even flat out in the bendy bits) and the axle starts complaining after 5 laps or so. By the time I leave the circuit it sounds like a straight cut gearbox. It also did this the last time I was at Brands which is why I went down the Jigsaw route, but I can't afford to do this every trackday.
I'm assuming its an oil surge or oil temp issue or both. I'm just fed up with it now, though, as being able to go for it on the track is a big part of owning the car. The rest of the car is great so I don't want to think about selling it.
So... what can be done that will actually work, and stay working?
