bungy 2 Posted December 29, 2010 Report Share Posted December 29, 2010 Haldex is 20k and 40k for oil and oil and filter. I would of thought synchro would be treated just like any other differential. Any doubt and I'd change it. IMO it can't do any harm and always remove the filler plug before the drain. Link to post Share on other sites
