smraijck Posted January 2, 2004 Share #1 Posted January 2, 2004 Hi,I'm thinking of purchasing a 72 240z. When I test drove it, a high pitch whinning noise came for the rear end, and I noticed a tiny oil leak coming from the passenger side axle, where the alxe meets the differential. I am used to working on toyotas..AE86. A high pitch like that usually means that the the ring and pinion gear is shot but we could drive it forever as long as the fluid level was ok. Is there any safety issues since if I purchase it, I would have to drive it approx. 100 miles to get it home. Also wouldt r200 differential from a 75-83Z bolt right in? Also what is a mustage bar?Please help I just want to make sure I know what i am getting into.ThanksSmraijck Link to comment https://www.classiczcars.com/topic/9543-high-pitch-whinning-noise/ Share on other sites More sharing options...
frank13 Posted January 2, 2004 Share #2 Posted January 2, 2004 Hey smraijck, That whinning noise coild also be a bearing going out. The swap for a latter R200 diff is almost bolt in, with the right mustach bar. From the donnor car. Do a search in the forums for it. The mustach bar is what holds the rear of the diff up into the sub assembly of the rea suspension.If you can wrench there should be no ?'s. By the Z and keep it running.:devious: Link to comment https://www.classiczcars.com/topic/9543-high-pitch-whinning-noise/#findComment-62559 Share on other sites More sharing options...
