Ghost14 Posted May 16, 2010 Share Posted May 16, 2010 Hi, I have a 200tdi disco engine in my defender 90, it has an auto gearbox and a 1.2 transfer box (which is why i'm posting this here and not in the defender forum ok so here's what's happening. there's a mechanical whining sound coming somewhere from the the driveline It is there when there is power going to the wheels but when i take my foot off the accelerator it stops It changes linearly with vehicle speed NOT engine speed the faster i go the louder and higher pitched it gets I have removed the rear prop and driven in diff lock and it is still there so I'm guessing it's not the rear diff, and i'm pretty sure it's not the front therefore it must be something to do with either the transfer box or the auto transmission. does anyone have any ideas what this may be or how I could go about trying to find out?? could it be a bearing thing??? I've added an audio file on youtube so you can hear what i mean. you can hear at about 8 seconds where i come on and off the accelerator Quote Link to comment Share on other sites More sharing options...
Andy Posted May 17, 2010 Share Posted May 17, 2010 I assume you've done the obvious & checked the oil levels in both boxes? Quote Link to comment Share on other sites More sharing options...

monkeyb0y Posted May 17, 2010 Share Posted May 17, 2010 sounds like mine - and i think, mine maybe layshaft bearings.... everyones different though...might be worth an oil change and check the plug for severity of fillings.... then refill with correct oil and some molyslip...see if this improves things?..
