p3te Posted February 9, 2008 Share Posted February 9, 2008 Hi, my car has started making a whining sound from the rear, it only makes this noise when accelerating but completely stops when i take my foot off the pedal. it sounds like it gets louder the faster i go. Any ideas what this is? diff or propshaft maybe? any help appreciated:search: the car is a uk spec auto if that helps any? Quote Link to comment Share on other sites More sharing options...

absz Posted February 9, 2008 Share Posted February 9, 2008 sounds like rear diff if the noise reduces on overrun. might be worth checking the oil level first. Quote Link to comment Share on other sites More sharing options...

absz Posted February 9, 2008 Share Posted February 9, 2008 you need to check the oil level first. its just a start off point. if its the diff then you will require a replacement one. could be a few other things, but lets start from basics;) Quote Link to comment Share on other sites More sharing options...
and1c Posted February 10, 2008 Share Posted February 10, 2008 Sounds like the Diff. As above, drain and replenish the diff oil (correct oil only as Toyota recommend) and see if the noise goes away. Not a massive job to replace the Diff. parts arent cheap though if you go for new OEM... Quote Link to comment Share on other sites More sharing options...
p3te Posted February 16, 2008 Author Share Posted February 16, 2008 right i drained the diff this morning and there was hardly none oil in, had a look was no metal fragments or anything so i refilled the diff and took it for a spin and the noise hasnt stopped? what can i do next?

MrRalphMan Posted February 16, 2008 Share Posted February 16, 2008 Looks like running without oil has knackered the Diff, so prob replacement time. Jezz on here breaks cars so might be a good point to start. Also you'll need to check for leaks in the Oil Cooler circuit/cooler to ensure you don't go through this again.

CarlT67 Posted February 16, 2008 Share Posted February 16, 2008 Maybe it is a wheel bearing, does it sound like it is coming from a particular side or in the center...? Quote Link to comment Share on other sites More sharing options...
MrRalphMan Posted February 16, 2008 Share Posted February 16, 2008 In my experience wheel bearings do not go away with load and are only affected by speed. Whoom.... whoom.... whoom.. whoom. whoomwhoomwhoomwhoom Quote Link to comment Share on other sites More sharing options...

MrRalphMan Posted February 16, 2008 Share Posted February 16, 2008 Again from experience they normally clonk or really vibrate when running.... Quote Link to comment Share on other sites More sharing options...

geofhole Posted December 31, 2009 Share Posted December 31, 2009 (edited) Hi did you sort your 'whine' prob? I get a whine at 35 mph up and really bad at 70+ mph. Tried 2 diff's, one from scrap yard and one recon, still the same! Replaced both rear wheel bearings, disc's and pads, still the same!!. Took handbrake shoes out and ran, still the same!!! Not sure if its back or front, might try front wheel bearings next although they look and sound A1 on the jack and hand turning. After that the centre prop bearing. Its road speed related as the whine does not change with engine rpm. Anyone else heard/seen this.........help please. Oh almost forgot its a 95 NA Auto Aerotop.

Chris Wilson Posted December 31, 2009 Share Posted December 31, 2009 (edited) UK spec cars have an oil cooler and pump for the rear diff. The cooler pipes corrode and the diff loses oil, then destroys itself. If they are kept full of oil, not subject drag race starts, and kept reasonably within their torque design limit, then they are pretty much 100% reliable. You can remove all the cooler and pump gubbins, in most cases the diff oil has never been hot enough to trigger the pump to run and it's seized up anyway. I'd check front hub bearings but this post reminds me of a car I had in years ago, not a Supra, that had defeated three garages trying to trace a whining noise. I was determined to sort it and after a huge input of time found it was a noise from a none standard roof aerial resonating at certain road speeds. The noise was generally considered by all who heard it, including myself, to be coming from the back of the car... Being an aerotop it couldn't be a whine from poor hard top seals could it?

geofhole Posted December 31, 2009 Share Posted December 31, 2009 Hi Chis thanks for your comments. I will run the Supra tomorrow with the roof out but I'm pretty sure I tried this in Aug when we had a day of sunshine and the whine stayed the same. Don't have a roof aerial only the stock o/s rear electric one. Quote Link to comment Share on other sites More sharing options...
