<div dir="ltr"> well, there is the "ignore it" approach. If you have a spare diff or three, no big deal - you could drive 'til it craps out, though at that point a rebuild is probably out of the question!
<div>Back in the old days in Pittsburgh, when I got a $200 car every winter to drive through the ice, salt and potholes, there was no maintenance, as long as it started. Of course, that’s because I was preserving my sports car in the garage.<br>

<div>You can’t really “pull the cover” on a Spit/GT6 diff, but it’s easy enough to drop the whole diff and much easier to examine on the bench. <br>

can be checked by pitching the car side to side (no traffic, wide open parking lot) to change the loading and hence the level of whine.</div>

<div dir="ltr">Whining is because the gears aren't meshing properly. This will result in premature wear if you're lucky. If you are not lucky, you'll overheat the diff and / or otherwise destroy it. Sometimes the noise can be from something really

<div>Hi All.</div>
<div> I am hearing some whining going on behind me when driving my 68 GT6..</div>
