Rear end grumble?
 

I've got about 7000 miles on my FR-S manual car and in the last 1,000 miles or so I've had a grumble from the rearend. It seems to only be noticeable when at a stop and then taking off while turning(like exiting a parking spot). Seems to send some vibration and make a noise that sounds kind of like turning in gravel. At any speeds more than barely above idle in 1st I don't notice anything. Anybody else having anything like this? I would typically think it's the diff, which seems to be pretty aggressive, but it's recent occurrence makes me think something else.

Thanks for any ideas.

Try Beano?

Seriously, it does sound like the Torsen diff. Why would you think otherwise?

I don't know...the fact that it just recently started doing it was a red flag. I used to have a camaro ss with the torsen too. It never did this.

Mine does the same thing every day that I leave my neighborhood.

Yea..it seems to be in the same kind of situation most times. I'm not terribly worried, but I would like to hear if many more people are getting the same thing.

try fresh fluids?

It's definitely the LSD... I find that if I turn super slow (for example exiting a driveway); the noise will be heard on mine as well. Don't lose sleep over this. :)

I would still think the factory fill is considered pretty fresh at this point;)

Sounds like your rear end has been using to much LSD. :-P

That it has...about 5-10 times....DAILY!
