So I noticed today I have a whine from 55-65mph. I am so depressed. I have broken(exploded) a few rear ends in my time, and cant afford to fix anything just yet.
I cant tell if its a new sound, seeing i have had the car for 3 weeks. BUT i did just get new tires where they grip enough that they bearly chirp when i floor it from a dead stop. so question is this...
what rear end do we have ?? anyone broken one before or know anything about breaking them??
I look foward to hearing your thoughts.

I'm pretty sure we use a standard for 8.8.. The whine could very possibly be road noise from your new tires.. What brand/model are they? Also does your rear make a clunking noise when you put it in drive from reverse? On the up side, breaking your diff would be an excellent excuse to upgrade to an LSD.. Eric

its the distinct sound of the mid range whine from the rear. i know it well. i have had quiet rears that i made loud prior to breaking. how many bolts is the 8.8? is that a 12 bolt? it shoudl be able to handle the power if so. I had to upgrade my TransAms 10bolt to a moser 12bolt to hande the power i had.
anyone break our rear ends???

interesting..
Wonder why the Diff would whine, I thought a whine is from the ring gear and pinion gears angle set up??
Thanks for the help guys.

Here is the TSB on this:
I'm getting the same whine on my 2005 S-Type at about 60 mph.

Thanks Mike. Keep us posted on this issue. I haven't noticed the whine but my wife drives this car 85% of the time, at least up until yesterday afternoon. See my post last night on our car going into "limp mode" while she was leaving work yesterday. Her trust in the S-Type is now shot and I hope that our Jaguar techs can gain it back, otherwise I'm stuck with a vehicle that she won't drive and I don't need....

I've got an 03 STR that makes the whine once in a while too. Usually around 45-65mph. It does it when the car is maintaining the same speed. Never makes the noise during deceleration or acceleration. I figured it was just one of those quirks that Jaguars have. It could also be the tires....mine are getting low on tread and I've noticed a lot more road noise and a lower pitched "hum" at certain speeds that could only be attributed to the tires.
I had an Infinity J30 RWD that did the same thing the entire time I owned it. I put 172K miles on that thing and never had a problem with the rear end. Actually, i never had a problem with anything on that car.... I wish I could say the same for my STR!! Jesus.
I also had a Mustang Cobra that did the exact same thing and nothing went wrong with that rear end either...and I put 155K miles on that car.
Anyway...unless the noise bugs you so much that you can't take it anymore...I wouldn't worry about it. Just make sure your fluid is good and you don't have any clunking sounds coming from the rear end.
Although, if your warranty covers a new rear end...I'd say go for it. As for me though...it's not loud enough or often enough to really care. And the car was just in the dealer for routine stuff and passed inspections with flying colors...so yeah...

Hi Scottie,
That's pretty much what mind does also. It has the whine at about 45 mph and then again around 60 or so and only at a steady speed. Like yours, if you put a load on it or coast, the whine stops. Also, it goes away above around 65 or so. So far, no clunks or other nasty noises.

I rebuilt the one in my family's 2000 s-type. It whined slightly and only got worse there after. About a month later, I got sick of it and roasted the tires until it blew up. The parts were pretty hard to find, everyone wanted to sell a complete unit, which I did not want. Although, for a complete unit, the price wasn't too bad.
