Rear-end noise on 2009 4x4 Sport

I'm hearing an unfamiliar sound and was wondering if someone can help me pinpoint the problem. I have a 2009 4x4 Sport.

When my rear tires or on an uneven surface (right rear higher than left rear especially) and I make a fairly quick turn, I get a beep followed by a "clicking" in the rear end. The best way for me to describe the sound is that it sounds like a slipping gear. Now, I am assuming there is something wrong with the limited slip. I am not mechanically familiar enough with differentials to pinpoint exactly what the sound is but I know it is abnormal. It is only when the limited slip activates that I hear this noise. The truck drives normally on the road even when accelerating hard.

Can someone explain how this limited slip works and what exactly I am hearing?

 

the 09 limited slip isn't a mechanical device anymore... 05-08 had mechanical LSDs in the Sports.

 

So, how does it work then? Brakes? Any ideas on the noise?

 

I don't know this by first hand experience in a '09 Taco but I would be willing to bet the 'beep' is your truck letting you know the traction control/stability control is kicking in. The 'clicking' could probably be attributed to the pulsing of your brakes to correct the issue (auto-LSD). Like Delmarva said, the new LSD is fully electronic and not mechanical.

It works by applying the brakes to whatever wheel loosing tracking, thus redirecting power to the wheel with more traction.

 

No idea on how it works really -- I'm assuming the ECU senses wheel slippage and brakes the slipping wheel... much like VSC me thinks...

 

That makes sense. If anyone with an '09 has experienced this, I would appreciate your feedback. It sure is an odd sound for a component that is working properly.

 

I would say if an '09 take it to the dealership...lol

 

Oh, I have an appointment at 8am tomorrow. I just like to know what I'm talking about when I deal with those wahoos.

 

LMAOOOOOOOO he said wahoo's!!!!

 

I'm a big fisherman

 

Ok, someone with an '09, that's great. So you've experienced this? A clicking/slipping sound?

 

That's great, thanks for the input. A little disappointing though, sometimes I like to be unstable and out of control.
