Toyota Trucks: MDT Tech help Is my Limited Slip diff is failing ?

"news.comcast.giganews.com" wrote: 

Most limited slip diffs can only handle a certain difference in traction between the two wheels. If the difference is too high (like one wheel on dry pavement and one on snow/ice) there is not enough traction on the slipping wheel to get the diff to lock
up hard enough to get you moving. One thing you can try to help is to ease the parking brake on to load up the slipping wheel and "fool" the limited slip into thinking the traction is higher than it actually is. A limited slip diff s called "limited"
for a reason, its not a 100% locking differential:

While experimenting with my LSD (not the kind I did back in the 70's :-), if
the "slick" wheel spin was too fast/abrupt, the unit would not engage. If I
went lighter on the gas pedal and the slick side started spinning slowly,
things would lock-up and the other side on the pavement would get power.

Good LSD'ing to ya,

If it has tits or tires, its gonna be trouble.

This is not unusual behavior. Sometimes you need a little resistance to
get the limited slip to engage. Lightly applying the parking brake will
often do the trick. Here is a link to a Ford forum that discusses this
very problem -

Well, it can slip, it has clutches. Accel easily after letting it stop
spinning. When there is a big difference from side ot side, it can slip,
so accel easily.

Inasmuch as the Democrats are complaining on how long the war is taking,
consider this:

It took less time to take Iraq than it took Janet Reno to take the
Branch Davidian compound. That was a 51-day operation.

It took less time to find Saddam's sons in Iraq than it took Hillary
Clinton to find the Rose Law Firm billing records.

It took less time for the 3rd Infantry Division and the Marines to
destroy the Medina Republican Guard than it took Teddy Kennedy to call
the police after his Oldsmobile sunk at Chappaquiddick.

It took less time to take Iraq than it took to count the votes in
Florida! TWICE!!!!!

Damn our military is GREAT!!

Basicaly I started the activity with little throttle.
I could let it slip simpily by releasing the break.
So I was not on the throttle and I allowed slow numerous rotations of the
loose wheel.

This happened to me again today.
Steep driveway.
A narrow strip of ice was left over, (due to my wheel tracks)
As I approached the garage everything was spinning at the same speed, then
boom
one of the rear wheels hit that Ice, I spun out and never regained traction.

I had to back up and make a run for the garage and let momentum carry me in.

So if this is how it's supposed to work then why did I pay for the option.
It doesn't help me when I need it and assists me breaking loose both rear
wheels under thrust while turning in an intersection.

So why is this all bad and no good, everything I am seeing is consistent
with an open diferential open.

If I do a test where a jack one side up, and I never engage the other wheel
and pull foward, doesn't this indicate I've got a warranty claim.
I need to get this fixed before I am out of warranty.

If it is a clutch-type LSD, are you sure you have the proper LSD additives in the differential gear oil? And are you sure you have a limited slip in the first place (check the axle code in the model info tag to be sure). Have you tried the brake biasing
technique, for a rear LSD, use the parking brake, gradually apply it as you bring up the engine power slowly and see if you can load up the LSD enough to get some torque to the wheel that has traction. Its quite effective when you can master the
technique, I was able to lock up my TrueTrac LSD even with one tire in the air.

IMO, nothing you read here will relieve your snit about this. So why not
take it into the dealer, file a warranty claim, and then see what falls out?

Thank you, Paul. See you on the radio Saturday.
