TRD sport no TRC or A Trac type thing

Mechanical LSD is better for off-road. Yours uses clutches that may be pretty worn out at this point.

 

I agree with this statement.
It’s not a locker, but better than an open diff.

A trick I was told here to “simulate” a locker on a LSD, is to engage the parking break about 3-4 clicks.
Works well as it sends some torque to the other wheel.

And thanks for reminding me I gotta change the clutches. Haha

 

How could I check that?
It has around 119k miles how long do they last in Tacoma?
