Does my Tacoma have a friction plate style LSD Diff?

I know for a fact I have a limited slip differential but I feel like its almost getting weaker.
I read some wear that there is a true mechanical limited slip locking and there was a friction plate style LSD? is this true or am i just crazy because i really hope my rear diff isn't wearing out.

 

You have an lsd with friction plate style. Later year tacos have open diffs with electronically brake controlled simulated lsd's.

 

When was the last time the diff fluid was changed?

 

i believe the cut off for the true LSD is 2008, meaning 2009 and newer uses the abs to simulate a lsd

 

There is no auto/locking diff in the Tacoma. You have a mechanical LSD.
I’d change the fluid with CONVENTIONAL gear oil and add the LSD friction modifier.

Or, use Synthetic and risk having diff chatter.

 

there are at least a dozen different type limited rear differentials

why do U think Urz has issues ??
