03 Tundra rear differential

The rear limited slip diff on my 03 Tundra is noisy, and rather than rebuild, I would replace it if I can find one. Are they interchangeable with any 4 runners or Tacoma's?

 

Have you done a drain and fill with proper fluid and proper LSD additives? That will usually quite the beast down, pardon my gramma

And this makes me wonder if i can swap my ‘02s 7.5” front diff for an 8” front diff from an ‘05-‘07…

 

Thank You . That is very helpful

 

Yes I did the oil change first but it is clearly worn out.

 

How many miles are on it? I'll be getting my diff fluid changed soon (2006, 85K miles) because I don't know when/if the last change was.

 

My truck has about 300k kilometers (I am in Canada) But that may not mean much because I pull numerous trailers with it and also use it off road hunting and fishing. It does not have an easy life, but has been the best truck I have had in the last 40 years.
