Is there any merit to changing your differental fluid immediately upon purchase?

I changed mine at 170,000. It looked fine. That was 50,000 miles ago.

 

WTF? Why you quoting me?
I do all my own maintenance.
Maybe you ain't picking up what I was laying down.

 

Front or rear?

I think you just triggered 90% of TW members.

 

Lol. I was merely jumping on the 2 year free service mention to provide some insight for the OP. Wasn’t implying you didn’t do your own maintenance and didn’t even give it a thought if you did or not. Wowser.

 

Now you know better. Bye.

 

I read comments and post and do not look or care who posts them. Guess now I’ll be looking for yours to jump on, lol. Razorbacks are spooked easily- who knew?

 

Adding an additional magnet would be more beneficial than changing the fluid.

Fluid does "break down" with time and temperature, but that is not of great concern in the diff. Metallics are a concern, and magnets get them out of circulation.

Finding crap on the plug should be a relief, not a cause for alarm. Unless the crap is filled with large pieces that can not be accounted for.

 

Changed my rear diff at 10 and 30k, front, manual and Tx at 30. No cause for concern for any of it
