Rear diff

For those of you who’ve drained and replaced the differential fluid, give me a few pointers, other than a new crush washer, and lube, anything else I should be aware of? I’ve got access to a lift and want to get this task completed before winter.
Thanks in advance.

 

Crack open the fill plug first.
Do you have LSD? If so send some this way

 

Got LSD?

 

2005, you're in the same boat as me and Frenchy although we don't know if you're LSD or not, I'll still put in my 2¢

• Always crack the fill plug before the drain plug (although you can fill thru the breather in an emergency)
• Update your rear diff breather valve (90930-03031)
• Lucas 80w90 if you're LSD, and also fine if you're not, it's what ECGS recommends for everything
• Fill plug gasket (
  $14 12157-10010 Toyota Oil Drain Plug Crushable Steel Gaskets Set of 10 OEM 12157-10010
  12157-10010)
• Drain plug gasket (12157-10010)
• All three part numbers may work with other years but definitely are right for 05-06

 

This is the way

 

But…….. how would you check the fluid level if filled thru the breather…… worst case scenario.

I had a buddy that loved to live daily life; worst case scenario…….. I always liked hearing his worst case situations

 

You'd need to measure reaaaaaaally good

I may be the reason worst case scenarios exist. Always seems to happen to me.

 

It’s never bad to have a worst case scenario plan…….
But my buddies were always comical, like bro take a chill pill!
I think of him planning trips and laugh, but secretly plan for some weird shit hahahah

 

Silly straw and some siphon action.

Not thick enough? Use a frappe straw.

 

Frappuccino………

 

Just throwing this out there because I'm going from memory, but I think there's an "upgrade" to switch out the drain/fill plug for the Lexus equivalent. The lexus plug has a normal hex head to replace the Toyota allen key head that has a tendency to strip out. One of those "while you have it apart" items...
