Changing differential fluid - A step by step "HOW TO"

Thanks for the write-up guys. Just flipped 30,000 so started searching threads for maintenance items. I've read through a lot of this tread and it seems that there are mixed reviews on using synthetic. The local Advance Auto Parts has Royal Purple Dino for $20.99. Amazon has Royal Purple Synthetic for $17.79 and free shipping. The price difference isn't a big deal and don't mind paying more for the Dino oil if that's better for the truck. What would you do? 2011 Base SR5 4x4 Thx

 

being to lazy to do this myself(unheated garage in winter),i had i done and told them not to add any additive to it...but when i started to look the the receipt i notice that it said that additive was added to mine ...its a trd OR, is this a problem or issue waiting to happen?they said no harm done and that its good to have it can someone add there 2 cents on this

 

Dang really? I've got an 08 and filled with full synthetic... So far honestly somehow my gas mileage has improved. Do I need to switch it out and replace the synthetic?

 

Thanks for the quick response. Will get this done today. Although your "Reps" are full I added to it anyway. Cheers

 

I just changed the oil in the transfer case, started it up and put it into H4, then put it into L4 and the beeper went off, then back into H4 the beeping continued, then into H2 and the beeping still continued and still read in Lo. Finally after going up and down the driveway I stopped and put it into Nuetral and into H2 and it went back to normal. Anybody have any ideas?

Thanks

 

This seems like such a simple thing to do.... unless it seems like the fill plug has been welded on at the factory... Not literally, but I could not, for the life of me, get the thing loose... Tried a cheater bar too, no go... I usually don't have that much trouble with simple maintenance but this truck is making me feel less and less mechanically inclined...

 

So I contacted the local shop I use (not a dealer). I told them I couldn't get the bolt off but already had the gear oil, what would they charge to finish it up? $83.49 for labor using my oil. Suddenly, I became more mechanically inclined and got my hands on an impact wrench and got that bolt off. Turns out the previous owner must have been on top of things, the oil came out pretty clean and there was nothing on the magnet. Anyway, thanks for the write up and saving me $83.49

Should I use the same oil and additive for the first gen non-Trd?

 

LS?

 

Nobody seems to read whole threads anymore..

Why should I read, when I can ask the same question that's already been asked 100 times?

 

1000 X more like it

 

Dun. Thanks for the write up. Front, rear and transfer case all happy playing in royal purple now. Just a little late @ 41k, but nothing to speak of in either diff and the transfer case looked like new oil.

Time to roll out to the Endemion parade.
in that order for the rest of the day
