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

At the Chevy dealer I work at, we have an employee with a 2006 TRD Sport with mechanical LSD. When we serviced his rear diff, we used standard 80w90 gear oil with GM limited slip additive and several years have passed with no issues.

 

Used master pro 75w90 full synthetic bought crush washers from dealer, done deal

 

I put in 3 qt in and The oil never ran down do I add more or just 3 and that's it? I'm using one of those pumps to put the oil in.

 

Same here. I just closed her up since I only bought 3 quarts. I plan on checking in a couple hundred miles.

 

I stuck my finger inside and it was close so I just added another half and started to come out. Then closed it up let it sit for a minute and topped it off will see how it works out...

 

I used a hand pump also. what a POS! Do you have a recommendation on a nice one?

 

Should be 3.12 so add 3 then 100ml more from the other bottle. On the side it goes by ml so just eye it.

 

So just went to dealership after reading bulletin that only toyotas oil should be used in my 08 lsd rear trans or damage may occur. They want $80 a quart!!!

 

Most people with your year model and LSD put dino oil and add the LSD additive

 

Damn! I thought Amsoil was high.

 

Thanks for this!

 

I guess I better get busy. I'm at 60K with a 2010 Taco. lol

 

Can I get a straight up reply.... Is this safe to use front and rear... 09 trd sport

 

Well I hope you do get a straight reply, but do you have your user manual? That's how I figured out which is best for my rear differential.

 

I was looking at that at Canadian tire wondering the same.

Decided for the most part to get Redline

$29 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90 gear oil with LSD addictive for front diff and rear LSD diff and Redline MT-90 for transfer case and manual transmission.

 

Per the manual..

 

Yes, that will work great, I used Mobil 1 75w90 on both Diffs, and Transfer Case, she runs great. It's about as clear as mud trying to figure out with oil to use, but that Royal Purple 75w90 will be perfect, the other option is you can stop a Toyota Stealership, and buy the very same oil filled at production of your truck from the parts guy, that is, if you feel so inclined.

 

Does front and rear differential and transfer case use the same oil? It's for 2006 4X4 TRD sport.

 

Believe so
Double check your manual in the SPECS section

 

+1 to all of this.
