Rear Diffrential flush??? 2GS400

Hello family!!!!

I have a question when is the rear diff fluid needs to be flushed and replaced? And does anyone know the best liquid to put in?? Would this be expensive from a mechanic?

you can honestly do yourself and save some money.. I was skeptical at first but over the years have done many maintenance items on the GS and have saved money in the long run... My car hasn't been to a dealer in 10 years..

75w90 rear diff fluid is what i used...

Tools Needed:
- (2) quarts of fluid, but you'll probably end up using 1.5 quarts

-Hex/star key. You'll need a somewhat big one so make sure yours fit before you start. I had to run out to my local autopart store to buy the key.

- Any type of pump where you can draw fluid and then inject the fluid. A siphon pump will not work (I tried, very messy result). Turkey Baster works perfectly fine!

- gloves

Basic Steps:
- Jack up the car
- Unbolt the lower bolt, which the differential fluid will drain down from
- Tighten the bolt back up
- Unbolt the upper bolt, which the differential fluid may be filled in.
- Take your pump and fill it up with differential fluid. Pump the fluid into the upper bolt.
- You'll know that you've put enough once the fluid starts to leak out of the upper bolt, and when it does, tighten the upper bolt.
- Lower the car
- Wash your hands
- Take a test drive
- Report back here

Warning: Gloves will come in handy. Differential fluid is probably the worse smelling fluid that goes into our car. Take a sniff and you'll know why .Having one of those orange hand cleaner will come in handy.

this is what i followed...

You should always unbolt the fill plug 1st.because if its stuck and you can't unbolt after you already drain it out then your ****ed

75k / 7 years Differential Change

I used to do it every 30k as the dealer recommended, but as discussed on this site, the manual says only needed if under stressful conditions like towing. So I quite doing it. The last time was with the timing belt change. Just had the belt done and was told it needed it on my inspection report. I should have asked if they had actually inspected the oil or just put it down as a matter of course.

Decide to do it myself and found this thread. Then decided that for $50 dollars more than the lube I would pay someone to do it for me at the local JLube ( I know should have just let the other guy do it and saved a trip as this only saved me 10 dollars. This location has a really good tech who does this stuff. When I called to inquire he knew that Lexus requires a "special synthetic" that they keep in stock and said it would take him only 10 minutes. I watched the lube come out and it looked to be in great shape after 75K miles and about 7 years. The tech told me it was in good shape with only a little green on top, meaning that some of the lube had oxidized but not enough to be of any concern. I will say the car is driven gently at this point and this is one service I am not going to worry about.
