Re: 2000 Lexus LS400 (Rear differential fluid?)
Hi guys,
We have a 2000 LS400. (~ 305k KM / 189.5k miles)
The other day, when we were getting the brakes serviced, our independent mechanic that services our rear brakes every year (Mobile mechanic), noticed and showed us the rear making quite the griding/metalic noise, when he turned the wheels around.
His opinion was that the rear differential is shot and likely not even worth fixing, given the likely cost and age of the car.
He figured the car might have another 12-18 months of driveability, before not being able to drive it.
Question: Is it worth at this point, even changing the rear differential fluid?
I bet it's never been done the ~ 22 years....
thanks,
Mike

I don't know if you're mechanically inclined at all but this is an easy job. http://www.lexls.com/tutorials/suspe...C%20or%20SAE90

I'd say "yes it's worth it to change it." Maybe $40 for the fluid and whatever $$ your mobile mechanic charges for the hour labor is worth it even if it does only last you another 12-18 months. Maybe the fluid has leaked and is low. Or, after 22 years it's just bad fluid. Either way, I'd do it.

Make sure to inspect the old fluid if the diff really is grinding you'll see metal flakes.

yeah it wouldnt hurt to swap the fluid (here are the few cases you do NOT have to use OEM fluids).
i also would get a second opinion. even if neglected the diff is a closed system that doesn't see big heat swings (unlike the engine), unless you had an unknown leak and the fluid level dropped significantly.
sound could also be the pads and shoes (yes the car has drum brakes inside the rear rotor hats for the e-brake) dragging making noise!

I have nothing to add other than to say:
Remember to change your diff fluid folks! Commonly forgotten about item. Owners manual says 4 years, 48k miles (it's part of the major service I think).

I'm actually thinking now about changing mine seeing how it's 29 years and 85K miles. And I'm doing the other work on my new (used) car. (When I get some ambition to work on it)
It aint much $$ for the fluid and would save alot in the long run.

Are you sure the noise was coming from the differential and not from the brakes dragging on the rotors?

But I'll still say, for the price, you should still change the dif fluid.
