Okay, just to confirm, the t/case and both diffs take the same fluid...Correct? I read in another thread it is recommended put 85w/140 for all three. Does that sound right? Also, how many quarts should I buy to change all three?

what do you guys thinks about using Lucas high performance heavy duty gear oil, SAE 85w-140 for all three? I can buy it at Auto Zone for $7.99 per qt.

Finally, is it okay to jack up the rear of my 2000 discovery II by going under the rear differential/pumpkin?

thanks!

 

yes , yes and yes... If you live in a hot climate like me get the heaviest.. Dont need to jack up to do the fluids...

Have fun.. Chris

 

yes, 7 quarts, from factory it came with synthetic 75W/90; Use 85W/140 for HD (towing, extreme off-roading, etc.)

I like Lucas products, is it synthetic?

Yes, though I would use jack stands under the axles before I crawled underneath.

 

Make sure you remove the fill plugs before draining the diffs/t-case.

 

Mwidth--It is not synthetic. On some other threads I learned not to used synthetics for the t-case and the diffs. you agree?

 

Reasoning?

 

I'm not sure...Maybe the recommendation was not to use synthetic for the tranny?

 

mwindth, I don't really tow that lot nor do I do heavy 4wding. Should I then use the synthetic 75w/90? If so, what brand to you normally use? If it matters, this is my everyday car. I have 141,000 miles.

 

Lucas sae 75w-140 synthetic gear oil???

 

Factory manual states for Tcase and Diffs to use Full Syn 75W/90
