When should I change my differentials and transfer case oil?
I bought toyota sequoia 2008 4WD 5.7L in 2013. The odometer reading is
now 97000 miles. Truck is in Africa and I wanted to have the transfer case,
rear and front differential gear oil changed. However, I have combed through
the Toyota maintenance scheduled booklet but it does not state how many
miles or years old the truck has to clock before change. Went to Toyota
owners site but maintenance records do not show these fluids have been
changed. The truck runs okay but just to know if the change is necessary
TYPE OF OIL
My second problem is that Toyota specifies LT 75W-85 GL-5 for the transfer
and differentials but I am not getting this. Got it only from amazon and it sells
almost very high. I have read how some have used Royal purple 75W-90 and
Mobil 1 LS 75W-90 but I do not know if I need additives to be used with these
oils. Do you have suggestions of oil that can be used?
Waiting for your advice
I would replace the fluids now. I can't comment on brand or type, but definitely go full synthetic.
If you have a rear LSD (Limited Slip Differential) then you also need to buy a single tube of limited slip differential additive.
