Thanks Crashmaster. Just wondering about the transfer case also. My dealership searched my vin and it recommends hypoid 90 for the transfer case. I haven't put the car on the hoist yet so I haven't had a good look.
yea i just had to do A3 maintenance minder had no idea about the transfer fluid. where does it go and what do u use.
sorry i have v6 awd about 55k miles. did the rear dif fluid change twice already since 10k. sounding like i need to do it again since im hearing that grind while parking/reversing. just had A3 done but i missed the transfer fluid.
I bought a CT with 40k miles on it. Service history showed trans, front transfer case were changed at 30k miles, 3 years ago. Not the rear differential. I experienced a grumbling when in revers and hard right wheel, only when cold. I had the fluid changed and all is good. So, I'd recommend changing the differential fluid with the transmission and transfer case. That is my plan.
