So I have a 2014 f150 5.0 4x4 great truck other than service from the dealer around 16k miles I found a small leak in the front diff where it connects to the passenger side drive shaft soo I take it in and get it fixed under warranty supposedly got a couple new seals and bearings and 3 quarts of 75w90...... well flash forward 10k miles and in the spirit of preventive maintenance I pulled my diff plugs to check the levels and magnets well the rear was fine but when I get to the front I get this
Looks kinda wrong to me not including its over full so I call up ford and ask if maybe they added something in there I didn't know about and told them what I found they have me bring it in and look at it cuz they are skeptical as well.... well their mechanic comes back and tells me it's perfectly normal when different fluids are mixed well at this point I start asking questions like
Why did you have a need to mix fluids if you used 3 quarts like it said on my warranty receipt and why wasn't I made aware that you aren't doing your job and how did you replace any bearings if you didn't ever pulled the front cover... ect so after I get done getting [censored] answers he tells me it will be perfectly fine leaving the milky green fluid in there I politely tell them to suck it so on the way home I picked up all the supplies to change the fluid myself when I pull the cover puss color fluid drains out and there are globs of what looks like lithium grease in the bottom anyone else believe their story or am I crazy? Seems like [censored] to me well anyways 100$ later both diff are full with grape juice now and I definitely feel alot better than what they had done
