Well to be honest, most other diff jobs get wiped down after but not entirely cleaned with brake cleaner. This would be the first time between me and my friends (all with subarus) that an ENTIRE diffy would be wiped down instead of just the area where the drain occurred. Granted, they didn't have theirs done at the stealership. Even if one just wiped up the dribbles, there would still be a different color on the diffy in that area form the gear oil considering that the diff was probably filthy in general from at least 4 years or road grime.
Understood on the lack of marks but the rear diffy was never touched. First fluid change. The star bolt is heavily rusted, even with a perfect tool, there would be some form or marks from going in and out of that star pattern. A tool would naturally remove some of the rust as it was inserted.
In live in NY and stealerships are known to rip people off and not do services they say they did. Especially fluid changes that are not oil changes.
I might totally be off base but from personal experience, I know this type of thing does happen.
Well, I'll know more tomorrow as once it's on the lift, we can look more closely before considering breaking open to the top fill bolt to see if the fluid is fresh. I would rather not have to do that to be honest.
If the job was indeed done, it would be the cleanest and neatest job I have seen to date.
oh paperwork says 4 quarts 80w90. Does this seem correct? Rear is 75w90, front 80w90, no?
How dirty would the rear diffy fluid be after 58K so I have some clue when we check if it has been replaced or not. I assume it would be somewhat brown no and not very clear?
Just was curious what people thought.
