Thanks for the reply......Son has the tiguan, rear diff is whining
Automotive tire Hood Water Rim Bumper
Food Ingredient Recipe Gas Cuisine

over 70mph so needs a rebuild? we have local transmission workshop who can change seals and bearings...and as its a used car with previous owners, some ape has removed and replaced the filter with a road drill !!!!
So i was thinking of getting another complete unit and getting that refurbished, rather than taking the car of the road for a long time while it gets done.
Pump is fine, but has a slight leak from the haldex filter cover, thanks to the "ape" as they seem to have destroyed the entry to the haldex filter with a "screwdriver/chisel" to get it out.
So not sure how to play it

So i temporarily fixed the leak from the haldex filter cover...got some Viton rubber gasket sheets. .5mm, i put the cover on the sheet, traced the shape out...so used that under the cover...no leak....
Then flushed out the diff oil, haldex oil is clean...... added some AMEtech metal tech10, nothing to start with but after a few hundred miles, a lot more quiet...still there but manageable for now till i get a complete rebuild .
