Oil leak and grinding noise from front wheels when turning at low speed only

Hi

Jeep commander 3.0 crd

I've found oil leaking down from this bit of the car, just in front of the transmission.

Please can you help identify what bit this is in the pic and what that rubber grommit with a hole in it is for?

Going to change my pcv valve just incase it's pushing it out through the seals......

Also the front wheels make this grinding noise at low speed. It was clicking too but since changing the differential oil the noise has stopped but the wheels rubbing a bit when turning at low speed. Garages have no idea.

Thanks everyone!

Michael

Did they change the transfer case oil? It take a special oil or you will get "Crow Hop" on the front wheels.
2 Quarts of Mopar nv245 / nv247 / nv249 Transfer case fluid.

Many thanks. I did change the front and rear differential oil with 140w and mopar friction, but not done anything with the transfer case.

Will give that a go on the weekend. I have qdII so will add NV245. Assume it doesn't need any friction oil too?

Thanks so much for coming back so quickly.

Any ideas on the oil leak and where that might be coming from? Could the pcv fix that?

Oil leak looks similar to mine.
I thought it to be the rear crank seal but since think it may be the sump seal which also has little blobs of RTV to close some spots. Not sure if this is the same on the CRD motor though. Mine is the Hemi.
There is a dust cover between the trans and the rear of the engine. One suggestion was to remove that and run the motor to see if you have any active leak on the seal. Is it ATF or Engine oil?
