Default Leak around front driveshaft

My wife's 2010 AWD has developed a small drip coming from where the front driveshaft goes into the transaxle. Anyone had this issue? Looking for feedback on repair and approximate cost. Guessing a seal?

Your guess can be correct, but please investigate a bit and let the mechanic diagnose it, instead of telling him that the seal is leaking.

Place a cardboard underneath to collect droplets.

To confirm check that you are actually loosing fluid and the wetness is due to transmission oil. From the pictures it appears to me that the rust is forming and if I am right then the leak is water and the plug above the shaft appears wet. Something in the cabin is then dripping down.

I agree with Salim.
The water source may be because your air conditioning drain is clogged allowing water to overflow where it is not supposed to go causing the wet area and rust. Transmission fluid would not cause rust.

It's not water. It's definitely oil, kind of a honey colored oil that smells like gear or differential oil.

I think you have already diagnosed it.
Type of fluid ->
Source of leak ->
Repair.

Statistics do not apply as your case can be an outlier and it is what it is.

OEM seals through the dealer will be the costliest but the labor is going to outweigh the cost of the seal. You don't need Lexus trained mechanic to replace the seal so your options are wide open. If you want to attempt DIY let us know.

You can call shops around you to get the cost of repair ... I would insist on itemized estimate on parts and labor]. Personally I would let the shop diagnose and only insist that they use OEM part. I would not supply them the part(s). The choice is yours, but I am sharing my personal choices].

Feel free to pm me or post any specific question to be answered.

Thank you Salimshah! It does appear as though this might be a rare occurrence. I will update this thread with the outcome for future reference.
