If don't have any leaks, I wouldn't replace them proactively. Honestly, if the power steering pulley didn't hit the subframe and chip, which resulted in the belt fraying snd then wrapping around the crank and puncturing the front crank seal, I'd still have my OEM seal. This all happened due to faulty O34 engine mounts, which were supposed to be equal to if not slightly better than OEM.
I am a little shocked that your rear main seal is still original. You have an N54/55?? Correct.
I would tell you to replace your engine & trans mounts, if they are original and you are at 160,000 miles. Either go OEM or get an upgraded set. Just stay away from 034.
