[W126 Coupe] what's that engine part?

[Jonathan Hodgman]

Hello Lance,
How many miles are on your car?  Has the timing chain and tensioner
been replaced?  If you are over 100K I would go ahead and have it
done.  If it has been done, a new seal ought to get you underway. 
Best bet, get one from your local Stealer.

Rears are easy as Pie.. You don't want to touch those rear bearing if
you don't have to!

Were you doing fronts I would say replace the bearings if you didn't
know when they were done last.

Jonathan
