I have a nagging leak coming from behind the front harmonic balancer. This truck has 380k miles and I'm worried about the LPOP not sure when PO replaced if ever.

What could I expect a reputable shop to charge for replacing LPOP and all related seals?

 

Book time is 2.7-3.0 hours and the part, from Ford, is around $100 (not including the shop's mark-up). It will come with the balancer hub seal and square cut o-ring for the pump-to-front-cover mating surface.

The variable is the shop's labor rate. It varies by region but estimate between $80 and $150 per hour.

 

Or around $120 for a melling m208 and maybe 2 hrs of your time. It's a fairly simple job.

 

In this post I attached some details about the LPOP from the Ford service manual if you feel you want to take a look.
