Finally got around to pulling my vacuum and power steering pumps in order to address an oil leak. A pre-purchase inspection showed a crack in the coupler between the two pumps causing the leak. The shop suggested replacing both the pumps as well as the coupler based on the assumption that the crack could have caused mis-alignment of internal shafts leading to wear, etc. Or there could have been some mis-alignment which caused the crack.The vacuum pump, which includes the coupler, runs $460 and the PS pump is $62, not exactly chump change. My local Napa can't source just the coupler.Looking for opinions. Is there validity to the potential damage to the pumps from a cracked coupler? If so I'll just buck up and pay. I don't want to have to this again, it was kind of a PIA getting that thing out.Thanks for the input.
