doctorjay Posted September 9, 2009 Report Share Posted September 9, 2009 I installed my JLT CAI a few weeks ago. This last week when pulling out of the garage I started noticing a few spots on the floor. Took it in to my FORD dealer and they had to replace the pinion seal. Pretty sure they didn't even pop the hood and notice the CAI. Is this a coincidence or have other people had trouble with the pinion seal after mods? thanks Link to comment Share on other sites More sharing options...
