Found this dangling by a thread. 4.0 AW4 NP242 XJ. 89. It's the bottom end of a breather line. The upper part is ironically safely zip tied at the firewall. Which breather could it be? Anyone recognize it?
Thanks!

 

Driver's side firewall? Front diff.

 

I just changed my oil today and notice the diff hose worn in half by the front driveshaft universal. Would this cause that 0303 code for evap system small leak engine light to come on?

 

There are three breathers in the front--D30 strapped to drivers side firewall, transmission and transfercase on the passenger side. There is also one on the rear axle usually tied up to the floorpan.

 

no

 

OK thanks
