Thought I post a quick possible issue for other to look for.... that do do the 3&1 lift like I did check your emergency brake line that goes over your rear leaf springs. They look like they rubbed a little when I checked my before my road trip so I took the one bracket off and straitened it out pretty good (hammer and hard surface) and put it back in place so no more rubbing now on either side.
The silver bracket is what you need to straiten to help the rear hand brake cable from rubbing on the rear leaf spring and possible long term issues.
Oh thought I mention this is a quick 5-10 mins fix per side and only need a 10mm socket or wrench and hammer.
