I bought a 2000 Cherokee Sport XJ recently. the Jeep is all stock. 98,700 miles. solid vehicle. The Driver Door sounds like its not closed when driving down the highway. the weather stripping isn't cracked or missing. its identical to the passenger side door. has anyone come across this? maybe all 2000 XJ doors are like this? im thinking of putting additional weather stripping in between the door and body. its just annoying driving down the highway. the door doesn't leak water. any input would help. thanks.

 

Is the fender liner in the wheel well? You'd be surprised how much wind it deflects.

 

The weather strips can become compressed over time and not fully seal. One remedy for that is to tuck rope or cord into weatherstips to expand them.
Also, if there was a lockout situation in the past, the method of entry is often prying top of door outward, adding shims to keep it pried open so that wire can snake into cab to unlock. If too much pressure was applied, the door could become deformed just enough to cause an issue.

 

seems logical. I have no idea if it was ever pryed on. the door seems flush with the body when closed. the weatherstripping looks in good shape bit tje ropen iDea might work. I thought about adding some kind of additional insulation in the door jam somehow, but no idea what to use for that.

 

Here is what is inside the fender behind the inner fender in my '00 just in front of the front doors. The smaller part is spray adhesived, is that a word?, to the bigger piece. They separated on me and fell out when I was in there doing some housekeeping. See the first 2 shots. Somebody here suggested a pool noodle. Of course I could not use a orange one from the dollar store and paid $9 for that black one. Cut to the proper length and then cut the diameter in half. Shoved it in there. Guess it is doing what it is supposed to do.

 

I saw on YouTube channel bleepinjeep that he used half inch rope to shove in behind the weather stripping. His rationalization was that over time the weather stripping breaks down and doesn't hold its shape when the door is closed. I got some 3/8 inch black rope from Lowe's and shoved that in behind the weather stripping as good as I could. I drove home and the cabin sounded airtight. no wind noise coming from around the door jamb anymore. $4 in rope seemed to do the trick.

 

Success! Glad you figured it out and was an easy fix
