Jeep Wrangler Maintenance and Repair Questions 2007 and newer

steverstever Posts: 52,683
Please use this discussion for repair issues on your newer (2007+) Wranglers. Thanks!


  • Don't know if this is the right board to put this Q, but what the hey...Just bought a 2007 4-door Unlimited Sahara last weekend. I'm finding that at freeway speeds, the truck bounces up and down a lot as if the road were very bumpy -- kinda makes me car sick :( This is my first Jeep -- is this typical Wrangler behavior, or do I have a tire balance problem?

    Would appreciate any feedback.

    It's not typical for the previous model, and the suspension layout is little changed for '07. However, I believe that spring rates and shock settings have been altered to give a more car like ride. It's definitely not a typical description of a tire problem.

    A certain way to check is to see if you can drive a similar model to compare behaviours.
  • I'm definitely not experiencing a "car like ride." I suppose I should go back to the dealership and see what they have to say. Thanks for the feedback.

    Hey there,

    I ran into a guy who had the same problem..I can't remember what he called it...Jeep told him it was normal...he thinks it's a suspension problem, and is pretty nervous driving at high speeds...I'd go back to the dealer and raise hell..a car shouldn't do that anywhere, but especially on a highway...Good luck.
  • I have the 4dr and do not have this problem. It drives about as smooth as my wife's explorer.

    I have the same jeep and have no problems with "bouncing". The suspension is stiffer than most SUVs and when I hit a bump with any speed it is a little hard however it rides on smooth pavement as smooth as anything else I have ever driven. I would think you have some problem either with tires or suspension and need to have it checked out at the dealer.

    Does the 3.8L V-6 in the JK use a timing belt or a timing chain? If it is a belt, does anyone know at what mileage the belt must be changed and how much it costs to have that done?

    I am looking at 4-dr UNLIMITED Sahara

    Anyone else have a HIGH PITCHED SQUEAL between 1500 and 2000 RPM's?
  • tidestertidester Posts: 10,059
    My first guess would be that it is one of the belts. Anyone else?

    Dealership replaced tensioner pulley, serpentine belt, throw out bearing, pushrod,and slave cylinder so far.Now the dealership is waiting on DCX to come up with another possibility. Any ideas?

    Stationary, while in motion, or both?
  • mreipmreip Posts: 9
    While in motion when shifting. Revving the engine in neutral doesn't produce the noise.
  • mac24mac24 Posts: 3,910
    Just a guess, but it sounds like a bad input shaft (first motion shaft) bearing.
  • Getting a high pitch squeal out of the transmission input shaft bearing sounds odd... I have not had a Chrysler 6 speed transmission apart but most manual transmissions have roller bearings on the input shaft. If it is squealing, the pitch will rise with the RPM, but usually they just grind. My guess is a timing belt idler pulley. I believe there are 2 on the 3.8.

    I have a 2007 Jeep Sahara Unlimited. Recently I had to have the windshield replaced because of a crack from a rock.

    I went to a reputable glass place and had the windshield replaced.
    What I noticed after replacement was a high pitched noise (which sounds like a teapot coming to boil) at
    speeds between 30-45 MPH. I took the jeep back a week later
    and they replaced the windshield again.
    The results were the same only the speeds at which they occurred was 40-60 mph.
    As you know the windshield has no molding. Has anyone experienced this and found a reasonable solution?

    Just to relate to your windshield replacement situation, I had mine replaced and do not have any problems - except for what looks like a somewhat sloppy jop with lots of caulking around on the inside. Good luck.

    I have a 2007 Jeep X Unlimited with an automatic and I also have the squeal that you describe at about 1800 RPMS - roughly 2200 RPMS. The dealer mechanic said that it sounds like normal engine noise to him. I want to drive another Jeep to see if I can reproduce the noise. We shall see.
  • clewsewclewsew Posts: 7

    I went to the dealer to pick up the Jeep and asked if I could test drive another Jeep to see. It made the same squeal and it was new off the lot, mine having just over 400 miles.

    A good friend of mine also did some research and found that it may be some venturi noise through the intake. He said that there have even been some complaints from owners of the Mini-van with the 3.8L engine. After hearing that and experiencing the same noise from another Jeep I feel much better. May be a "character" trait of the new engine.

    Hope that this helps...

    Answered in your other post with the same question as follows:

    "So, is this a new Jeep with exactly the same problem as your last one?
    Just take it back to the dealer to have it fixed under warranty."
  • erickplerickpl Posts: 2,735
    That is a safety problem. Take it back now!

  • pjeep1pjeep1 Posts: 5
    Thanks for your answer
    The Jeep is at the dealer, But I had one accident with it and the Jeep are declared scrap. And part of the reason was the interlock didn`t work

  • comkromcomkrom Posts: 6
    The Shifter is defective, take it to the dealer and have them fix it.
  • comkromcomkrom Posts: 6
    there should be spray foam insulation in the windshield pillars.Maybe the windshield repair place removed some of this foam.Remove the trim around the windshield and spray foam into openings. them TAPE all open "slots' for an hour or so foam does not leak out of slots. and then re-install trim

    Hi all. I'm a proud owner of a new 2007 Wrangler Sahara, but I'm getting really frustrated with the soft top. The plastic Swing bar brackets do not stay in place on the rail, specially when I tuck in the soft top. Has anyone else had this problem? Any fixes? Also on rainy days the top leaks water into the car at the top of both doors right above the door handles, again...anyone else?
  • Hey man. I've been having the same problem with my 2007 wrangler. The soft top leaks from both sides onto the tops of the door handles when it rains. I've brought it back to the dealer 4x and they have had it for 4 weeks this past time trying to fix it. I have recently filed a complaint with the BBB and I'm also filing a lawsuit against Chrysler under the lemon law. I advise you look into doing the same. it's obviously a problem that can't be fixed... Good luck.
  • If anyone has had a problem with a 2007 Jeep Wrangler Soft Top Leak, Please post a reply. The leak typically drips to the tops of the door handles on either or both sides. It usually only happens when it rains. I have brought the Jeep back to my dealer 4x and they have not been able to fix it. I have filed a complaint with the BBB and am also filing suit under the lemon laws of NYS. Any feedback would be helpful.
