Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Lincoln Aviator has been in shop 12 times, 4 for whine in rear end. Rear end replaced twice & still whines. Last time they told me this was normal and could not be repaired. This Aviator has 17,000 miles. I tired of the whine and trips to dealer, I do not was this Aviator or a new Aviator... I demand full refund.

2003 Lincoln Aviator has a howling rear end noise that starts at around 30 M.P.H., Lincoln service advisor states that Ford is aware of the problem and it is an engineering defect that they are working on resolving. The defect is the engineering of the differential. If this was to fail completely the vehicle would loose control. We continue to call to find out when they will have resolution and are told no solution but that the engineers are working on it.

Love my '03 Lincoln Aviator except for the same annoying noise coming from the rear end as complaint number 10045568. Currently on my second rear axle assembly. Noise returned at 1200-1500 miles, and was so loud my 76 year old mother asked what the whining noise was. Lincoln needs to correct problem, and this machine will be perfect.

Our 2003 Lincoln Aviator started a rear end whine or drone within the first 1000 miles. The dealer has twice put in a new differential but the noise is back. The dealer now will not attempt another repair and has put us off until 12/10/03. We seem to have no one to voice a complaint to. The dealer gets one more chance under SC lemon law and is stalling. This problem has been noticed in Ford Explorer and Lincoln Mountaineer too.
