Car Forum / Ford / Ford Explorer / September 2007Rear end whine on '03 Explorer
I'm coming up near the end of my extended warrantee on my '03 Explorer and I'm hearing some whine from the rear end. Is this subject to a TSB or is it a known issue? I'm at 70k miles and have never towed anything with this car. dave > I'm coming up near the end of my extended warrantee on my '03 Explorer and > I'm hearing some whine from the rear end.

Search the group and look about a year ago. Yes they know about it. I don't know if they will at 70k though. Good luck Thanks Richard. I'm hoping that this is covered under my Ford Extended Warranty. dave >> I'm coming up near the end of my extended warrantee on my '03 Explorer >> and [quoted text clipped - 9 lines] > they will at 70k though. > Good luck >Thanks Richard.

If not, then go to some non ford specialty shop that does rear ends and ask them for their opinion of the noise. Most likely they will say it should not make it. Have them do the work AFTER getting it authorized by the warranty company. >>> I'm coming up near the end of my extended warrantee on my '03 Explorer >>> and [quoted text clipped - 9 lines] >> they will at 70k though. >> Good luck I have a regular mechanic (oil, brakes, alignments, etc.) and he noticed it right away. In fact, he had an Explorer of his own that required a ring and pinion gear replacement. My warrantee is the standard Ford Extended Warranty and it runs out at 75k so I need to get this addressed soon. I'm not sure if Ford will pay another shop for their warranty work. I'm also getting noise from (according to the same mechanic) my brake booster (vacuum boost?) as it is now making a rubbery squeek sound as I press the brake pedal....it never ends, huh? Also, if anybody else is still reading this thread, have you guys/gals had repeated problems with door switches (the ones that indicate a door is ajar)? I've had to have my driver's door switch replaced about 4 or 5 times since I've owned this '03. They seem to last about a year before they start to act up. Is the door switch on these Exploders located inside the door? They don't use the old-fashioned dead-man pin switch like I'm used to. dave >>Thanks Richard.

When a switch acts up, get a spray can of electrical contact cleaner (or WD-40 if you are lazy) and spray into the latch mechanism from the rear edge of the door. I am talking about the mechanism that mechanically latches the door to the striker mounted on the body. Flush it good. The switch should start to operate properly again. I don't know why, but it seems a lot of grease and grime work into the switch via the latch mechanism and interfere with the proper operation. My later Fords have not shared this problem. I thought they had corrected it before 2003, but I guess not for all models. Ed Thanks so much, Ed. And thanks for the TSB in your later post. Tell me this....how do dealers feel about customers who come in with a TSB in their hot little hands? Do they appreciate the legwork that you've put in or are they annoyed that you are telling them how to do their job? Just curious. Is the switch itself located back near the latch mechanism? From your description it would appear that it is but I've never actually seen the mechanism. I got a little "testy" with the last service writer dude when, after my 3rd replacement switch (and the loss of my hours spent in their waiting room), I asked him if I was going to have to expect this same failure every 10-12 months. He wasn't very helpful with his answer and claimed that they were using the correct parts and that "sometimes parts fail". I can understand that, but this is such a chronic problem and it affects (or CAN affect) the entire car when it fails. If you think that's overstated, do a search of the archives here and see what happened when this same dang switch failed about a year ago right in the middle of a battery replacement!! THAT one kept me hopping for days. dave >> Also, if anybody else is still reading this thread, have you guys/gals >> had repeated problems with door switches (the ones that indicate a door [quoted text clipped - 17 lines] > > Ed > Thanks so much, Ed.

See http://info.rockauto.com/Motorcraft/SW5138.jpg for a picture of the switch. I believe crud contaminates the switch pluger and keeps it from moving as it should. Spraying WD-40 or Electical Contact cleaner into the latch "moves" the crud and allows proper movement. As for Dealers and TSBs. These are not secret documents. You can get a list of TSB for your vehicle from http://www.alldata.com/ or from NHTSA. Once you know the TSB number, you can search for it on the web. There are many sites that post at least some of them for free. If you are willing to pay, Alldata will sell you a subscription, or you can purchase temporary access to the TSBs from Motorcraft (see http://www.motorcraftservice.com/vdirs/retail/default.asp?pageid=&gutsid= 0. ). Some dealer willingly share the infomration, some would rather keep you in the dark. Most good service writers are aware of common TSBs (like the rear end whine TSB). They may play dumb, but they have access. Given the amount of information on the Internet, no service writer should be surprised if you show up with a copy of a TSB. They may play dumb, but it just an act (at least I hope no dealer has anyone that dumb as a service writer). Unfortunately, there are noT always TSBs for common problems. Ford has an internal service information sharing service, OASIS, where problems and solutions are shared. I find www.flatratetech.com a good palce to get additional information on problems.

They didn't say a word about it except " You probably know some of them have a problem, we will take care of it" I had about 500 miles left on the 36k warranty.

Since I thought I'd only be wasting a day or two at the Ford dealer on the rear end, I figured I'd also get a couple other annoying issues taken care of at the same time. So, instead of a day or two, the '03 Exploder was in the shop for four days! Here's what they did (all covered under my Ford Extended Warranty less $50 deductible): 1. Rear end whine - the mechanic who did the road test with me could hear the noise, but thought it would only be a rear bearing. However, they replaced the ring and pinion along with a bearing and shaft seals. Noise gone and it's dead quiet now. 2. A/C or heater blend door - this thing had been giving me problems for quite a while; it would allow a TON of air to be sent to the defrost vents instead of the regular vents; apparently this involved taking a lot of the dash apart and replacing the housing too; I'm guessing that this repair was the one shown on one of the DIY sites where they show how to repair the bad shaft, right? 3. Squeak in the brake pedal - I thought that this was simply some rubber boot rubbing against a metal shaft that would make a rubbery squeek sometimes when I'd apply the brake; my regular mechanic thought it was the vacuum booster; they replaced the master cylinder instead; no real difference to the feel of the pedal or brakes, but the darn squeek is gone All in all, I think I got my money's worth out of my Extended Warranty and I still have about 4,000 miles left on it. I still have the sporadic and annoying door switch issues and (related, I think) I have an issue with a darn warning chime going off while I'm driving down the road OR I'll get a warning light telling me that a door is ajar OR the doors will do their "automatic lock" thing after I've already been driving several blocks instead of right after the car starts moving. It's these darn intermittent electrical problems that are the hardest ones to pin down for the dealer to fix, 'ya know? dave > I'm coming up near the end of my extended warrantee on my '03 Explorer and > I'm hearing some whine from the rear end.
