I posted something about this about a month ago. I was wondering if anyone with a 1993 F-150 XLT had experienced this noise. I first thought it was the transmission. I now think it could possibly be the rear-end. It is full of fluid, I checked it. Is this a possibility that the rear-end is making this winding up sound when I take off and winding down sound when I come to a stop?
Any suggestions welcome. If it is the rear-end, is this good or bad?

 

stick shift or automatic?

 

rrich600 I'm having the same thing going on I brought it to a good tranny place and they said the rear end barings are going, but it does not sound like it's comming from there it sounds like the drive shaft. where the thing the holds them up is.

 

it is an automatic Frankenscagmachines.
and 1990Fordf150v8 it sounded like the drive shaft at one time, but the more I got to listening to it, it seems like it is coming from the rear-end. It seems to be growing louder over time too.

 

Hey, rrich600, I had the same problem on my 95 f-150 4x4, it was a loud whine on take off and stopping and then a dull whine when driving at constant speed. Took about a week to figure out it was coming from the rear end and found it by jacking the truck up and putting it on jackstands and then putting it in gear. Crawled under the back and listened to the rear end and could hear it whinning. It was the inner bearing making noise and needed replacement. I had to have my dad help me because you need to take the ring gear out and and then re-set the ring gear lash which I didn't know how too do.

 

Thanks Big Blue95, I have a feeling thats probably what it is.
It will probably get louder and worse with time too. I will have to check into getting it repaired.

 

Also, if the bearing is your problem, remember to check the front seal on diff. housing every once and awhile. When mine was going bad I was told that once that seal started to leak that it was time to park the truck because the bearing had gotten to much play in it. I fixed mine (with my dads help) only about a month after first hearing the noise so mine never got that bad.

Do you have any idea how much this repair will cost? What does a new rear-end cost or re-built?

 

Well, if you can do it yourself or know someone who can help you do it the parts are pretty cheap. I bought the whole overhaul kit from Summit Racing for about $140, bearings, seals, shims if needed, even the outer wheel bearings. It was a Ratech kit and it worked out real well, nothing was missing and with my dads help it took about 5 hrs.
Before I decided to work on it myself I talked to the owner of the shop my girlfriend takes her Honda too. Her family have been taking their cars to this shop for a long time. They didn't do that kind of work but he referred me to a place he recomends and they told me about $550 - $600 to start, just for the bearings, seals, and races to be installed. He told me it would be more if they found something else wrong. This is in Dallas though so it might be cheaper in your area. I thought it was alot of money and didn't even bother calling around after that. Maybe you can find it cheaper but I also recommend you take it somewhere that people think highly of because if the person doing it doesn't put it together right it can ruin your ring and pinion gears, which are like $200. My dad has forgotten more about cars then I will ever know so I trust him. I don't think there is a piece on a Ford truck he hasn't fixed at least once.

 

I have the same sound on mine. 87 ford 2 wheel drive. Of course though, its also -35 degrees here.
