Hey everybody, theres like a whineing noise comming from my rear. And it gets louder as i go. Could it be U-joints going bad or does it mean my rear end is gonna blow?

Thanks..

 

id check the fluid level in your differential if i were you

 

Why is your Wife at the rear of your truck? Sorry had to ask. But seriously, check the fluid, check U-Joints. My rear one siezed and obviously seemed tight, but it was the culprit. I had to work and didn't have time to look at it too closely myself so I took it to a local shop, (A guy who I knew) and had him replace the rear u-joint, and service the diff. It cost me $200, parts and labour

 

Thanks, i had a similiar problem with my other truck. The rear was humming and finnaly blew. After i got it fixed, i had a u-joint going bad and it was humming. But i was told not to worry about it. I just got done driving it so i have to wait for the fluid to cool down to check it. Thanks for the advice everyone.

 

Ok, i found out that it isjust my tires. They are making the "whining" noise i was describing. My friends 2 wheel drive ram was making the same exact noise and he said that it is his tires.

 

Holy crap thats funny!!

 

I was thinking the same damn thing LOL.

 

Two things about the whining noise:

2 years ago, I had the dealership replace the pinion gears in the diff because they were gaulded. That worked for a while, but the noise came back.

At 45-60 mph the noise is most noticeable. It is a rear end problem, but I don't know if it's a U-joint because the rear-diff work corrected the problem for a while.

Another idea: whiney fuel pump? The noise occurs only when my 2003 Dak QuadCab 4x4 4.7L is given gas in the 45-60 mph range, and the noise does not occur at all outside of that range.

Additionally, 1 year ago, I went to a different dealership and was told by a service tech (who may or may not have been a jackass) that there is a TSB out calling for Dakota owners to gauge how bad the noise is by this method: If you can turn up the radio to drown out the sound, it is considered within normal operating limits.
I would counter: So are we talking Aerosmith or NPR "All things considered," because I can turn either up and both can be on the radio...

???

 

o yeah hes definately being a jackass, pop the differential cover off, check the condition of the ring gear cause if theres anything wronf with the pinion, it will definately show up on the ring gear *i beleive, someone come in and correct me please*, check fluid condition, and change fluid.. thats your best bet w/o going to a mechanic or a dealership

 

factory or aftermarket? lol thats some funny ****
