1st off I have a Dodge Ram 1500 2005 4x2 V8 4.7L with 104K Miles, Tires are around 1yr old 8k miles on them...

Well this is what happens when I 1st drive my truck it has no issues no shaking or loud clicking noise. After about 10-20mins of driving I can be speeding up from 1-15mph and the rear end will shake and make loud clicking noises (like metal against metal). Also does when I reverse or Drive around 45mph or 60mph and 70mph.....

I have replaced all my rotors and my breaks. All my tires have been rotated and balanced. I am up for all suggestions thanks

 

Have you checked your universals? Sounds like u-joints to me man.

 

No I have not but I am not to auto smart any recommendations on a way to check if this is really the problem?

 

If you get under the truck, grab ahold of the driveshaft and try to turn it back and fourth. If it moves more than a tiny amount then one of them is bad. You can usually tell because one end will click. Or both if they're both shot. Does this happen all the time or only when straight, turning, ect?

I had one go out on my GMC and it clacked when I took off, stopped, everything. Eventually the whole truck started shaking so I broke down and got a new ujoint :P

 

Turning and straight
I am going to go and buy the u joint today and install it this weekend or next week at the latest. But does it just go out over time or was it something I did?

 

they wear over time, the factory units are non-serviceable so you can't grease them, they adventually get grime and shyt in them and fail. No big deal it's fairly common to have to replace a worn u-joint. don't cheap out on them either get a good brand like precision and they usually come with a grease nipple so you can service them from time to time.

 

you might want to check your u-joints, also have to changed out your diff fluid

 

I bought the U Joint today got 2 of them to replace them both. I will post here with the update on if it worked or not going to try to do it tomorrow after i get done with work.

 

Well guys wasn't the u joint so now I'm about to lift the rear and take off the tires see if its the bearings anything elese u guys say for me to look out for?

 

Well I couldn't find anything.... going to replace wheel bearings next any one got any other ideas?
