I have an '05 Ram 1500 QC that i purchased used with 26,000 miles on it. I've been noticing when I'm at a stop, and the wheel is turned and I slowly go in reverse my entire truck shakes. It feels like the shaking starts in the rear axle, I am not positive on that tho. Sometimes this happens when I am turning from a stop going forward, its just not as violent as the reverse.
Anyone have any ideas as to why this would be happening?
Thanks

 

Oh, my truck is a 4X4 5.7 without any modifications if that makes any difference.

 

Sounds like its in 4WD on dry pavement.

 

this sounds similar to what my truck does but mine doesnt shake. if i reverse on flat ground and turn the wheel usually to the right it sounds like the rear or something makes a deep hum sound.

 

I don't know but I have to agree with kenihemi

 

sounds to me like you need to change your diff fluid.

 

Yep, rear differential. My was making the exact same noise/vibration in the same way. Slightly turned wheel going in reverse would create a deep hum/vibration sound.

I changed my rear diff fluid, checking to make sure nothing was damaged in the gears. I also added a little extra of the LSD additive, my noise is completely gone.

 

Hopefully just changing the fluid in the rear differential should stop the vibration. Ill change the fluid Monday.

What is this LSD additive?

Thanks for the comments/solutions

 

limited slip differential additive. Its a small tube that you add before you add your gear oil if you have a limited slip diff. although most good synthetic gear oils already have the additive in them. If you do have limited slip its good to add it, if you dont have lsd, its ok to use the synthetics that have it in anyway. you"ll be able to tell if you have lsd if you take off your diff cover and dont see all the gears. If you can see them all its just an open diff.

 

thanks ryland, ill check it out.
