I have a Ram 1500 V6 2007 and I'm getting a strange rumbling noise kind of like when you run over those notched strips on the freeway right around 20 and 30 miles per hour goes away once the speedometer goes past 30 goes away whenever I take my foot off the gas pedal but the minute I get around 25 to 30 miles per hour it Rumbles I get up to 35 miles per hour drive just fine perfect I read somewhere that someone else have this problem but not in a ram and they were advised to change the transmission fluid and it worked for them just had new rotors wheel bearings and brakes put on took them to a different shop to take a look at it a buddy of mine didn't have time to check out the rumble noise but he was able to tell me that everything appeared fine with the brake rotor and wheel bearing job

 

U-joints?

 

probably a bad u-joint or two. Check them with good light and a pry bar.

 

Ok thanks am i looking for play in the front end axel

 

If it happens durning acceleration, its probably the driveshaft. Unless you're in 4 wheel.

 

nah not a 4 wheel, and yes it happens during acceleration right around 30 mph
hope i can pull the job off
