What would cause a thumping noise like a flat tire when turing to right and when you go at a slow rate of speed with you feet not on the pedal or brake?

Answer 1

I have a 2001 Dodge Ram that had a similar noise. It only did it at low speed and usually when making a right turn such as turning into a parking space. I checked the entire front end and found no problems. I finally decided to check the rear end fluid since sometimes noise can be be misleading as to the source. I had about 40000 miles on the truck and the fluid level was good. I decided to change to rear axle fluid anyway. After a complete fluid change , the noise went away and no more problem. One thing I did do when I changed the fluid was use Mobil 1 synthetic and also some Lucas Oil Stabilizer. I am a big fan of all the Lucas products after seeing a demo at the local auto parts store. If you are interested in these products here is the website with some information: http://www.lucasoil.com/products/index.sd . Whatever you use just make it sure it is the correct lube. I hope this helps you out with your problem. I'm at 54000 miles now and still haven't heard any noise. Best of Luck to you.
