Thump!

This may be a strange question....I can hear a muffled THUMP! when I put my truck into drive. This doesn't happen all the time. Sometimes as I'm leaving from a parking spot for example. I put it in drive, begin to pull away then sometimes I hear that THUMP! noise. I have a 03' F250 4x4 CC V10. Any ideas or suggestions?

That makes sense! I would have NEVER figured that one out. Thanks for your help!

Thump!

Hi dmoto,

I am waiting for my F250 CC LB V10 to arrive and was wondering how you like your truck so far. I'm glad you brought up the thump as I would probably freak a little bit if I heard that on my new truck. Take care.

Thump!

I had this problem today! A thud... clunk... some sound that I just couldn't place when I took off... It turned out to be the Cheby Blazer chained to the tailer behind me!

If you do a quick search of this forum for "Thump", you will find several threads on the subject.

Thump!

It is the AC......I was having the noise until I realized it didn't happen when my AC was off.....It makes the same noise as when I run over a Dodge or chevy
