After starting my truck, occasionally I hear a loud bang under the truck, seems to vary where it's comming from. Sometimes is happens before I start moving and sometimes it happens while driving. This is the weird part, it only happens once a day and at different times. I "think" it may be my parking brake sticking since I park at an incline at home and engage it each evening. I have new brakes in front but rears are at about 20-30%. Any other ideas?

 

What type of engine do you have?

 

I have the 5.7 hemi.

 

I tried searching for a TSB that could potentially be related to this, Thomc73, but unfortunately I was unable to find one.

Someone else on the forums who has experienced this before may be able to chime in with something different, but my recommendation would be to have this diagnosed at a dealership.

 

thanks.

 

I have a very similar symptom. Seems to happen after the truck has sat a while. I'll hear a bang or rather a dulled clunk that seems to come from the passenger side floor board after I start the truck. It can be some seconds after I start it before I hear the sound.

I'll set up my phone to record tomorrow when I go to work, hopefully it cooperates.

 

Do you use you parking break daily? Occasionally it happen when I'm driving as well. I was told it mike be my parking break sticking?!?!
