I have install SLP Loudmouths axlebacks about 1000 miles ago. I have noticed a pinging sound in the back when I accelerate. I am using 91 octane gas and check for loose connections. I can not find out why this happening. Has anyone heard of this problem or know how to fix it? Any help would be great.

Thank you in advance,
Brenton

 

On mine, the left rear hanger rod was too long and was tapping up against the back of the bumper. All I did was loosen things up, and slide it forward so that there was 1/2" of clearance.

 

thank you... i will try it....
