Im dumb lol clunk after disconnecting the battery?

Ok I did the Fog light mod (love it btw) DRL mod is next, but after disconnecting the battery and doing this I now feel a clunk like right after pulling away from a stop and sometimes when stopping.


So :WTF?

Was this here and I just didn't notice it before or did I do something to the computer and it needs to be reflashed or what?

Its very faint, Im like 99% sure it didnt do this before maybe Im just overly worried because I owe $$$ on her lol.


Thanks

 

I doubt the ecu would cause a clunk after being disconnected. Explain the clunk more

 

Ok so when I pulled out of my drive way it felt like a driveshaft clunk. Like it was lose if that makes sense.


Then I pulled to the stop sign and felt it again very very faint clunk.

Pulled out very very faint clunk again in the rear for sure, then stop light another clunk.


Then I parked at store went in came back out and did not feel it or hear it but once on the way back.

I know there is nothing in the back of my truck to make that noise, I do have a tow strap in one of the compartments but I have never had a problem before.

And for some reason I want to say it feels like the drive shaft.

 

Ok so I took it for another spin, (its kind of concerning me no clue why)

I noticed the clunk is gone (i made sure the tow strap was not moving around), and now it is just down shifting harder then usual. Eh doesnt bother me.

Thinking I might have reset the computer, Ill have the dealer check it next time I'm in see what they say.

I think Im just overly cautious because this is my first vehicle I owe money on and I want to take care of it and make it last lol
