Clunking inside my truck when ever I apply hard brake while pulling T@B

marty_m

I picked up a used 2006 T@B which is manufactured by Thor and uses Al-Ko mechanical surge brake. I noticed that from day one any time I brake my TV (2014 F150) relatively hard I feel a rather loud clunk inside the truck. I have suspicion that it's due to issue on surge brake for T@B needing an adjustment or something is wrong with surge brake component. I am having hard time locating a shop that is experienced with Al-Ko mech surge brake. Anyone have similar experience with TV "clunking" when ever braking hard while towing T@B with surge brake setup? Mind sharing how to diagnose or what I should check for? Thanks in advance. BTW to eliminate the slop between hitch receiver and trailer hitch ball mount I have installed Road master Quiet Hitch. This part did not help with the clunk issue when braking at all.

I have an 06 and have the same clunking.  Unless I'm mistaken, there is some play in the hitch ball that allows the T@B to move a bit forward.

Funny--I just finally got around to buying a hitch tightened about 10 days ago.  I didn't take the time to install it until day 2 of my current trip.  OMG, what a difference it makes!  I got the Quiet Hitch.

I have a hitch tightener called "Road master Quiet Hitch" already as I mentioned in my first post. It has made a zero difference. I have a small suspicion clunk could be coming from truck's drivetrain when ever it feels inertia of T@B. If brought my truck to dealer for diagnosis they are going to say it's the T@B issue and hand me a hefty diagnosis bill since this clunk only happens when I tow and brake T@B.

marty_m - Do you tow anything else, towing it without the clunk?

T@B is all I tow and all I have to tow.
