I have found out that the rattling chain sound I hear is the sway bar link that is busted on my truck.

I asked CarMax four years ago, when I purchased the vehicle to find and 'repair' this noise, but was told it was normal, and nothing was wrong.

Any advice on what I should do?

I don't want to spend $ that if I could possibly get fixed for free, or reimbursed for.

I'm sure somewhere I have the 'receipt' from CarMax, about this 'chain rattling' when I originally purchased the truck.

What could this sway bar link cause problem wise?

 

just take it out.
you dont need swaybars anyways :)

 

New links are CHEAP! And I'm sure there's members with links here they could sell ya for next to nothing. I've got 4 of them but none are going byebye since my brother and I keep parts to make our trucks stock should the need arise. Or shoot...hit up a junkyard or hit me up through PM. I got a few yards here with tons of 98+ rangers w/ intact suspension.

 

You know what gets me...

Of the three tire rotations I've had, new tires...

It took the brake guys to point out to me that the chain noise I heard wasn't normal.
(Mind you I mentioned it to the other garages. The guy at the brake store discovered it on his own, and investigated the chain noise himself.)
