On Saturday I was accelerating to enter traffic on the freeway
when this loud clanging sound started. It terrified my daughter.

I wanted to stop the van immediately, but I continued on to get
off the freeway at the next exit. I noticed that the sound went
away when braking or accelerating quickly, so I was able to limp
home by racing and braking.

Can anyone confirm that this is a CV joint gone bad and if so
any tips on fixing it.

If not a CV joint then what?

TIA,
