    Thread: Front end clunking

    1. 08-13-2019 09:40 PM #1
      For the life of me I cannot find the cause of this clunking noise. It's pretty popular in most VWs as I have found out. And yet no one found definitive answer as well. The clunk continues. I've changed the rearward bushing which was in bad shape. Changed inner and outer tie rods. The inner was a bit loose. And changed both sway bar ends. Sway bar bushings look good. Ball joint good. No play in lower control arm. Strut is tight. Dog bone bushing has some play. But no metal contact when I shake it hard. Take a listen. Any ideas will be greatly appreciated

      WOW thats what mine sounds like also! i have been chasing this sound for months with no luck...

      I have replaced struts/Strut mounts,drivers side axle,all motor/trans mounts,dog bone and upper and lower sub frame mount,sway bar end links,rear control arm bushings
      I notice it a lot on gravel roads.. I really dont know where to look anymore.. very frustrating. I was maybe thinking of looking at the rack? steering feels fine though.

      Thanks

      I might be off base on this one so forgive me, but I too sometimes hear some clunking from the inside. I only noticed it when i have the AC/HVAC system is on. when I turn it off, it disappears. Again, apologies if i'm way off base.

      Thought it could be anything as well. The AC was off during this video. The noise has been going on for a while. Even in winter. And no reply is too off topic. Thanks

      Not yet. That may be next. No effect on steering

      i may try the sub frame bolts and see. There is a update kit with a spacer. Not to expensive or hard to do.

      What is the spec torque for the sub frame bolts? VW doesn't allow a Haynes manual. All things I am willing to try I have heard others did to no avail. I will try to bolts a shot

      Check your brake carriers too. I had a carrier bolt back out and it sounded just like that, until the bolt came out all the way and then in was a very different sound
