Suspension Knocking/Rattle Over 80mph
 

Just picked up a 2012 Bayswater MCS with 36k miles... I haven't had a chance to post in 1st gear yet but just noticed this issue the last two mornings.

When getting over 80mph I'm hearing a rattling/knocking kind of sound coming from the front driver side. I'm not feeling a vibration anywhere, just hearing this sound. I'm not hearing anything unless I'm over 80 which doesn't happen a lot. It's not a steady rhythmic sound but for random/oscillating.

Everything is stock suspension wise to my knowledge. Lug bolts are tightened to stock torque specs.

Ideas?
