I installed full traction track bars front and rear on my unlimited rubicon around a month ago. They are starting to squeak on almost every bump I hit. Has anyone else had this problem with this paticular brand? Any suggestions
would be greatly appreciated as well. Thanks.

 

Grease the joints (especially the upper hard plastic one) liberally. You will need to undo it and drop it in order to do so properly.

I was skeptical that this would work, but mine's been silent for a couple months now since doing this.

 

Yup, what he said. You need to apply white lithium grease to the upper frame mount black bushings and metal sleeve. Click on the link below and read Step 2 for more details:
