I've been reading a good bit on the death wobble phenomenon and from what I can gather, it appears that it's due to OEM bolts either not properly torqued or losing torque spec along the way.
Suggestions range from performing a re-torque on all the suspension bolts to replacing all the OEM bolts via a kit or gathering the bolts independently to replace.
My questions are this.
- Is this problem still applicable to newer JK's? It appears that this began somewhere around mid 2010 models. In the threads, it appears that the 14mm track bar bolt is still in use from the factory and that this issue with the trackbar bolt continues. I purchased a 2013 in April. Should I be concerned?
- Is the biggest contributor not having the 9/16" bolt in the trackbar? Should I begin by first just replacing those bolts?
- As for the other bolts, why replace all the bolts if a re-torque of the OEM bolts will basically do the same thing? Is there an advantage to the grade 8/9 bolts over the OEM bolts that will ensure a longer term solution?
- Is it possible to purchase the bolts for the same or less than one of the available kits online? Has anyone successfully done this at a Home Depot or Lowes?
- Is there any advantage of one kit over another? I read on another thread that the Northridge 4x4 kit is about $40 and seems to be the most affordable option. I assume a grade 8 bolt is a grade 8 bolt, regardless of where it's from?
Sorry for all the newbie questions. I look at this as a priority preventative maintenance item if it's applicable.
Thanks in advance.
