If the TSB is for swapping out the track bar, go for it. The results are reduced side wind sway, and better mid-corner stability. It's a worthwhile update.We have a culture where modifying Jeeps is cool. And it's really cool to modify a Jeep to make it stronger and more capable.
What's not cool is paying to modify a Jeep to correct a problem that's in the design or making of a Jeep.
When I worked at 3M Canada I was encouraged to ask questions as an engineer. First: "Did it ever work?" If it did, then "What's changed?"
My Jeep is a lot better since the steering gear was changed.
I feel badly for those people that have had the change done and it's as bad or worse.
It was FCA Jeep Canada Customer Care that suggested I change dealers for service. I'm glad they did.
Now there's a new TSB I have to decide whether to get the work done on that TSB. I've got some thinking to do...
