You must have bad luck with trucks, I don't have any shaking all the way up to factory speed limiter around 100 mph(still has original factory control arms).
Doubtful. Luck is used as a definition when you cannot defend an outcome. How can you say my outcome is a result of bad luck if you have not experienced what I have experienced? I think that's called a guess..... the same holds true by me saying you have had good luck because you don't have a vibration.
Let's suppose for the purpose of discovery, my standards for performance are different than yours? Perhaps, I like a brand of tire that transfers vibration. Maybe I'm more sensitive to vibration due to the fact, I see the factory speed limiter as a starting point for speed not an end point. Maybe Montana roads are built differently and they assist in transferring vibration to the seat that can be seen and felt. Maybe I use my parking brake every time i park and my rear brake shoes are adjusted differently than yours.
Without you having any of those facts, or for purpose of discovery, any facts you want to include from your experience, and putting these into a multi factor equation, isolatioing variables and solving for an outcome, every response becomes a guess, including mine. There is no correlation to outcome. Thus a guess, attributed to LUCK, or as you described bad luck is still a guess.
However if you look at experience based on data collection and your experience is an N of 1 or anything less than a statically significant sample, its still a guess..
So from a fact basis, I own 9 vehicles and 3 motorcycles, 4 of which are Mopar products in my household. A 14, 15, 16, and a 22. In each of the 9 vehicles including the Mopars is a log book. Motorcycles are kept electronically due to weight. These books contain collected data on vehicle performance, upgrades, routine maintenance and the dates and times they were undertaken, examples include, gas mileage, codes collected, trouble experienced, modifications made and outcomes. Yes outcomes, did the change solve the problem.
I'm a big fan of ocham's razor.
Ocham's razor; is the problem-solving principle that recommends searching for explanations constructed with the smallest possible set of elements.
So in making my statement, My experience says the control arms remain a weak point and when i change them to something built differently the vibration goes away... how did I come to this conclusion. Data.... collected from my small sample of experiences recorded.
So please don't classify it as luck, it has
Nothing to do with luck.
However i can say, my experience is still MY experience. Based upon logic, sound research and outcomes, solving for the best possible solution with the fewest set of variables.
To conclude this very long response, I'm glad you have a well performing truck with factory parts. I hope it continues to provide you with years of trouble free service.
Have a great day!
