Hi Steve,Yes sir, whenever I have my wheels balanced, I make sure the tech starts over and removes old weights.
Phil since I have you on here, wanted to pick your brain regarding my highway vibration issue. I just remembered, that when my buddy let me borrow his stock Ford wheels and tires, for the first test I only swapped out the rears only and took for a test drive. My truck appeared to ride smooth. Then I went back and added the front and it went to crap. I just remembered that his were smaller tires than mine, since my front ones were taller and his rear ones smaller, did that possibly make an angle change in my driveline which corrected my vibration? Just a thought since I’m running out of ideas. Going to try this test again soon.
It is bit puzzling, but the force difference between your bigger tires and his smaller tires will be minimal...What might bubble up is an out of round tire or rim.... Really need the frequency of the vibration as is will lead to the culprit. If you can determine which end of the vehicle is generating the imbalance, it might also help. As an NVH technical expert, you can now see how difficult these problems are and the time we invested in the field to resolve. You walk in blind and have to figure out what is going on...Dealer Tech and the customer think you will solve it in a minute or two...Simply not the case.
In your case...do some home work...drive at a steady speed...vibration? Okay...increase speed? Vibration at the same level? Your assometer might sense the change in frequency. In all cases, note the vehicle speed and engine RPM if you can.... a bit of work and may not help, but please consider giving it a whorl.
Responed to me with @P. A. Schilke so I get the flag to read the post...otherwise I might not see your answer as I cannot devote the time to this website due to the number of posts and my change in my family situation that limits my time on these forums.
So far the @P. A. Schilke has limited success..... I simply cannot do PMs...it flooded my mailbox...
best,
Phil
