'99 Sub 2500 (5.7L/4l80E/SF14B) high miles, but well maintained mechanically.

Brakes were excellent & smooth... until I swapped on a set of Dodge rims (rejection? :D). The center hole in the rims have a larger hole (lug-centric?) than the stock Chevy rims (hub-centric), so I took my time tightening the lugs and centering the rims. There was a noticeable difference in the ride quality... possibly the tires, but have read about folks fighting with vibes/etc when swapping rims on pavement pounders. I did a brief search and couldn't find any hub spacers thin enough to make up the difference...

Ever since, I get an intermittent shudder and can't really tell where it's coming from, though I suspect the front...

Am I dreaming or could the different rims be the cause? Or is it something else? :confused:
 
Did you use the proper lugs for the taper of the wheel's seat for the lug nut? Compare the new & old, and see if there's a difference?
 
If the dodge wheels are not the same taper in the lug nut hole, that could do it.
 
Binggo...actually a lug centric rim on a hub centric set up with the wrong lug nuts is unbelieevably dangerous.

What will (not can but WILL) happen is the rim will vasscillate as it rotates (thats sounds dirty) and the lugs will back them selves offf, by the time you feel this you may be lucky if you can get stopped. There also is often a considerable difference in the lug size/strength...my first choice would be to go back to hub centric rims if possible....

I am probably over stressing over this, but it cost me a good friend right after high school been a pet peeve for the better part of 2 decades now...
