Just started having vibration at cruise speed
and it really is a pest. Just rotated tires
after a couple of months and don't remember
this much or even if it did with other tires
on the back.(lot less rubber almost a 1/8)Has
any had the problem an found what it might be. I will put on the drag radials and test
to see if it is that group of tires that is the cause.
cause.

I've just noticed the same problem. It seems to be most noticeable at 80 to 85. At 90 it doesn't seem as bad. I also noticed it seems to be more noticeable on a slight grade up hill. Anybody know whats up?

 

You did rotate them front to back and back to front and not crisscross right?

I also have some vibration, although it occurs at higher speeds above 90mph. Now i just installed the the lowering shackles, should i replace them with the stocks before i take it to the dealer dont want to have an warranty problems. By the way the vibration was there before. One the i notice is when i frits notied it i was doing 110mph, then i noticed it at 100mph and it just kind of seems to keep getting to lower speeds. Thanx for any help.

I rotated mine front to back. I sure hope it's not a plug or coil. But now that you mention it it is taking a little longer to start too.

 

I had the same problem with my 2000. It ended up being 2 bad plugs, a coil and i still have a bad injector that has been on B.O. for weeks. After these were repaired
i lost the vibration. Hope this helps...
