Next, he swaps the front tires side to side, to see if the problem moves with the tire, just as any good problem solver would. It doesn't move...he still has the vibration in the same spot.

Now, keep in mind he has had 2 different tires mounted on that corner of his jeep, and he still has the vibration in that corner of his jeep....so, what does he do ??


Ok........using your logic, he now must go buy a new rim & tire and put it on in that corner of his jeep, as that is the only thing that will fix his problem and make the vibration go away.
Forget trying to look and see what else may be causing or contributing to the vibration....like maybe wheel bearings, ball joints, bent axle, bent rotor, sticking caliper.....no, it's not any of those.......only a new rim & tire will fix it.


Silly right ?? Well, it's no different than saying that a new driveshaft is gonna fix his problem and nothing else could be causing or contributing to it. I mean he did try 2 different driveshafts, and still had a vibe. So the chances are good it ain't or ain't just the driveshaft. I never said he couldn't use a new or better driveshaft, but I did say it is likely not the only problem, and he may not need a new one.


That's all I've been saying all along, is since he has a vibe with 2 different D/S's, he needs to check to make sure it isn't something else as well before spending coin on a new one.


And if just a new D/S does fix it for him...I'll say good for him - problem solved, Jeep Driver was right.....but I won't apologize or say I was wrong, because nothing I have said or suggested to help troubleshoot the vibe and what is causing it has been wrong.

Just like the tire scenario above....when you have the same problem with 2 different replaceable components...usually that component ain't the problem. Be it a tire/rim or a driveshaft.


And HYRYSC...if you have any more questions for me....IM me...be glad to try and help, but I am done with this thread. I don't mind trying to help, but it's not worth arguing over with someone who won't listen.
