Hey guys,

Well for a little while I have had some vibration at slow speeds 5-25 mph with my 98 GC. It is stock, but I do have mud tires on. Also one of my sway bar links broke a little while ago, and I'm just now getting around to changing it out.

Could either my mud tires or my broken sway bar link be the cause of the slow speed vibration? Once I hit 25 or above it seems to go away. Other than that I have had no diving problems, just this annoying vibration that can sometimes vibrate loose things in the cabin.

Any ideas on what might cause this? Could it be a front end problem, or a drive train problem?

Thanks

Do you feel the vibrating in the cabin, like through the pedals or steering wheel? Or is this something you are just hearing? Does it change with throttle load? Try to be a little more specific.

I feel the vibration in the cabin, through the steering wheel, but also in the seats, and just about anywhere. It doesn't really change noticeably with an increased throttle load, if anything it lessens if I increase it.

When I'm breaking or slowing down to the under 25 MPH range I also notice it in the cabin quite a bit. But again, when I'm over about 25 MPH I feel/hear nothing out of the ordinary.

Mine did something like that with with my old mud tires they had super agressive tread and when slowing down to a stop light it would vibrate a little, and they would also hum realy loud over 45 mph, so i bought some used bfg a/t's for street driving and it stopped. The boken sway bar link i dont know if that has anything to do with it, i drove around with out my sway bars connected for the longest time and nothing like that happened.

I have had my muds for about a year now, and get them rotated regulary. Their wear is not really uneven, so I don't think that these are the problem.

I was under my jeep yesterday trying to replace my sway bar link(damn rusted bolts), took at look at everything and I really didn't notice anything out of the ordinary. I also took more of a note that the shake/vibration gets pretty violent when I slow and break from 25 MPH down to 0.

If i apply normal breaking when im traveling above ~25 MPH nothing feels out of the ordinary till I hit 25 mph and lower. Very weird. Any other suggestions?

check your exhaust running across your trans support, could be your exhaust hitting it causing the vibration threw everything.

im having the same exact problem and havent been able to figure it out

i know my exhaust is making contact with my claytons crossmember so ill check that out

Check what your Jeep is idling at, mine would idle around 500-600 and cause some major vibrations, not sure if your having the same problem, but that's what mine was, if you change the idle to about 1k it might stop
