I have a 1998 Grand Cherokee Liminted. Their is a vibration on the front wheels and the steering wheel shakes. Had it allined and tires ballenced.Everthing is stock.Put new pads and callipers on back.
Also, the sun roof will not open. Don't know where the fuse is for this or could it be something else?
What could my problems be?
The shaking just happens at about 50mph, plus or minus (1)mph...

The sunroof is controlled by the Sunroof Module #13, located in the overhead console as part of the sunroof assy.

it sounds like its coming from your drive line.....you might have a bent drive shaft

I have a 97 ZJ and i have the same problem! The wheel starts to shake at 50 then right after 52 it stops. I just got new wheels put on it and u would think they would be balanced but i know that they did not do a good job on mine because it happon befor when i lost a wheel wight. Got it put back on and it was fine. You mite have lost one or they did a crap job.

I would take a good look at your tires. low speed shaking like that is most often caused by a seperated tire. Lots of time the tires look like they have tread on them and still should be good, but the compound on tires as they were get harder by design. I had micilin tires that looked really good and never wore out, but were lumpy and bumpy just from being old. Anyway sounds like you may have a bad tires.

If I rotate them, front on & back on front, think that will tell anything?

How would I get the drive shaft checked out? The Jeep has never been off road.

Cherokee_Dave

How do I get to it?

Well it would be a good inexpensive way to try. If you can feel its in a different area then you will know. As long as you dont' have one on the back that is bad and your just moving stuff around. don't hurt anything to try except time.

I don't think it would be a drivline issue because its most noticble at lower speeds. Drive line vibrations are normally quite fast feeling and most often felt when going faster they get worse. When you feel it, try to imagine the speed at which it compares to. Tire rotation or engine speed.
