When driving at highway speed at 55 to 60 or even 65 mph. back of 1995 jeep cherokee sport xj shakes violently... not a wheel out of balance im sure of wheels were recently balanced... what else is wrong...

 

I had the same problem it was shaking like crazy at 60 and the I put a 4.5" lift in and it started doing it at 30. The problem was the front driveshaft. I took out the front drive shaft and the problem went away. I have since purchased a brand new drive shaft and installed it and still no problem.

 

have you recently put a lift on your XJ? Sounds like bad drive line vibrations, have you checked your angles?

EDIT: x2 on the ujoint. If you haven't recently done any work to XJ and it just started it's probably a bad rear u joint.

 

could be some bad u joints or if you have lifted it lately that could be causing your issue

 

STARTS SHAKING VIOLENTLY AT 55 TO 60 TO 65 MPH.... WHEELS ARE BALANCED AND THERE IS NO LIFT KIT OR LOWERING KIT ON THE JEEP... THE JEEP IS A 1995 JEEP CHEROKEE SPORT 4.0 LITER... EVERYTHING IS STOCK... WHAT IS WRONG WITH IT.... GOING ON LONG DISTANCE TRIP HERE SOON MUST KNOW QUICK...

SHAKES IN BACK.....

 

have you checked your rear and front drive shafts make sure the ujoints are not bad

 

most likely rear u-joints. Just had to do all of mine. Generic replacement parts are around $25-30 at the local auto store for doing it yourself. You'll pay more for higher quality joints and obviously Labor charges if you have your local Chevron station do it.

 

well... they are stock and like i dont know what the u joints look like.... and what else could it be??

 

they are the pieces that look like an x in the drive shaft this is most likely your problem are your shocks stock as well or have they been replaced any time soon (oh and the ujoints should only run you about 15 bucks a piece unless you get some off road super joints or some thing like that )

 

you want more? Well, I also had a messed up driveshaft that needed to be rebuilt...for a pretty penny. Could out of alignment. Just take it to the shop, and tell them the problem. It's most likely u-joints (as was the concensus with my problem and yours). If you can't do it yourself or are going out of town and don't have the time (as I didn't) just take it to the shop.

BUT supposedly, it's fairly easy to do with relatively basic tools. Just thread search and you should find a how-to!

 

like i said before i would like to have pictures of them if you have any and the shocks are stock to .... everything is stock in the jeep....

 

here take a look at this http://www.off-road.com/jeep/reviews...t/CTMvsOEM.JPG you most likely need to replace them and your rear shocks

 

ok so what all must i replace... for the jeep to stop shaking

 

most likley the rear shocks and ujoints this should fix the problem you might want to take it to some one to have it done

 

u-joints...if it doesn't work, then rear shocks. after that...you got issues like I had LOL
