Problems with 2000 Jeep Grand Cherokee WHEELS

While driving at speeds around 48 to 51 mph, you can feel the steering wheel start shaking sometimes if you take your foot off the gas petal it will stop but more than not it will go into a violent shake to where one can hardly hang onto the steering wheel. you have to try and get safely to shoulder and stop. then you can drive away but when speeding up to merge back into traffic it does it again. when you just cant take it anymore you exit the freeway just to drive the city streets to where you get the small like shaking in the steering wheel. these past 2 weeks it seems to be happeing more often. i have had some work done as to what my guy thought it could be for it to not be fixed. i also now have the annoying air bag light coming on and beeping while turning any direction corner. i really like the jeep but i only work part time and my fiance passed away 2 years ago before his passing he bought the jeep so i would have a safe vehicle to drive. i do not feel safe driving the jeep but it is the only one i do have now..parts and work done as of february of 2015.....3 tie rod ends replaced 2 lower one upper on passenger side, 2 new tires because i was told that is what was causing it., a rear driver side wheel seal, a valve cover gasket, 2 sets of front brake pads and rotors cosing well over 1300.00. and still have this violent shake. i can not afford to buy a different vehicle so please tell me what to stop the shaking forever.

Tie rods, wheel bearings, ball joints, fan clutch, shorted engine compartment wiring harness, fuel pump assembly all gone wrong from time of purchase; january 2000/brand new to sept. 2006...some pd. under warranty others after 2004 not; even though the defects usually do not happen to a jeep grand cherokee/fully loaded. the last straw was the ball joints; we asked if some form of recall should of been done and then asked for a reimbursement because my wife's' 2004 jeep liberty limited had a recall on it's ball joints/lower ones so after having mine replaced last friday 9/15/2006 we asked about the grand cherokee and it's ball joints; we also updated on all the defects we've had to correct and wondered if it wasn't a expensive lemon...$35,000.00 is what i paid. we called chrysler main customer service and was only told were sorry, the age of the jeep and past warranty...what does that have to do with all the past defects since 2000 and the fact we tried their customer service in 2002 and got no where again. no matter the age of the vehicle...safety is safety. and if ball joints go bad for no reason and have to be replaced then, it should go as a safety concern for all their vehicles. *jb

Right front aluminum wheel rims gets too hot to touch. rims seem to get hot according to temperature outside. dealer can't duplicate problem.*ak the right front caliper would not totally release heating the rotor and causing vibration, the caliper and rotor were replaced which remedied the problem. *slc
