Jeep Cherokee Wobble Death.... WHY ? ?

[Mubz]

Hi Guys,


I have a little problem with my newly acquired Jeep Cherokee XJ 1999. I'll explain the situation and welcome suggestions from experts.


Symptoms:


Driving at 100 - 120 Km all of a sudden front of the jeep will wobble and its not just the steering wheel entire car wobbles as if everything is going to fell apart. ( feels like you are in the epicenter of earthquake)


Applying brakes and bringing it back to say 60-80 Km it drives fine again.


History of Car.


Car was imported from US back in 2012 but kept in garage for 2 year and probably did 1 km at most.


Modifications:


1. Replaced all the fluids ( engine oil, power steering oil, break fluids, differential oil )
2. 2.5 inch rough country Lift kit
3. Bigger Tyres ( 255/55/R15)


Actions Taken So Far.


1. Steering shock replaced ( old one was damaged).
2. Wheel Balancing and wheel alignment.
3. Changed Spark Plugs.
4. Changed Air Filter.


Wheel balancing reduced the wobbling a little bit but not completely.


Someone suggested to change all the rubber bushes not sure if thats going to work or no but I need opinion from all the jeepers :)


Thanks in Advance.
