Jeep: wobble & tork bit, oil filter housing, track bars

Question
First, I have noticed several other complaints about side to side wobble, my cherokee '96 does the same thing.  At almost exactly 55 mph accelerating or not the jeep shakes.  The shake increases if I leave it at that speed.  I have replaced stabilizer and tracking bar.  It seemed to get better for a little while and is now back.  Any more ideas before going to mechanic.  

Also do you happpen to know the size of tork bit needed to replace oil filter housing o-rings.

Thanks alot for your response

Answer
I would take it back to your mechanic and see if the track bar is still in good shape, always make sure you use a premium or dealer track bar.  I have seen the value line track bars be loose when you put them on.  I would also have the tires balanced, if they are out of balance they could be aggravating or causing the shake.  I don't know what size of the torx bit you'll need, but I can tell you, you'll have to take a motor mount loose unless you find a really short torx bit.  Hope I could help out.
