Alignment problems

What would cause the front end not to stay aligned and also give "bumping" or slight "loose" sensation in the front end. Worn out tie rods? track bar ? TIA for any advice

I'm no expert......

However, there does seem to be some durability problems with the front ends on these XJ's, esp if flexed seriously. The Lower Control Arm bushings will split sometimes among several other things. Need to closely ck all suspension connections carefully. Believe this is the main reason for the 'Death Wobble' you see mentioned on here occasionally.
