Was the "wobbling" from front or rear axle?
Slack in the swivel preload can be hard to with a normal check cause og weight of the wheel and hub.
Jack it up and take off the wheel and steering rod(s) and swing the wheel at the arm,the resistance there should be atleast 1,5 kg.I usually set mine to 2-2,5kg
Worn balljoints can also cause heavy wobbling,cause when they are worned you will get a "variable" track.
Loose steering box can also cause problems.
Bushes usually dont create heavy "wobbling" but makes vibration noises and clonk noises and makes the car wander on the road.
You could also check the brakes,if a spring to the pads are broken the pads can touch the disc and cause many intresting things
