What are causes of steering wobble on power assisted power steering?

Answer 1

the allignment from the tires, or the frontend of the car needs to be adjusted.

Sometimes low power steering fluid can cause this but more likely if you are aligned properly and/or it is not all the time wobbling at same speeds it can mean that your power steering pump is taking in air. To check for this have someone in the car while running. Have them turn the wheel all the way to the left and all the way to the right. Listen for belt slippage/squeal if none watch during this process with power steering cap off and see if any bubbles appear. The ONLY way for there to be bubbles in this tank is

a. Recently or still very low power steering fluid levels (you may hear a sucking noise if this is the case)

b. somewhere on the low pressure/suction line there is a weak seal, loose connection, or break in the line.

If power steering levels are good (check cap and see what type of fluid to fill with as the two options of power steering fluid can cause major problems if mixed or the wrong one is used it will be either power steering fluid or ATF [automatic transmission fluid]) then the next step is to replace the clamps on the rubber hosing check manual for details specific to your make/model/year Visually inspect for what appears to be loosest. There may also be a crack either in the rubber on the conecting side or somewhere along the hose visually inspect for crack. beyond this replace all rubber lines and clamps related to the suction side. If issue persists you may consider replacing the power steering pump.
