If you're getting steering wheel movement at low speed it's usually caused by either a bent wheel, a damaged or bent CV joint/half shaft or a bad tire.
If it's the tire or the CV joint you need to take care of it immediately before something bad happens. If it's a bent wheel, that's an annoyance that only you can evaluate, but it's not as much of a safety issue as the other two problems.
The steering wheel wobbles, because of the unconditional pressures from the ground that is adjusted at speeds when it reflects gravity.
Bent rim. You may rotate it to a rear wheel to reduce or eliminate wobble.
Could be alignment or air pressure causing pull. wobble is most likely tires out of balance.
The steering joints and connections are worn and need replacing Actually, the most likely problem is the tires. They may just need balancing. Sometimes the belts in the tires separate which causes a wobble. high/low spots in tires also causes a wobble. A bent rim can cause a wobble. Excessive negative caster will cause a wobble (alignment issue). Steering joints (inner and outer tie rods will not cause a wobble)
I'd check the CV joints first.
Worn-out ball joints in the steering linkage or suspension. This allows the steering angle between the wheels to vary, causing them to wobble.
If you are referring to the steering wheel wobbling whilst driving along, then you probably have one or both of the front wheels out of balance. If the wheel wobbles at a certain speed then it may be a problem with the front locking wheel hubs or a bearing problem.
becouse of bent rim or a bad spot in your tire .
Tire out of balance, defective tire, bent wheel, loose wheel, worn steering parts, worn or loose wheel bearing, worn suspension parts.
you obviously need to get it checked..that shouldn't happen
Wobble, shimmy, tank-slapper, speed wobble, and even death wobble are all words and phrases used to describe a quick (4 - 10 Hz) oscillation of primarily just the steerable wheel(s) of a vehicle. The rest of the vehicle remains mostly unaffected. Vehicles that can experience this oscillation include bikes, both motorcycles and bicycles, skateboards, and in theory any vehicle with a single steering pivot point and a sufficient amount of freedom of the steered wheel; this does not include most automobiles.
Tire out of balance, worn suspension parts, defective or loose wheel bearing, loose lug-nuts, or worn steering parts.
