How to Perfectly Solve the Steering Wheel Sticking Issue in the New Excelle?

[MatteoLee]

When turning the steering wheel during normal driving, a "squeaking" sound can be heard, and the steering wheel exhibits sticking. It is necessary to visit a 4S shop to adjust the toe-in value of the tires. When moving the steering wheel while parked, a "squeaking" sound can be heard, and the steering wheel sticks. Applying lubricant to the components can resolve this issue. Steering wheel obstruction is the most common cause of steering wheel sticking, possibly due to improperly placed floor mats. Try adjusting the position of the floor mats.

I've been driving my Excelle for over a decade, and the steering stiffness issue is really annoying. Just helped a fellow car owner fix this problem recently - it's actually caused by lack of lubrication or rust in the steering column universal joint. You need to turn the wheels to full lock first, locate the steering column connection point under the chassis, then apply special grease to fill all the gaps. If the rust is severe, you'll need to replace it with new parts - the dealership now offers improved aluminum universal joints which are much more corrosion-resistant than the original iron ones. Worn steering rack bushings can also cause stiffness, which requires a lift to inspect the chassis. Remember to do a wheel alignment after repair, otherwise the pulling issue will be worse. Never ignore such mechanical problems - having the steering wheel suddenly lock up on the highway is no joke.

Last month I had this awful issue with sticky steering - it felt like the wheel was glued when driving on highways. Took it to my buddy's repair shop and after thorough checks, found error codes in the steering control module. Software conflicts can cause intermittent EPS failures. Flashing the latest ECU program made it much smoother. They also tested the torque sensor with a diagnostic tool - abnormal readings from this component can cause stickiness too. If the hardware fails, you'd need to replace the entire assembly, costing nearly 2k. Remember not to hold the steering at full lock for over 5 seconds when parking - it really strains the power steering pump. I recommend checking power steering fluid level during every service - replace immediately if it appears dark or cloudy.

Last time the stiffness in my Excelle's steering was due to a steering gear issue. The 4S shop detected excessive steering column backlash with diagnostic equipment, indicating internal gear wear. There's now a repair kit available to replace the improved bronze bushing, saving over 1,000 yuan compared to replacing the entire assembly. Another makeshift solution is to disassemble the steering wheel and apply high-temperature grease to the steering bearing for temporary relief. Remember to check the front suspension ball joints - their failure can also affect the steering gear. If you hear clunking noises when going over bumps, it's likely the steering tie rod is deformed. After these repairs, the electronic power steering system needs recalibration, otherwise the warning light won't reset.

I've handled several cases of stiff steering in the Buick Excelle, and found tire pressure has a significant impact. Especially in winter when temperatures drop, harder tires can exacerbate the heavy steering sensation. It's best to maintain the standard tire pressure of 2.5 for all four wheels - uneven pressure forces the steering gear to constantly make corrections. A faulty clock spring in the steering wheel can also cause stiffness; listen for rustling noises when turning to diagnose this. Those who've modified their steering wheels should note that overly thick heating pads can press against the clock spring. Replace torn steering column dust boots promptly, otherwise grit entering the steering knuckle will make turning feel like grinding sand.

I've found that steering stiffness is related to driving habits. Long-term one-handed steering can easily cause unilateral wear of the steering gears, resulting in uneven return force of the steering wheel. Now I always use both hands alternately when turning, and the stiffness issue has significantly reduced. During maintenance, I asked the mechanic to focus on checking the universal joint - lack of lubrication in this part can make it as stiff as a rusty door hinge. You can also open the hood yourself and spray some WD-40 lubricant on the steering column connection. If the stiffness is accompanied by a buzzing noise, it's definitely a problem with the power steering pump, which should be replaced as soon as possible to avoid breaking down halfway.
