Hey guys, the dust boot on the control arm ball joint is torn. Is it necessary to replace it? Will it have a big impact if I don't?

Has anyone experienced a rattling noise from the front of an '08 Mazda 5 when driving on bumpy roads? I've just replaced the front shock absorber assembly, lower control arm, tie rod end, sway bar link, and stabilizer bar bushing, but the noise persists. Any ideas?

At the end of November, I replaced the control arm, steering rod, and axle assembly. Now the steering feels very light. When going over bumps, the steering wheel moves erratically. If I accelerate a bit aggressively, the steering veers off. Can someone help me out? [crying]

Guys, for the Middle East version of the '16, can this footboard be repaired? It's just the outer plastic that's slightly damaged. I don't want to replace the whole footboard.

I've replaced the control arm ball joints, steering rack, and shock absorbers, but the chassis still makes a thumping sound. What could be causing this?

My car was registered in 2018 and has just over 10,000 kilometers. It's been in the repair shop for half a month now. They said it's the electronic rocker arm that's broken. First, they tried replacing the spark plugs, but that didn't work. The ignition coil didn't work, and neither did the injectors. Then they said it's the electronic rocker arm. Wow, it costs 12,000. Sigh, they suggested I replace the engine, which is around 15,000. I don't even know what to do. This car isn't worth 50,000 now, and fixing it costs over 10,000.

There are knocking noises coming from the chassis, like "gudong gudong" and "gadeng gedeng". I replaced all 4 shock absorbers, but the noise persists. I checked the ball joints and the steering rack, but everything seems fine. Not sure where the noise is coming from in the Peugeot 301.

What should I do if the half shaft of my 2009 Jetta is worn out? The subframe and lower control arm were just replaced.

I have a 2017 Haima S5 manual 1.5T, and I'm facing some issues: the car door is rusted through, there's a noise from the chassis (note: I've replaced the lower control arm, ball joint, steering gear, and engine mount but still can't find the problem), and the USB port inside the car has poor connection. Is there anyone experiencing the same issues? Any solutions?

The repair shop suggested replacing the upper control arm bushing due to aging, but I found online that it might not be necessary. Any fellow car enthusiasts with experience who can help analyze this? The car has 84,000 kilometers on it currently.
