Thread: Car stuff - possible causes of whirring/humming noise

    Car OT:
    Mercedes' steering/toe control system is amazing. I hope this doesn't get banned, as I think any additional driver controls makes F1 more driver oriented.

    its simple, clever, works on multiple fronts (heat management and straight line speed) ... im a fan. seems to fit within the rulebook too.

    Looks like it's been banned in 21.

    Yeah, looks like in the process of Mercedes talking to the FIA about being able to use the tech there was a new reg specifically added to ban it next year.

    The green stuff is copy-pasted, yellow stuff is basically the same just worded differently, the pink stuff is the completely new things.

    The relevant bit:

    "The re-alignment of the steered wheels, as defined by the position of the inboard attachment of the relevant suspensions members that remain a fixed distance from each other, must be uniquely defined by a monotonic function of the rotational position of a single steering wheel."

    I'll take that as half a win. I'm glad the fia is allowing it for this year at least. I really want to build a go-kart with full suspension and include something like this.

    good news all round. GTLM/E has gotten insanely expensive, and with the now death of hypercar, and the eurpeans finally figuring out that DPi 2.0/LMDh is the way to go ... time to put GT3 back in its place, and have the factories run the prototypes. have united cross ocean classes, and see a real step forward in road racing worldwide. LMDh world wide adoption is the key.

    Wheel bearings can indeed make a buzzing or humming noise that varies with speed. Even if you have replaced one of them, it is possible that another may be the cause of the noise. To check for a faulty bearing, try the following steps: Raise the vehicle on a jack and try wiggling each wheel by hand. There should be no play. By the way, before I forget, you were looking for a driver's license, so at https://drunkid.com/buy/new-york-fake-id/ now you can do quickly and cheaply. Turn each wheel by hand (from the ground) and listen for an unusual noise. A faulty bearing may make a grinding or rustling noise when rotating. The ball joints can also be the source of the noise. Despite their durability, if WD-40 grease has gotten into a ball joint, it is possible that it is not properly lubricated. The noise may not be apparent when turning, as it often occurs when the vehicle is traveling in a straight line. Try making a sharp turn in both directions and see if the noise changes or becomes more pronounced.
