Front end vibration at 40 mph and rubbing sound

Hi, you could check your engine mounts.

There are many stages of vibration. The most common is in the steering and USUALLY a steering dampner will correct this. However, your description is not real defined and until the technician actually experiences it, it cannot be properly diagnosed

can you video it? could be many things could be a wheel bearing

steering idler sounds like its worn, on the steering you will see a link that goes from the steering arm just before the tracking, looks like a swing, it attaches to the body shell and has a bolt and rubber innards, this dampens down the vibration on the longest arm to the wheel so on right hand drive its on left wheel on left hand drives its on the right side, should not have a lot of play in it but should move left to right depending on steering position. cirb clipping wears them out quicker and so does pot holes in the road.

sounds like a bent wheel rim

car could need and alignment or you can have bad bushing or tie rod ends. need to get it looked at

Does the left front go click, click, click on tight slow turns.

front wheels need to be balanced, take it to a tyre shop and get it done.

sounds like you got the D.W (death wobble)
It is usually caused by either a bad tire,an off balanced, worn bushings, bad tracbar or loose steering components.

That sounds like a left front wheel bearing gone bad My friend.. turning right transfers weight to the left side and it probably has a roar similar to a turbo fan jet.. Try it and lemmie know.. thank you
