Re: Steering wheel vibration at speeds above 50mph
This could be a few things. if the odor was of rotton eggs...it's either a broken/loose motor mount that shakes the exhaust system causing the catalyitic converter to make that smell, or, in a worse case, its your transmission overheating and burning up ATF (automatic transmission fluid) and this is causing the torque converter plates to rotate out of harmony with each other causing the vibration. if the smell is more a burnt rubber, it's much more likely you have a timing issue or a worn main bearing on your crankshaft. this causes vibration and wear on the belts causing them to "burn" or emit that burnout smell. either way, take it to your mechanic right away because none of these problems will end well if left unattended. good luck!

If your tires are not balanced or you have a warped rim this will do this, especially at certain speeds you will notice it more, I would have your rims balanced first, and keep in mind if a rim is not able to be balanced it is warped.
From what you have described the disc rotors on the vehicle are distorted and could be fairly badly distorted if they have been subjected to excessive temperatures at any time.
This will translate into a pulsation in the brake pedal - especially noticeable when you brake at speeds above about 40mph. At 60 mph - as you found - you cannot miss it. At higher speeds you will also get some vibration through the steering wheel once you brake.
The disc rotors will need to be examined and removed from the car for machining or total replacement. They may be too worn or distorted for machining as the manufacturers specify a minimum safe disc rotor thickness. Disc rotors don't last the life of the car and replacing them is a fairly routine exercise and not usually expensive except on many European cars and on many prestige brands. The brake pads should also be replaced at the same time unless replaced recently and have minimal wear. The operation of the brake calipers should also be checked.
If you had a wheel balance problem on the car (rectified with a decent re-balance of both front wheels) you would find a constant vibration through the steering wheel at a given speed usually above about 45mph. What you have complained of is vibration only upon braking plus a pulsation through the brake pedal whilst braking. However if you are also noticing a constant vibration through the steering wheel at or above a given speed when cruising you need to have the front wheels re-balanced and the front suspension and steering checked for problems. If you have uneven tyre wear you will also need to have the front wheels re-aligned. If a front wheel alignment was not done on the car in the last 12000 miles it will need a wheel alignment in any event.
sound like the u-joints in the driveshaft. Lay under the truck and where the u-joints are try moving the driveshaft up and down. If it moves then the u-joints are bed. This will cause a tremendous vibration under a load and the faster it spins it will smooth out.
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
