on newer cars with fuel injection if fuel pump sterts getting weak it could cause that happened to me
that sounds like your transsion you should have it looked at although you can drive it with out reverse for quite a while
Sounds like a bad muffler bearing to me .......
Come to a full stop, put on the handbrake, change the gear to first (or drive) and begin driving forwards as normal. Do not try to put the car into a forward gear while you are still travelling backwards.
Shift to reverse
How would you get your car in and out of your driveway? How would you get out of a parking stall unless you pulled through and there was no curb or car blocking you? It is not uncommon to find yourself in a tight area where all you can do is reverse to get out while driving. I would say it is not safe.
Generally shifting from reverse to drive, while still rolling, is possible but not recommended. This places a lot of stress on the transmission and other components of the drive train.
It is a good idea to replace a carÕs suspension if it is rough to drive or ride in. Other reasons include uneven wear on tires and if the car drifts while driving.
You buckle up and you drive safe
A 350 engine will idle good but cut out and run rough while driving if there is a vacuum leak. This causes too much air to enter the engine under load.
I think texting while driving is a lot more dangerous than eating while driving, although I have not seen the relevant statistics.
have you tried to get your wheel realigned
If it is like mine--the squeaking will eventually occur all of the time while driving. I had to change the universal joints on the drive shaft at 70,000 miles. GM should be ashamed, with gas prices as high as they are, every mile on this truck has been driven gently.
