Making Noise in reverse

[mattro]

I bought a silverado reg cab 4.3l v6 5sp 4x4 1999 new body style about 4 weeks ago and now

well when i put my truck in reverse today it made a screetching noise then i put it in 1st and nothing. I just bought it and off roaded it about three times once it got stuck front axle barried and rear close i wonder if that could cause it. I did my best to clean under the chassis with a hose and screwdriver cleaning out the dirt chunks. Oh yah its shaking anywere from 50mph and up and it may just be out of alingment. Well if you guys and girls could help me with those problems id be greatful.

 

Thanks

It also makes a slight noise in 1st....brought it to a mechanic today and he said its prolly the rear end or the driveshaft and it will be pricey. How much are those two? I sure hope its not too much but hey someone get back to me please...this forum hasnt been any help so far
