i had this old truck for a year now and never got any worse,after you drive it 10-20 miles and come to a stop it makes a grinding noise in the rear end like 2 gears slipping for a second then its fine till the next stop sign,doesn't make any noise other than that,let it sit a while and it wont do it if i have some one look at it,oil is full, don't seem to get hot,and on real cold days it wont do it and it sounds good down the road
