The rear end seems to be pretty tight. The only other noise that I get driving is climbing over small rocks and the curb in front of my house, I get a creaking from the front but the truck has over 250,000 on it now but the front is tight, no play in the steering wheel. I did notice that the stabilizer/sway bar whatever it's called seems to be loose, I can slide it side to side about 1/2" to 1" is this normal? the bushings dont have any cracks in them. Ive got stock tires on it, and the rims are fine. would the u-joints cause the front end to shimmy back and forth badly, with minimal vibration through the steering wheel?
