Popping noise when going over a bump in 2000 Bravada

[dmontgomery]

My latest problem with my 2000 Bravada seems to be with the axles.

1) I hear popping noises and sometimes a grind from the front end when turning sharply at a low speed. Such as when pulling into a parking spot.

2) I hear the same popping noise from the rear right axle when hitting a large bump I hear the noise when the vehicle comes down not when going up.

I get the oil changed and the vehicle lubed every 3,000 miles. The dealership doing the warranty work is claiming that all it needed was greased and that whomever is lubing did it wrong. I don't agree. The noises have went away for right now but I have a feeling they will be back soon. Does anyone have any suggestions as to what to look into?

Worn out shock bushings or broken exhaust hanger?
